Westpac Banking Corporation - New Zealand Banking Group9

Note 1 Financial statements preparation
The Overseas Bank is registered as a public company limited by shares under the Australian Corporations Act 2001 and is entered on the register

maintained under the BPS Act. The Overseas Bank provides a broad range of banking and financial services, including consumer, business and

institutional banking and wealth management services.

The NZ Branch’s head office is situated at Westpac on Takutai Square, 16 Takutai Square, Auckland 1010, New Zealand and the address for service

of process on the NZ Branch is General Counsel, Legal, Westpac on Takutai Square, 53 Galway Street, Auckland 1010, New Zealand.

The financial statements are for the NZ Banking Group.

These financial statements were authorised for issue by the Overseas Bank’s Board of Directors on 11 November 2025. The Board has the power to

amend and reissue the financial statements.

The material accounting policies are set out below and in the relevant notes to the financial statements. These policies have been consistently

applied to all the years presented, unless otherwise stated.

a. Basis of preparation

(i) Basis of accounting

These financial statements are general purpose financial statements prepared in accordance with:

●the requirements of the Financial Markets Conduct Act 2013; and

●the requirements of the Order.

These financial statements comply with New Zealand Generally Accepted Accounting Practice, applicable NZ IFRS and other authoritative

pronouncements of the XRB, as appropriate for for-profit entities. These financial statements also comply with International Financial Reporting

Standards Accounting Standards, as issued by the International Accounting Standards Board.

All amounts in these financial statements have been rounded to the nearest million dollars unless otherwise stated.

(ii) Historical cost convention

These financial statements have been prepared under the historical cost convention, as modified by applying fair value accounting to financial

assets and financial liabilities (including derivative instruments) measured at FVIS or FVOCI.

(iii) Comparative revisions

Comparative information has been revised where appropriate to conform to changes in presentation in the current year and to enhance

comparability. Where there has been a material restatement of comparative information the nature of, and the reason for, the restatement is

disclosed in the relevant section.

(iv) Standards adopted during the year ended 30 September 2025

No new accounting standards have been adopted by the NZ Banking Group for the year ended 30 September 2025. There have been no

amendments to existing accounting standards that have had a material impact to the NZ Banking Group.

(v) Business combinations

Business combinations are accounted for using the acquisition method of accounting. Acquisition cost is measured as the aggregate of the fair

value at the date of acquisition of the assets given, equity instruments issued or liabilities incurred or assumed. Acquisition-related costs are

expensed as incurred (except for those costs arising on the issue of equity instruments which are recognised directly in equity).

Identifiable assets acquired and liabilities and contingent liabilities assumed in a business combination are measured at fair value on the

acquisition date. Goodwill is measured as the excess of the acquisition cost, the amount of any non-controlling interest and the fair value of any

previous NZ Banking Group’s equity interest in the acquiree, over the fair value of the identifiable net assets acquired.

(vi) Foreign currency translation

Functional and presentation currency

The financial statements are presented in New Zealand dollars which is the NZ Banking Group’s functional and presentation currency.

Transactions and balances

Foreign currency transactions are translated into the functional currency using the exchange rates prevailing at the dates of the transactions. FX

gains and losses resulting from the settlement of such transactions and from the translation at year end exchange rates of monetary assets and

liabilities denominated in foreign currencies are recognised in the income statement, except when deferred in OCI for qualifying cash flow hedges.

Notes to the financial statements

10Westpac Banking Corporation - New Zealand Banking Group

Note 1 Financial statements preparation (continued)
b. Basis of aggregation

The NZ Banking Group as at 30 September 2025 has been aggregated by combining the sum of the capital and reserves of the NZ Branch, and the

consolidated capital and reserves of Westpac New Zealand Group Limited, BT Financial Group (NZ) Limited, Westpac Financial Services Group-

NZ-Limited, Westpac Group Investment-NZ-Limited, and their subsidiaries (including structured entities). For New Zealand entities acquired by

the Overseas Banking Group, capital and reserves at acquisition are netted and recognised as capital contributed to the NZ Banking Group.

Subsidiaries are entities over which the members of the NZ Banking Group have control as they are exposed to, or have rights to, variable returns

from their involvement with the entities, and can affect those returns through their power over the entities. All transactions between entities within

the NZ Banking Group are eliminated. Subsidiaries are fully consolidated from the date on which control commences and are de-consolidated

from the date that control ceases.

c. Financial assets and financial liabilities

(i) Recognition

Financial assets and financial liabilities, other than regular way transactions, are recognised when the NZ Banking Group becomes a party to the

terms of the contract, which is generally on the settlement date (the date payment is made or cash advanced). Purchases and sales of financial

assets in regular way transactions are recognised on the trade date (the date on which the NZ Banking Group commits to purchase or sell an

asset).

(ii) Derecognition

Financial assets are derecognised when the rights to receive cash flows from the asset have expired, or when the NZ Banking Group has either

transferred its rights to receive cash flows from the asset or has assumed an obligation to pay the received cash flows in full under a ‘pass through’

arrangement and transferred substantially all the risks and rewards of ownership.

There may be situations where the NZ Banking Group has partially transferred the risks and rewards of ownership but has neither transferred nor

retained substantially all the risks and rewards of ownership. In such situations, the asset continues to be recognised on the balance sheet to the

extent of the NZ Banking Group’s continuing involvement in the asset.

Financial liabilities are derecognised when the obligation is discharged, cancelled or expires. Where an existing financial liability is replaced by

another from the same lender on substantially different terms, or the terms of an existing liability are substantially modified, the exchange or

modification is treated as a derecognition of the original liability and the recognition of a new liability, with the difference in the respective carrying

amounts recognised in the income statement.

The terms are deemed to be substantially different if the discounted present value of the cash flows under the new terms (discounted using the

original effective interest rate) is at least 10% different from the discounted present value of the remaining cash flows of the original financial

liability. Qualitative factors such as a change in the currency the instrument is denominated in, a change in the interest rate from fixed to floating

and conversion features are also considered.

(iii) Classification and measurement basis

Financial assets

Financial assets are grouped into the following classes: cash and balances with central banks, collateral paid, trading securities and financial

assets measured at FVIS, derivative financial instruments, investment securities, loans, other financial assets and due from related entities.

Financial assets are classified based on a) the business model within which the assets are managed, and b) whether the contractual cash flows of

the instrument represent SPPI.

The NZ Banking Group determines the business model at the level that reflects how groups of financial assets are managed. When assessing the

business model the NZ Banking Group considers factors including how performance and risks are managed, evaluated and reported and the

frequency and volume of, and reason for, sales in previous periods and expectations of sales in future periods.

When assessing whether contractual cash flows are SPPI, interest is defined as consideration primarily for the time value of money and the credit

risk of the principal outstanding. The time value of money is defined as the element of interest that provides consideration only for the passage of

time and not consideration for other risks or costs associated with holding the financial asset. Terms that could change the contractual cash flows

so that they may not meet the SPPI criteria include contingent and leverage features, non-recourse arrangements, and features that could modify

the time value of money.

Debt instruments

If the debt instruments have contractual cash flows which represent SPPI on the principal balance outstanding they are classified at:

●amortised cost if they are held within a business model whose objective is achieved through holding the financial asset to collect these cash

flows; or

●FVOCI if they are held within a business model whose objective is achieved both through collecting these cash flows and selling the financial

asset; or

●FVIS if they are held within a business model whose objective is achieved through selling the financial asset.

Notes to the financial statements

Westpac Banking Corporation - New Zealand Banking Group11

Note 1 Financial statements preparation (continued)
Debt instruments are classified and measured at FVIS where the contractual cash flows do not represent SPPI on the principal balance outstanding

or where it is designated at FVIS to eliminate or reduce an accounting mismatch.

Debt instruments at amortised cost are initially recognised at fair value and subsequently measured at amortised cost using the effective interest

method. They are presented net of any provision for ECL determined using the ECL model. Refer to Notes 6 and 12 for further details.

Debt instruments at FVOCI are measured at fair value with unrealised gains and losses recognised in OCI except for interest income, impairment

charges and FX gains and losses, which are recognised in the income statement. Impairment on debt instruments at FVOCI is determined using

the ECL model and is recognised in the income statement with a corresponding amount in OCI. There is no reduction of the carrying value of the

debt security which remains at fair value.

The cumulative gain or loss recognised in OCI is subsequently recognised in the income statement when the instrument is derecognised.

Debt instruments at FVIS are measured at fair value with subsequent changes in fair value recognised in the income statement.

Financial liabilities

Financial liabilities are grouped into the following classes: collateral received, deposits and other borrowings, other financial liabilities, derivative

financial instruments, due to related entities, debt issues and loan capital.

Financial liabilities are measured at amortised cost if they are not held for trading or designated at FVIS, otherwise they are measured at FVIS.

Financial assets and financial liabilities measured at FVIS are recognised initially at fair value. All other financial assets and financial liabilities are

recognised initially at fair value plus or minus directly attributable transaction costs respectively.

Further details of the accounting policy for each category of financial asset or financial liability mentioned above are set out in the note for the

relevant item.

The NZ Banking Group’s policies for determining the fair value of financial assets and financial liabilities are set out in Note 24.

d. Critical accounting assumptions and estimates

Applying the NZ Banking Group’s accounting policies requires the use of judgement, assumptions and estimates which impact the financial

information. The significant assumptions and estimates used are discussed in the relevant notes below.

●Note 12Provision for expected credit losses

●Note 24Fair values of financial assets and financial liabilities

During the six months ended 31 March 2025, geopolitical developments, including in relation to international trade and tariff policies, global

tensions and continuing global military conflict, led to heightened uncertainty as to future economic forecasts and potential impact on the NZ

Banking Group and its customers. Responding to this heightened uncertainty, the NZ Banking Group increased the weighting of the downside

scenario used in the estimate of ECL from 42.5% to 45% in March 2025 (refer to Note 12 for further details). As at 30 September 2025, estimates of

ECL remain subject to this higher than usual level of uncertainty.

Impact of climate-related risks

The NZ Banking Group has considered the potential risk of climate change on its financial statements. Refer to Note 31 for further details.

e. Future developments in accounting standards

NZ IFRS 9 Financial Instruments (NZ IFRS 9) became effective for the NZ Banking Group for the financial year ended 30 September 2019. When

adopted, as permitted by the standard, the NZ Banking Group elected to continue to comply with the hedge accounting requirements under NZ

IAS 39 Financial Instruments: Recognition and Measurement (NZ IAS 39). The NZ Banking Group intends to adopt the hedge accounting

requirements of NZ IFRS 9 prospectively for the financial year beginning 1 October 2025, for designated hedge relationships other than fair value

hedges of the interest rate exposure of a portfolio of financial assets or financial liabilities (fair value macro hedges) which will continue to be

accounted for under NZ IAS 39, as dynamic portfolio risk management is out of scope of NZ IFRS 9. All the NZ Banking Group's existing hedge

accounting relationships will continue to qualify for hedge accounting. Under NZ IFRS 9, costs of hedging associated with cross currency basis risk

will be reflected in a new cost of hedging reserve (COHR). The quantum of this impact will be based on the valuation of derivatives at the time.

NZ IFRS 18 Presentation and Disclosure in Financial Statements (NZ IFRS 18) was issued in May 2024 and will be effective for the 30 September

2028 year end unless early adopted. NZ IFRS 18 will replace NZ IAS 1 Presentation of Financial Statements. This standard will not change the

recognition and measurement of items in the financial statements, but will impact the presentation and disclosure in the financial statements,

including:

●New categories and subtotals in the income statement to enhance comparability;

●Enhancing the disclosure of management defined performance measures; and

●Changes to the grouping of information in the financial statements to provide more useful information.

The NZ Banking Group is continuing to assess the impact of adopting NZ IFRS 18.

Notes to the financial statements

12Westpac Banking Corporation - New Zealand Banking Group

Note 1 Financial statements preparation (continued)
Amendments to the Classification and Measurement of Financial Instruments was issued in June 2024 and amends NZ IFRS 7 Financial

Instruments: Disclosures and NZ IFRS 9 Financial Instruments. It is effective for the 30 September 2027 year end unless early adopted.

The amendments include:

●Changes to disclosures for investments in equity instruments designated at FVOCI and additional disclosures for financial instruments with

contingent features that do not relate directly to basic lending risks and costs;

●Guidance on derecognition of financial liabilities criteria when using an electronic payments system; and

●Guidance on assessing contractual cash flow characteristics of financial assets with ESG and similar features.

The NZ Banking Group is continuing to assess the impact of adopting the amendments.

Other new standards and amendments to existing standards that are not yet effective are not expected to have a material impact on the NZ

Banking Group.

Note 2 Net interest income
Accounting policy

Interest income and interest expense for all interest earning financial assets and interest bearing financial liabilities at amortised cost or FVOCI,

detailed within the table below, are recognised using the effective interest method. Net income from Treasury’s interest rate and liquidity

management activities and the cost of the Depositor Compensation Scheme levy are included in net interest income.

The effective interest method calculates the amortised cost of a financial instrument by discounting the financial instrument’s estimated future

cash receipts or payments to their present value and allocates the interest income or interest expense, including any fees, costs, premiums or

discounts integral to the instrument, over its expected life.

Interest income is calculated based on the gross carrying amount of financial assets in stages 1 and 2 of the NZ Banking Group's ECL model and

on the carrying amount net of the provision for ECL for financial assets in stage 3.

Note 3 Non-interest income
Accounting policy

Non-interest income includes net fees and commissions income, net wealth management income, trading income and other income.

Net fees and commissions income

When another party is involved in providing goods or services to a NZ Banking Group customer, the NZ Banking Group assesses whether the

nature of the arrangement with its customer is as a principal provider or an agent of another party. Where the NZ Banking Group is acting as an

agent for another party, the income earned by the NZ Banking Group is the net consideration received (i.e. the gross amount received from the

customer less amounts paid to a third party provider). As an agent, the net consideration represents fees and commissions income for

facilitating the transaction between the customer and the third party provider with primary responsibility for fulfilling the contract.

Fees and commissions income

Fees and commissions income is recognised when the performance obligation is satisfied by transferring the promised good or service to the

customer. Fees and commissions income includes facility fees, transaction fees and commissions and other non-risk fee income. Commissions

income includes commissions received for the distribution of general and life insurance products.

Facility fees include certain line fees, annual credit card fees and fees for providing customer bank accounts. They are recognised over the term

of the facility/period of service on a straight line basis.

Transaction fees and commissions are earned for facilitating banking transactions such as FX and telegraphic transfers. Fees and commissions

for these one-off transactions are recognised once the transaction has been completed. Transaction fees and commissions are also recognised

for credit card transactions including interchange fees net of scheme charges. These are recognised once the transaction has been completed,

however, a component of interchange fees received is deferred as unearned income as the NZ Banking Group has a future service obligation to

customers under the NZ Banking Group’s credit card reward programmes.

Other non-risk fee income includes advisory and underwriting fees which are recognised when the related service is completed.

Income which forms an integral part of the effective interest rate of a financial instrument is recognised using the effective interest method and

recorded in interest income (for example, loan origination fees).

Fees and commissions expenses

Fees and commissions expenses include incremental external costs that vary directly with the provision of goods or services to customers. An

incremental cost is one that would not have been incurred if a specific good or service had not been provided to a specific customer. Fees and

commissions expenses which form an integral part of the effective interest rate of a financial instrument are recognised using the effective

interest method and recorded in net interest income. Fees and commissions expenses include the costs associated with credit card loyalty

programmes which are recognised as an expense when the services are provided on the redemption of points.

Net wealth management income

Wealth management fees earned for the ongoing management of customer funds and investments are recognised when the performance

obligation is satisfied which is over the period of management.

Trading income

●Realised and unrealised gains or losses from changes in the fair value of trading assets, liabilities and derivatives are recognised in the

period in which they arise (except day one profits or losses which are deferred, refer to Note 24); and

●Net income related to Treasury’s interest rate and liquidity management activities is included in net interest income.

disclosures paid to PwC.

It is the NZ Banking Group’s policy to engage the external auditor on assignments additional to their statutory audit duties only if their

independence is not impaired or seen to be impaired, and where their expertise and experience with the NZ Banking Group is important.

Fees for the audit of the PIE Funds' (as defined in Note 22) financial statements for the year ended 30 September 2025 of $55,000 (30 September

2024: $36,383) were paid to PwC due to the timing of the external auditor transition, as the PIE Funds' balance date is 31 March. As PwC are not the

NZ Banking Group's external auditor for the year ended 30 September 2025, this is not included in the table above.

Audit and non-audit assurance services are provided to non-consolidated entities, including non-consolidated trusts and non-consolidated

superannuation funds or pension funds of which a member of the NZ Banking Group is manager or responsible entity. During the year ended 30

September 2025, the fees in respect of these services were nil paid to KPMG and $512,970 paid to PwC, due to the timing of the external auditor

transition as the balance date of the non-consolidated trusts and non-consolidated superannuation funds or pension funds is 31 March (30

September 2024: $490,392 paid to PwC). This amount is not included in the table above.

Note 6 Impairment charges/(benefits)
Accounting policy

Impairment charges are based on an expected loss model which measures the difference between the current carrying amount and the present

value of expected future cash flows taking into account past experience, current conditions and multiple probability-weighted macroeconomic

scenarios for reasonably supportable future economic conditions. Further details of the calculation of ECL and the critical accounting

assumptions and estimates relating to impairment charges are included in Note 12.

Impairment charges are recognised in the income statement, with a corresponding amount recognised as follows:

●Loans at amortised cost: as a reduction of the carrying value of the financial asset through an offsetting provision account (refer to Note

12);

●Investment securities: in reserves in OCI with no reduction of the carrying value of the debt security (refer to the statement of changes in

equity); and

●Credit commitments: as a provision (refer to Note 19).

Uncollectable loans

A loan may become uncollectable in full or part if, after following the NZ Banking Group’s loan recovery procedures, the NZ Banking Group

remains unable to collect that loan’s contractual repayments. Uncollectable amounts are written off against their related provision for ECL, after

all possible repayments have been received.

Where loans are secured, amounts are generally written off after receiving the proceeds from the security, or in certain circumstances, where

the net realisable value of the security has been determined and this indicates that there is no reasonable expectation of full recovery, write-off

may be earlier. Unsecured consumer loans are generally written off after 180 days past due.

The NZ Banking Group may subsequently be able to recover cash flows from loans written off. In the period which these recoveries are made,

they are recognised in the income statement.

Note 7 Income tax expense
Accounting policy

The income tax expense for the year comprises current and deferred tax. Tax is recognised in the income statement, except to the extent that it

relates to items recognised directly in OCI, in which case it is recognised in the statement of comprehensive income.

Current tax is the tax payable for the year using enacted or substantively enacted tax rates and laws. Current tax also includes adjustments to

tax payable for previous years.

Judgement is required in determining the current tax liability. There may be transactions with uncertain tax outcomes and provisions are

determined based on the expected outcomes.

Goods and services tax

Revenue, expenses and assets are recognised net of GST except to the extent that GST is not recoverable from the New Zealand Inland Revenue.

In these circumstances, GST is recognised as part of the expense or the cost of the asset.

Pillar Two introduces new 'top-up' taxes for multinational enterprises ('MNEs') within the scope of the rules to ensure that these MNEs pay a

minimum effective tax rate of 15% on profits in all jurisdictions.

The NZ Banking Group is part of an MNE group under the Overseas Bank that falls within the Organisation for Economic Co-operation and

Development Pillar Two Model Rules. Pillar Two legislation has been enacted in New Zealand and will take effect from the NZ Banking Group's

financial year beginning 1 October 2025. Based on an assessment of the most recent tax filings and financial statements for its constituent entities,

the NZ Banking Group does not expect a material exposure, if any, to Pillar Two income taxes.

Debt securities measured at FVOCI

Includes debt instruments that have contractual cash flows which represent SPPI on the principal balance outstanding and they are held within a

business model whose objective is achieved both through collecting these cash flows or selling the financial asset.

These securities are measured at fair value with unrealised gains and losses recognised in OCI except for interest income, impairment charges

and FX gains and losses and fair value hedge adjustments which are recognised in the income statement.

Impairment is measured using the same ECL model applied to financial assets measured at amortised cost. Impairment is recognised in the

income statement with a corresponding amount in OCI with no reduction of the carrying value of the debt security which remains at fair value.

Refer to Note 12 for further details.

The cumulative gain or loss recognised in OCI is subsequently recognised in the income statement when the instrument is disposed.

Note 11 Loans
Accounting policy


Loans are financial assets initially recognised at fair value plus directly attributable transaction costs and fees.

Loans are subsequently measured at amortised cost using the effective interest method where they have contractual cash flows which represent

SPPI on the principal balance outstanding and they are held within a business model whose objective is achieved through holding the loans to

collect these cash flows. They are presented net of any provision for ECL.

Loan products that have both mortgage and deposit facilities are presented gross on the balance sheet, segregating the asset and liability

component, because they do not meet the criteria to be offset. Interest earned on these products is presented on a net basis in the income

statement as this reflects how the customer is charged.

Note 12 Provision for expected credit losses
Accounting policy

Note 6 provides details of impairment charges/(benefits).

Impairment applies to all financial assets at amortised cost, debt securities measured at FVOCI and credit commitments.

The ECL is recognised as follows:

●Loans: as a reduction of the carrying value of the financial asset through an offsetting provision account (refer to Note 11);

●Investment securities: in reserves in OCI with no reduction of the carrying value of the debt security itself (refer to the statement of

changes in equity); and

●Credit commitments: as a provision (refer to Note 19).

Measurement

The NZ Banking Group calculates the provision for ECL based on a three stage approach. The provision for ECL is a probability-weighted

estimate of the cash shortfalls expected to result from defaults over the relevant timeframe. They are determined by evaluating a range of

possible outcomes and taking into account the time value of money, past events, current conditions and forecasts of future economic

conditions.

The models use three main components to determine the ECL (as well as the time value of money) including:

●PD: the probability that a counterparty will default;

●LGD: the loss that is expected to arise in the event of a default; and

●EAD: the estimated outstanding amount of credit exposure at the time of the default.

Model stages

The three stages are as follows:

Stage 1: 12 months ECL - performing

For financial assets where there has been no significant increase in credit risk since origination a provision for 12 months ECL is recognised.

Stage 2: Lifetime ECL – performing

For financial assets where there has been a significant increase in credit risk since origination but where the asset is still performing a provision

for lifetime ECL is recognised. The indicators of a significant increase in credit risk are described on the following page.

Stage 3: Lifetime ECL – non-performing

Financial assets in Stage 3 are those that are in default. A default occurs when:

●The NZ Banking Group considers that the customer is unable to repay its credit obligations in full, irrespective of recourse by the NZ

Banking Group to action such as realising security. Indicators include a breach of contract with the NZ Banking Group such as a default on

interest or principal payments, a borrower experiencing significant financial difficulties or observable economic conditions that correlate

to defaults on an individual basis; or

●The customer is more than 90 days past due on any material credit obligation.

A provision for lifetime ECL is recognised on these financial assets.

Collective and individual assessment

Financial assets that are in Stages 1 and 2 are assessed on a collective basis. This means that they are grouped in pools of similar assets with

similar credit risk characteristics including the type of product and CRG. Financial assets in Stage 3 are assessed on an individual basis and

calculated collectively for those below a specified threshold.

Expected life

In considering the lifetime timeframe for ECL in Stages 2 and 3, the standard generally requires use of the remaining contractual life adjusted,

where appropriate, for prepayments, extension and other options. For certain revolving credit facilities which include both a drawn and undrawn

component (e.g. credit cards and revolving lines of credit), the NZ Banking Group’s contractual ability to demand repayment and cancel the

undrawn commitment does not limit the exposure to credit losses to the contractual notice period. For these facilities, lifetime is based on

historical behaviour.

Movement between stages

Financial assets may move in both directions through the stages of the impairment model. Financial assets previously in Stage 2 may move back

to Stage 1 if it is no longer considered that there has been a significant increase in credit risk. Similarly, financial assets in Stage 3 may move back

to Stage 1 or Stage 2 if they are no longer assessed to be non-performing.

Notes to the financial statements

22Westpac Banking Corporation - New Zealand Banking Group

Note 12 Provision for expected credit losses (continued)
Accounting policy (continued)

Critical accounting assumptions and estimates

Key judgements include when a significant increase in credit risk has occurred, the estimation of forward-looking macroeconomic information

and overlays. Other factors which can impact the provision include the borrower’s financial situation, the realisable value of collateral, the NZ

Banking Group’s position relative to other claimants, the reliability of customer information and the likely cost and duration of recovering the

loan.

Significant increase in credit risk

Determining when a financial asset has experienced a significant increase in credit risk since origination is a critical accounting judgement which

is based on the change in the PD since origination. In determining whether a change in PD represents a significant increase in risk, relative

changes in PD and absolute PD thresholds are both considered based on the portfolio of the exposure.

The NZ Banking Group does not rebut the presumption that instruments that are 30 days past due have experienced a significant increase in

credit risk, but this is used as a backstop rather than the primary indicator.

Forward-looking macroeconomic information

The measurement of ECL for each stage and the assessment of significant increase in credit risk consider information about past events and

current conditions as well as reasonable and supportable projections of future events and economic conditions. The estimation of forward-

looking information is a critical accounting judgement. The NZ Banking Group considers three future macroeconomic scenarios including a base

case scenario along with upside and downside scenarios.

The macroeconomic variables used in these scenarios, based on current economic forecasts, include (but are not limited to) unemployment

rates, real GDP growth rates, base interest rates and residential property price indices.

●Base case scenario

This scenario utilises the internal Westpac Economic forecasts used for strategic decision making and forecasting.

●Upside scenario

This scenario represents a modest improvement on the base case scenario.

●Downside scenario

The downside scenario is a more severe scenario with ECL higher than those under the base case scenario. This scenario assumes a

recession with a combination of negative GDP growth, declines in residential property prices and an increase in the unemployment rate,

which simultaneously impact ECL across all portfolios from the reporting date.

The three macroeconomic scenarios are probability weighted and together represent the NZ Banking Group’s view of the forward-looking

distribution of potential loss outcomes. The weighting applied to each of the three macroeconomic scenarios takes into account historical

frequency, current trends, and forward-looking conditions.

The macroeconomic variables and probability weightings of the three macroeconomic scenarios are subject to the approval of the NZ Banking

Group’s Chief Financial Officer and Chief Risk Officer with oversight from the Board of Directors (and its Committees).

Portfolio overlays

Where appropriate, adjustments will be made to modelled outcomes to reflect reasonable and supportable information not already

incorporated in the models. These adjustments (overlays) may be an increase or decrease in the provision for ECL.

Judgements can change with time as new information becomes available which could result in changes to the provision for ECL.

Comparatives have been revised to remove credit exposures offered and accepted but still revocable.

Movements in components of loss allowance

The reconciliation of the provision for ECL for loans and credit commitments has been determined by an aggregation of monthly movements over

the year. The key line items in the reconciliation represent the following:

●“Transfers between stages” represents transfers between Stage 1, Stage 2 and Stage 3 prior to remeasurement of the provision for ECL.

●“New facilities originated” represents new accounts originated during the year.

●“Facilities derecognised” represents loans derecognised due to final repayments during the year.

●“Other charges/(credits) to the income statement” represents the impact on the provision for ECL due to changes in credit quality during

the year (including transfers between stages), changes in portfolio overlays, changes in key economic assumptions and partial repayments

and additional drawdowns on existing facilities over the year.

●"Amounts written off" represents a reduction in the provision for ECL as a result of derecognition of exposures where there is no reasonable

expectation of full recovery.

Impact of overlays on the provision for ECL on loans and credit commitments

The following table attributes the provision for ECL on loans and credit commitments between individually assessed and collectively assessed

provisions. Collectively assessed provisions are disaggregated into the modelled ECL provision and portfolio overlays.

Portfolio overlays are used to capture areas of potential risks and uncertainties that are not captured in the underlying modelled ECL.

Details of changes related to forward-looking economic inputs and portfolio overlays, based on reasonable and supportable information up to the

date of this disclosure statement, are provided below.

(a) Modelled provision for ECL on loans and credit commitments

The modelled provision for ECL on loans and credit commitments is a probability weighted estimate based on three scenarios which together

represent the NZ Banking Group’s view of the forward-looking distribution of potential loss outcomes. The changes in provisions as a result of

changes in modelled ECL are reflected through the “Other charges/(credits) to the income statement” line in the “Movements in components of

loss allowance” table. Overlays are used to capture potential risks and uncertainties that are not captured in the underlying modelled ECL.

The base case scenario uses the latest Westpac Economics forecast. Certain data points from this forecast are shown below:

The downside scenario is an economic downturn scenario with ECL higher than the base case. This scenario assumes a recession with a

combination of negative GDP growth, declines in residential property prices and an increase in the unemployment rate, which simultaneously

impact ECL across all portfolios from the reporting date. The assumptions used in this scenario and relativities to the base case will be monitored

having regard to the emerging economic conditions and updated where necessary. The upside scenario represents a modest economic

improvement to the base case.

The following sensitivity table shows the reported provision for ECL on loans and credit commitments based on the probability weighted scenarios

and what the provision for ECL on loans and credit commitments would be assuming a 100% weighting is applied to the base case scenario and to

the downside scenario (with all other assumptions held constant).

If 1% of the Stage 1 gross exposure from loans and credit commitments (calculated on a 12 month ECL were transferred to Stage 2 (calculated on a

lifetimeECL) the provision for ECL on loans and credit commitments would increase by $17 million (30 September 2024: $14 million). If 1% of Stage

2 loans and credit commitments (calculated on a lifetime ECL) were transferred to Stage 1 (calculated on a 12 month ECL), the provision for ECL on

loans and credit commitments would decrease by $(2) million (30 September 2024: $(3) million) for the NZ Banking Group. These estimates apply

the average modelled provision coverage ratio by stage to the transfer of loans and credit commitments.

same value, reflecting greater uncertainty in international trading relations and geopolitical instability.

(b) Portfolio overlays

Portfolio overlays are used to address areas of risk, including significant uncertainties that are not captured in the underlying modelled ECL. These

risks may result in under or overestimation of the modelled provision for ECL. Determination of portfolio overlays requires expert judgement and is

thoroughly documented and subject to comprehensive internal governance and oversight. Portfolio overlays are continually reassessed and if the

risk is judged to have changed (increased or decreased), or is subsequently captured in the modelled ECL, the portfolio overlays will be released

or remeasured.

The NZ Banking Group’s total portfolio overlays as at 30 September 2025 were $(27) million (30 September 2024: $(33) million), held on the

provision for ECL for residential mortgages to adjust for observed conservatism in the modelled outcome identified through model monitoring.

Impact of changes in gross carrying amount on the provision for ECL

●Stage 1 gross carrying amount had a net increase of $12.4 billion (30 September 2024: increased by $3.5 billion), primarily driven by new

lending and underlying portfolio movement from residential mortgages and corporate lending, partially offset by repayments. The Stage 1

ECL increase is in line with Stage 2 exposures movement to Stage 1, primarily driven by underlying portfolio movements and a more positive

economic outlook, partially offset by higher downside scenario weightings.

●Stage 2 gross carrying amount decreased by $8.2 billion (30 September 2024: decreased by $0.9 billion), primarily driven by the movement

of exposures to Stage 1, repayments and underlying portfolio movement from residential mortgages and corporate lending. The Stage 2 ECL

decrease is mainly as a result of the movement of exposures to Stage 1, primarily driven by underlying portfolio movements and an

improved economic outlook, partially offset by the increase in downside scenario weightings from residential mortgages and corporate

lending.

●Stage 3 gross carrying amount increased by $0.1 billion (30 September 2024: increased by $0.2 billion), driven by increases in 90 days past

due exposures from the residential mortgages lending, partially offset by repayments and releases due to write-offs from other retail

lending. The Stage 3 ECL increase is in line with the increase in Stage 3 exposures.

Refer to Note iii. Asset quality of the Registered bank disclosures for further details.

Write-offs still under enforcement activity

The amount of current year write-offs which remain subject to enforcement activity was $25 million (30 September 2024: $30 million).

Please refer to Note 31.1 for details of the NZ Banking Group’s overall Risk Management Framework.

●The Overseas Banking Group maintains a Credit Risk Management Framework, a Credit Risk Management Strategy, and a Credit Risk

Appetite Statement, and a number of supporting policies that define roles and responsibilities, acceptable practices, limits and key

controls.

●The Overseas Bank’s Credit Risk Management Framework describes the principles, methodologies, systems, roles and responsibilities,

reports and key controls for managing credit risk. Within the Credit Risk Management Framework, the NZ Banking Group has its own credit

approval limits approved by Westpac New Zealand’s Board and the Overseas Banking Group’s Chief Risk Officer.

●Westpac New Zealand's BRCC, Westpac New Zealand’s RISKCO and Westpac New Zealand’s CREDCO monitor the risk profile, performance

and management of the NZ Banking Group’s credit portfolio on at least a quarterly basis, and the development and review of key credit risk

policies are performed on at least an annual basis; other management reviews occur monthly or more frequently.

●Additionally, the NZ Branch Risk Committee monitors the risk profile, performance and management of the NZ Branch credit portfolio on a

quarterly basis. Other management reviews occur monthly or more frequently. Group BRiskC oversees the development and review of key

credit risk policies.

●The NZ Banking Group’s Credit Risk Rating System Policy describes the credit risk rating system philosophy, design, key features and uses of

rating outcomes.

●All models materially impacting the risk rating process are periodically reviewed in accordance with the NZ Banking Group’s model risk

policies.

●An annual review is performed of the Credit Risk Rating System for approval by the Overseas Banking Group’s Group Chief Credit Officer and

noting by Group BRiskC and Overseas Banking Group CREDCO.

●Specific credit risk estimates (including PD, LGD and EAD) are overseen and reviewed annually in line with the Overseas Banking Group’s

Model Risk Policy. Models are approved under delegated authority from the Overseas Banking Group’s Chief Risk Officer. Model Risk is

overseen by the Overseas Banking Group’s Model Risk Committee (a subcommittee of the Group BRiskC).

●In determining the provision for ECL, the forward-looking economic inputs and the probability weightings of the forward-looking scenarios

as well as any adjustments made to the modelled outcomes are subject to the approval of the NZ Banking Group’s Chief Financial Officer

and Chief Risk Officer with oversight from the Westpac New Zealand Board (and its Committees).

●Policies for delegating credit approval authorities and formal limits for the extension of credit are established throughout the NZ Banking

Group.

●Credit policies are established and maintained throughout the NZ Banking Group. They include policies governing the origination,

evaluation, approval, documentation, settlement and ongoing management of credit risks.

●Sector policies guide credit extension where industry-specific guidelines are considered necessary (e.g. acceptable financial ratios o r

permitted collateral).

●The Overseas Banking Group’s Related Entity Risk Management Policy and supporting policies govern credit exposures to related entities to

minimise the spread of credit risk between Overseas Banking Group entities and to comply with the prudential requirements prescribed by

APRA.

●Climate change-related credit risks are considered in line with the Overseas Banking Group’s Climate Change Position Statement and Action

Plan. Climate change risks are managed in line with the NZ Banking Group’s Risk Management Framework which is supported by the

Overseas Banking Group’s Sustainability Risk Management Framework, Westpac New Zealand's Climate Risk Policy, Westpac New

Zealand’s ESG Credit Risk Policy and Westpac New Zealand's and the Overseas Banking Group’s Board Risk Appetite Statements. Where

appropriate, these are applied at the portfolio, customer, and transaction level.

●Westpac New Zealand's CREDCO oversees work to identify and manage the potential impact on credit exposures from climate change-

related transition and physical risks across the NZ Banking Group.

●Westpac New Zealand’s ESG Credit Risk Policy details the overall approach to managing ESG risks in the credit risk process for applicable

transactions.

Note 13 Credit risk management (continued)
13.2 Credit risk ratings system

The principal objective of the credit risk rating system is to reliably assess the credit risk to which the NZ Banking Group is exposed. The NZ

Banking Group has two main approaches to this assessment:

Transaction-managed customers

Transaction managed customers are generally customers with business lending exposures. They are individually assigned a CRG, corresponding to

their expected PD. Each facility is assigned an LGD. The NZ Banking Group’s risk rating system has a tiered scale of risk grades for both non-

defaulted customers and defaulted customers. Non-defaulted CRGs are mapped to Moody's and S&P external senior ranking unsecured ratings.

The following table shows the NZ Banking Group’s high level CRGs for transaction-managed portfolios mapped to the NZ Banking Group’s credit

quality disclosure categories and to their corresponding external rating.

WeakEWatchlist

FSpecial Mention

GSubstandard/Default

HDoubtful/Default

Program-managed portfolio

The program-managed portfolio generally includes retail products such as mortgages, personal lending (including credit cards) and certain SME

lending. These credit exposures are grouped into pools of similar risk based on analysis of characteristics that have historically predicted the

likelihood of default, and a PD is assigned relative to the credit exposure's pool. The exposure is then assigned to strong, good/satisfactory or weak

by benchmarking that PD against the NZ Banking Group's CRGs, which are in turn mapped to external ratings as per the above table. In addition,

any program-managed exposures that are past due are classified as weak.

13.3 Credit risk concentrations and maximum exposure to credit risk

Credit risk is concentrated when a number of counterparties are engaged in similar activities, or have similar economic characteristics, and thus

may be similarly affected by changes in economic or other conditions.

The NZ Banking Group monitors its credit portfolio to allow it to manage risk concentrations and rebalance the portfolio.

Individual customers or groups of related customers

The NZ Banking Group has large exposure limits governing the aggregate size of credit exposure normally acceptable to individual customers and

groups of related customers. These limits are tiered by CRG.

Specific industries

Exposures to businesses, governments and other financial institutions are classified into a number of industry clusters based on related ANZSIC

codes and are monitored against the NZ Banking Group’s industry risk appetite limits.

Individual countries

The NZ Banking Group has limits governing risks related to individual countries, such as political situations, government policies and economic

conditions that may adversely affect either a customer’s ability to meet its obligations to the NZ Banking Group, or the NZ Banking Group’s ability

to realise its assets in a particular country.

Westpac Banking Corporation - New Zealand Banking Group33

Note 13 Credit risk management (continued)
13.5 Credit risk mitigation, collateral and other credit enhancements

The NZ Banking Group uses a variety of techniques to reduce the credit risk arising from its lending activities.

This includes the NZ Banking Group having processes in place to ensure that it has direct, irrevocable and unconditional recourse to collateral and

other credit enhancements through obtaining legally enforceable documentation.

Collateral

The table below describes the nature of collateral or security held for each relevant class of financial asset:

Loans – residential mortgages

1

Housing loans are secured by a mortgage over property and additional security may take the

form of guarantees and deposits.

Loans – other retail

1

Personal lending (including credit cards and overdrafts) is predominantly unsecured. Where

security is taken, it is restricted to eligible motor vehicles, caravans, campers, motor homes

and boats.

SME loans may be secured, partially secured or unsecured. Security is typically taken by way

of a mortgage over property and/or a general security agreement over business assets or

other assets.

Loans – corporate

1

Business loans may be secured, partially secured or unsecured. Security is typically taken by

way of a mortgage over property and/or a general security agreement over business assets

or other assets.

Other security such as guarantees or standby letters of credit may also be taken as collateral,

if appropriate.

Trading securities and financial assets

measured at FVIS and derivative financial

instruments

These exposures are carried at fair value which reflects the credit risk.

For trading securities, no collateral is sought directly from the issuer or counterparty;

however this may be implicit in the terms of the instrument (such as an asset-backed

security). The terms of debt securities may include collateralisation.

Master netting agreements are typically used to enable the effects of derivative assets and

derivative liabilities with the same counterparty to be offset when measuring these

exposures. Additionally, collateralisation agreements are also typically entered into with

major institutional counterparties to avoid the potential build-up of excessive mark-to-

market positions. Derivative transactions are increasingly being cleared through central

clearers.

1

This includes collateral held in relation to associated credit commitments.

Notes to the financial statements

34Westpac Banking Corporation - New Zealand Banking Group

Note 13 Credit risk management (continued)
Management of risk mitigation

The NZ Banking Group mitigates credit risk through controls covering:

Collateral and valuation

management

The Overseas Bank manages collateral under collateralisation agreements centrally for all branches of

the Overseas Bank and Westpac New Zealand.

The NZ Banking Group revalues collateral related to financial markets positions on a daily basis and

has formal processes in place to promptly call for collateral top-ups, if required. These processes

include margining for non-centrally cleared customer derivatives where required under APRA

Prudential Standard CPS226. The collateralisation arrangements are documented via the Credit

Support Annex of the International Swaps and Derivatives Association dealing agreements and Global

Master Repurchase Agreements for repurchase transactions.

The estimated realisable value of collateral held in support of loans is based on a combination of:

●formal valuations currently held for such collateral; and

●management’s assessment of the estimated realisable value of all collateral held.

This analysis also takes into consideration any other relevant knowledge available to management at

the time. Updated valuations are obtained when appropriate.

Other credit enhancements

The NZ Banking Group only recognises guarantees, standby letters of credit, or credit derivative

protection from entities meeting minimum eligibility requirements (provided they are not related to

the entity with which the NZ Banking Group has a credit exposure) including but not limited to:

●Sovereign;

●Australia and New Zealand public sector;

●Authorised deposit-taking institutions and overseas banks with a minimum risk grade equivalent

of A3 / A-; and

●Other entities with a minimum risk grade equivalent of A3 / A-.

Credit Portfolio Management manages the NZ Banking Group’s corporate, sovereign and bank credit

portfolios through monitoring the exposure and any offsetting hedge positions.

Credit Portfolio Management purchases credit protection from entities that meet minimum eligibility

requirements.

Offsetting

Creditworthy customers domiciled in New Zealand may enter into formal agreements with the NZ

Banking Group, permitting the NZ Banking Group to set-off gross credit and debit balances in their

nominated accounts. Cross-border set-offs are not permitted.

Close-out netting is undertaken with counterparties with whom the NZ Banking Group has entered into

a legally enforceable master netting agreement for their off-balance sheet financial market

transactions in the event of default.

Further details of offsetting are provided in Note 25.

Central clearing

The NZ Banking Group increasingly executes derivative transactions through central clearing

counterparties. Central clearing counterparties mitigate risk through stringent membership

requirements, the collection of margin against all trades placed, the default fund, and an explicitly

defined order of priority of payments in the event of default.

Collateral held against loans

The NZ Banking Group analyses the coverage of the loan portfolio which is secured by the collateral that it holds. Coverage is measured as follows:

CoverageSecured loan to collateral value ratio

Fully securedLess than or equal to 100%

Partially securedGreater than 100% but not more than 150%

Unsecured

Greater than 150%, or no security held (e.g. can include credit cards, personal loans, and exposure to highly rated

corporate entities)

Note 14 Deferred tax assets
Accounting policy

Deferred tax accounts for temporary differences between the carrying amounts of assets and liabilities in the financial statements and their

values for taxation purposes.

Deferred tax is determined using the enacted or substantively enacted tax rates and laws which are expected to apply when the assets will be

realised or the liabilities settled.

Deferred tax assets and liabilities have been offset where they relate to the same taxation authority, the same taxable entity or group and where

there is a legal right and intention to settle on a net basis.

Deferred tax assets are recognised to the extent that it is probable that future taxable profits will be available to utilise the assets.

Deferred tax is not recognised for the following temporary differences:

●the initial recognition of assets or liabilities in a transaction that is not a business combination and that affects neither the accounting nor

taxable profit or loss; and

●the initial recognition of goodwill in a business combination.

Note 15 Intangible assets
Accounting policy

Indefinite life intangible assets

Goodwill

Goodwill acquired in a business combination is initially measured at cost, being the excess of the consideration paid, over the net fair value of

the identifiable assets, liabilities and contingent liabilities acquired.

Subsequently, goodwill is not amortised but rather tested for impairment. Impairment is tested at least annually or whenever there is an

indication of impairment. An impairment charge is recognised when a CGU’s carrying value exceeds its recoverable amount. Recoverable

amount means the higher of the CGU’s fair value less costs to sell and its value-in-use.

The NZ Banking Group’s CGUs represent the smallest identifiable group of assets that generate cash inflows that are largely independent of the

cash inflows from other assets or group of assets. They reflect the level at which the NZ Banking Group monitors and manages its operations.

Finite life intangible assets

Finite life intangibles such as computer software which are recognised initially at cost and subsequently at amortised cost less any impairment.

Impairment

When assessing impairment of intangible assets, judgement is needed to determine the appropriate cash flows and discount rates to be applied

to the calculations. The assumptions applied to the value-in-use calculations are outlined below.

Impairment testing and results

Impairment testing is performed at least once a year, or whenever there is an indication of impairment, by comparing the recoverable amount of

each CGU with the carrying amount. The primary test for the recoverable amount is determined based on value-in-use which refers to the present

value of expected cash flows under its current use.

Impairment testing in the current year confirmed that the NZ Banking Group continues to have considerable headroom when determining whether

goodwill is recoverable, and no impairment should be recognised.

Assumptions used in recoverable amount calculations

The assumptions made for goodwill impairment testing for each relevant significant CGU are provided in the following table and are based on past

experience and management’s expectations for the future. In the current year and given the present economic environment, the NZ Banking

Group has reassessed these assumptions and revised them where necessary in order to provide a reasonable estimate of the value-in-use of the

CGUs.

Note 15 Intangible assets (continued)
The cashflows used are based on management approved forecasts. These forecasts utilise information about current and future economic

conditions, observable historical information and management expectations of future business performance. The terminal value growth rate

represents the growth rate applied to extrapolate cash flows beyond the forecast period and reflects the midpoint of the Reserve Bank’s inflation

target over the medium term.

There are no reasonably possible changes in assumptions for any significant CGU that would result in an indication of impairment or have a

material impact on the NZ Banking Group’s reported results.

Note 16 Deposits and other borrowings

Accounting policy

Deposits and other borrowings are initially recognised at fair value and subsequently either measured at amortised cost using the effective

interest method or at fair value.

Deposits and other borrowings are designated at fair value if they are managed on a fair value basis, reduce or eliminate an accounting

mismatch, or contain an embedded derivative.

Where they are measured at fair value, any changes in fair value (except those due to changes in credit risk) are recognised in the income

statement. The change in the fair value that is attributable to changes in credit risk is recognised in OCI except where it would create an

accounting mismatch, in which case it is also recognised in the income statement.

Interest expense incurred for deposits and other borrowings at amortised cost is recognised in net interest income using the effective interest

method.

Non-interest bearing relates to instruments which do not carry an entitlement to interest.

Note 17 Other financial liabilities

Accounting policy

Other financial liabilities include liabilities measured at amortised cost as well as liabilities which are measured at FVIS. Financial liabilities

measured at FVIS include:

●trading liabilities (i.e. securities sold short); and

●liabilities designated at FVIS (i.e. certain repurchase agreements).

Repurchase agreements

Where securities are sold subject to an agreement to repurchase at a predetermined price, they remain recognised on the balance sheet in their

original category (i.e. trading securities and financial assets measured at FVIS or investment securities).

The cash consideration received is recognised as a liability (repurchase agreements). Repurchase agreements are designated at fair value where

this eliminates or significantly reduces an accounting mismatch, or they are part of a group of instruments that are managed on a fair value

basis. Otherwise they are measured on an amortised cost basis.

Where a repurchase agreement is designated at fair value, any changes in fair value (except those due to change in credit risk) are recognised in

the income statement as they arise. The change in fair value that is attributable to credit risk is recognised in OCI except where it would create

an accounting mismatch in which case it is also recognised in the income statement.

Debt issues are bonds, notes and commercial paper that have been issued by the NZ Banking Group.

Debt issues are initially measured at fair value and subsequently either measured at amortised cost using the effective interest method or at fair

value.

Debt issues are designated at fair value if they reduce or eliminate an accounting mismatch or contain an embedded derivative.

Where they are measured at fair value, any changes in fair value (except those due to changes in credit risk) are recognised in the income

statement. The change in the fair value that is attributable to changes in credit risk is recognised in OCI except where it would create an

accounting mismatch, in which case it is also recognised in the income statement.

Interest expense incurred is recognised within net interest income using the effective interest method.

Note 19 Provisions
Accounting policy

Provisions are recognised for present obligations arising from past events where a payment (or other economic transfer) is likely to be necessary

to settle the obligation and can be reliably estimated.

Employee benefits – annual leave and other employee benefits

The provision for annual leave and other employee benefits (including long service leave, wages and salaries, inclusive of non-monetary benefits,

and any associated on-costs (e.g. payroll tax)) is calculated based on expected payments.

Provision for ECL on credit commitments

The NZ Banking Group is committed to provide facilities and guarantees as explained in Note 26. If it is probable that a facility will be drawn and

the resulting asset will be less than the drawn amount then a provision for impairment is recognised. The provision for impairment is calculated

using the same methodology as the provision for ECL (refer to Note 12).

Compliance, regulation and remediation provisions

The compliance, regulation and remediation provisions relate to matters pertaining to the provision of services to our customers identified both

as a result of regulatory action and internal reviews. An assessment of the likely cost to the NZ Banking Group of these matters (including

applicable customer refunds) is made on a case-by-case basis and specific provisions are made where appropriate.

The movement in the provision for ECL on credit commitments is presented on a net basis as either an addition for an increase or reversal of unutilised provision for

a decrease. Refer to Note 12 for further details.

Compliance, regulation and remediation provisions

The compliance, regulation and remediation provisions relate to matters pertaining to the provision of services to our customers identified as a

result of regulatory action and internal reviews, including the NZ Banking Group’s review of processes for some products relating to the

requirements of the CCCFA.

All potential claims and other liabilities are assessed on a case-by-case basis. A provision has been recognised where the NZ Banking Group has

conducted an assessment which determines the likelihood of loss as probable and where its potential loss can be reliably estimated.

A number of different estimates and judgements have been applied in measuring the provision at 30 September 2025, including the number of

impacted customers, the refund per customer and the additional costs to run the remediation programme. It is possible that the actual outcome

for these matters may differ from the assumptions used in estimating the provision. Remediation processes may change over time as further facts

emerge and such changes could result in a change to the final exposure.

Where a provision has not been recognised, a contingent liability may exist. Refer to Note 26 for further details on contingent liabilities.

Note 20 Loan capital
Accounting policy

Loan capital is comprised of debt instruments which qualify for inclusion as regulatory capital under either the Reserve Bank BPRs or, in relation

to the Overseas Bank, the APRA Prudential Standards. Loan capital is initially measured at fair value and subsequently measured at amortised

cost using the effective interest method. Interest expense incurred is recognised in net interest income.

The USD AT1 securities were issued by the Overseas Bank acting through its NZ Branch.

2

Fixed interest rate of 5.00% p.a., until, but excluding 21 September 2027 (the ‘first reset date’). Every fifth anniversary thereafter is a reset date. If the USD AT1

securities are not redeemed, converted or written-off by the first reset date, the interest rate from, and including, each reset date thereafter to, but excluding the

next succeeding reset date, will be a fixed rate per annum equal to the prevailing 5-year USD mid-market swap rate plus 2.888% p.a.

Interest payable

Semi-annual interest payments on the USD AT1 securities are at the absolute discretion of the Overseas Bank and will only be paid if the payment

conditions are satisfied, including that the interest payment will not result in a breach of the Overseas Bank’s capital requirements under APRA’s

prudential standards; not result in the Overseas Bank becoming, or being likely to become, insolvent; and if APRA does not object to the payment.

Broadly, if for any reason an interest payment has not been paid in full on the relevant payment date, the Overseas Bank must not determine or

pay any dividends on Overseas Bank ordinary shares or undertake a discretionary buy-back or capital reduction of Overseas Bank ordinary shares,

unless the unpaid interest is paid in full within 20 business days of the relevant payment date or in certain other circumstances.

Redemption

The Overseas Bank may redeem all (but not some) USD AT1 securities on 21 September 2027 and every fifth anniversary thereafter, or for certain

taxation or regulatory reasons, subject to APRA’s prior written approval.

Note 20 Loan capital (continued)
Conversion

If a capital trigger event or non-viability trigger event occurs, the Overseas Bank must convert some or all of the USD AT1 securities into a variable

number of Overseas Bank ordinary shares calculated using the formula described in the terms of the USD AT1 securities but subject to a maximum

conversion number. The conversion number of the Overseas Bank’s ordinary shares will be calculated using the outstanding principal amount of

each USD AT1 security translated into Australian dollars and the Overseas Bank ordinary share price determined over the five business day period

prior to the capital trigger event date or non-viability trigger event date and includes a 1% discount. The maximum conversion number is

calculated using the outstanding principal amount of each USD AT1 security translated into Australian dollars at the time of issue and the Overseas

Bank share price which is broadly equivalent to 20% of the Overseas Bank ordinary share price at the time of issue of the USD AT1 securities.

A capital trigger event occurs when the Overseas Bank determines, or APRA notifies the Overseas Bank in writing that it believes, the Overseas

Bank’s Common Equity Tier 1 capital ratio is equal to or less than 5.125% (on a level 1 or level 2 basis, refer to Note 30). A non-viability trigger event

will occur where APRA notifies the Overseas Bank in writing that it believes conversion of all or some USD AT1 securities (or conversion or write-

down of relevant capital instruments of the Overseas Banking Group), or public sector injection of capital (or equivalent support), in each case is

necessary because without it, the Overseas Bank would become non-viable. No conversion conditions apply in these circumstances.

If conversion of the USD AT1 securities does not occur within five business days, holders’ rights in relation to the USD AT1 securities will be

immediately and irrevocably terminated.

The subordinated notes were issued by Westpac New Zealand for the purposes of the Reserve Bank's capital requirements, however they do not constitute Tier 2

capital for the Overseas Banking Group as the terms of the Tier 2 capital do not satisfy APRA's capital requirements.

Common features of subordinated notes

Interest payable

Quarterly interest payments on the subordinated notes are subject to Westpac New Zealand being solvent at the time of, and immediately

following, the interest payment.

Early redemption

Westpac New Zealand may elect to redeem all or some of the 2022 or 2023 subordinated notes for their face value together with accrued interest

(if any) on an optional redemption date for the series specified above, subject to the Reserve Bank’s prior written approval. Early redemption of all

of the 2022 or 2023 subordinated notes for certain tax or regulatory reasons is permitted on an interest payment date subject to the Reserve

Bank’s prior written approval.

Notes to the financial statements

48Westpac Banking Corporation - New Zealand Banking Group

Note 23 Derivative financial instruments
Accounting policy

Derivative financial instruments are instruments whose values are derived from the value of an underlying asset, reference rate or index and

include forwards, futures, swaps and options. Derivatives with related parties are included in due from/due to related entities.

The NZ Banking Group uses derivative financial instruments for meeting customers’ needs; our ALM activities, and undertaking market making

and positioning activities.

Trading derivatives

Derivatives which are used in our ALM activities but are not designated into a hedge accounting relationship are considered economic hedges.

These derivatives, along with derivatives used for meeting customers’ needs and undertaking market making and positioning activities are

measured at FVIS and are disclosed as trading derivatives in this note.

Hedging derivatives

Hedging derivatives are those which are used in our ALM activities and have also been designated into one of two hedge accounting

relationships: fair value hedge; or cash flow hedge. These derivatives are measured at fair value. These hedge designations and the associated

accounting treatment are detailed below.

For more details regarding the NZ Banking Group’s ALM activities, refer to Note 31.

Fair value hedges

Fair value hedges are used to hedge the exposure to changes in the fair value of an asset or liability.

Changes in the fair value of derivatives and the hedged asset or liability in fair value hedges are recognised in non-interest income. The carrying

value of the hedged asset or liability is adjusted for the changes in fair value related to the hedged risk.

If a hedge is discontinued, any fair value adjustments to the carrying value of the asset or liability are amortised to net interest income over the

period to maturity. If the asset or liability is sold, any unamortised adjustment is immediately recognised in net interest income.

Cash flow hedges

Cash flow hedges are used to hedge the exposure to variability of cash flows attributable to an asset, liability or future forecast transaction.

For effective hedges, changes in the fair value of derivatives are recognised in the cash flow hedge reserve through OCI and subsequently

recognised in net interest income when the cash flows attributable to the asset or liability that was hedged impact the income statement.

For hedges with some ineffectiveness, the changes in the fair value of the derivatives relating to the ineffective portion are immediately

recognised in non-interest income.

If a hedge is discontinued, any cumulative gain or loss remains in OCI. It is amortised to net interest income over the period which the asset or

liability that was hedged also impacts the income statement.

If a hedge of a forecast transaction is no longer expected to occur, any cumulative gain or loss in OCI is immediately recognised in net interest

income.

Notes to the financial statements

50Westpac Banking Corporation - New Zealand Banking Group

Note 23 Derivative financial instruments (continued)
Hedge accounting

The NZ Banking Group designates derivatives into hedge accounting relationships in order to manage the volatility in earnings and capital that

would otherwise arise from interest rate and FX risks that may result from differences in the accounting treatment of derivatives and underlying

exposures. These hedge accounting relationships and the risks they are used to hedge are described below.

The NZ Banking Group enters into one-to-one hedge relationships to manage specific exposures where the terms of the hedged item significantly

match the terms of the hedging instrument. The NZ Banking Group also uses dynamic hedge accounting where the hedged items are part of a

portfolio of assets and/or liabilities that frequently change. In this hedging strategy, the exposure being hedged and the hedging instruments may

change frequently rather than there being a one-to-one hedge accounting relationship for a specific exposure.

Fair value hedges

Interest rate risk

The NZ Banking Group hedges its interest rate risk to reduce exposure to changes in fair value due to interest rate fluctuations over the hedging

period. Interest rate risk arising from fixed rate debt issuances and fixed rate bonds classified as investment securities at FVOCI is hedged with

single currency fixed to floating interest rate derivatives. The NZ Banking Group also hedges its benchmark interest rate risk from fixed rate foreign

currency denominated debt issuances using cross currency swaps. In applying fair value hedge accounting the NZ Banking Group primarily uses

one-to-one hedge accounting to manage specific exposures.

The NZ Banking Group also uses a dynamic hedge accounting strategy for fair value portfolio hedge accounting of some fixed rate mortgages to

reduce exposure to changes in fair value due to interest rate fluctuations over the hedging period. These fixed rate mortgages are allocated to

time buckets based on their expected repricing dates and the fixed-to-floating interest rate derivatives are designated according to the capacity in

the relevant time buckets.

The NZ Banking Group hedges the benchmark interest rate which generally represents the most significant component of the changes in fair value.

The benchmark interest rate is a component of interest rate risk that is observable in the relevant financial markets, for example, Secured

Overnight Financing Rate (‘SOFR’) for USD interest rates and BKBM for NZD interest rates. Ineffectiveness may arise from timing or discounting

differences on repricing between the hedged item and the derivative. For portfolio hedge accounting, ineffectiveness also arises from prepayment

risk (i.e. the difference between actual and expected prepayment of loans). In order to manage the ineffectiveness from early repayments and

accommodate new originations the portfolio hedges are de-designated and redesignated periodically.

Cash flow hedges

Interest rate risk

The NZ Banking Group’s exposure to the volatility of interest cash flows from customer deposits and loans is hedged with interest rate derivatives

using a dynamic hedge accounting strategy called macro cash flow hedges. Customer deposits and loans are allocated to time buckets based on

their expected repricing dates. The interest rate derivatives are designated according to the gross asset or gross liability positions for the relevant

time buckets. The NZ Banking Group hedges the benchmark interest rate which generally represents the most significant component of the

changes in fair value. The benchmark interest rate is a component of interest rate risk that is observable in the relevant financial markets, for

example, SOFR for USD interest rates and BKBM for NZD interest rates. Ineffectiveness may arise from timing or discounting differences on

repricing between the hedged item and the interest rate derivative. Ineffectiveness also arises if the notional values of the interest rate derivatives

exceed the aggregate notional exposure for the relevant time buckets. The hedge accounting relationship is reviewed on a monthly basis and the

hedging relationships are de-designated and redesignated if necessary.

FX risk

The NZ Banking Group’s exposure to foreign currency principal and credit margin cash flows from fixed rate foreign currency debt issuances is

hedged through the use of cross currency derivatives in a one-to-one hedging relationship to manage the changes between the foreign currency

and NZD. In addition, for floating rate foreign currency debt issuances, the NZ Banking Group hedges from foreign floating to NZD floating interest

rates. Ineffectiveness may arise from timing or discounting differences on repricing between the hedged item and the cross currency derivative.

Economic hedges

As part of the NZ Banking Group’s ALM activities, economic hedges may be entered into to hedge long-term funding transactions for risk

management purposes. These hedges do not qualify for hedge accounting and are therefore not included in the hedging instrument disclosures

below.

Hedge effectiveness

Hedge effectiveness is tested prospectively at inception and during the lifetime of hedge relationships. For one-to-one hedge relationships this

testing uses a qualitative assessment of matched terms where the critical terms of the derivatives used as the hedging instrument match the

terms of the hedged item. In addition, a quantitative effectiveness test is performed for all hedges which could include regression analysis, dollar

offset and/or sensitivity analysis.

Retrospective testing is also performed to determine whether the hedge relationship remains highly effective so that hedge accounting can

continue to be applied and also to determine any ineffectiveness. These tests are performed using regression analysis and the dollar offset

method.

Note 24 Fair values of financial assets and financial liabilities
Accounting policy

The fair value of a financial instrument is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction

between market participants at the measurement date.

On initial recognition, the transaction price generally represents the fair value of the financial instrument unless there is observable information

from an active market to the contrary. Where unobservable information is used, the difference between the transaction price and the fair value

(day one profit or loss) is recognised in the income statement over the life of the instrument or when the inputs become observable.

Critical accounting assumptions and estimates

The majority of valuation models used by the NZ Banking Group employ only observable market data as inputs. However, for certain financial

instruments, data may be employed which is not readily observable in current markets.

The availability of observable inputs is influenced by factors such as:

●product type;

●depth of market activity;

●maturity of market models; and

●complexity of the transaction.

Where unobservable market data is used, more judgement is required to determine fair value. The significance of these judgements depends on

the significance of the unobservable input to the overall valuation. Unobservable inputs are generally derived from other relevant market data

and adjusted against:

●standard industry practice;

●economic models; and

●observed transaction prices.

In order to determine a reliable fair value for a financial instrument, management may apply adjustments to the techniques previously

described.

These adjustments reflect the NZ Banking Group’s assessment of factors that market participants would consider in setting the fair value.

These adjustments incorporate bid/offer spreads, credit valuation adjustments and funding valuation adjustments.

Fair Valuation Control Framework

The NZ Banking Group uses a Fair Valuation Control Framework where the fair value is either determined or validated by a function independent of

the transaction. This framework formalises the policies and procedures used to achieve compliance with relevant accounting, industry and

regulatory standards. The framework includes specific controls relating to:

●the revaluation of financial instruments;

●independent price verification;

●fair value adjustments; and

●financial reporting.

A key element of the framework is the Revaluation Committee, comprising senior valuation specialists from within the Overseas Banking Group.

The Revaluation Committee reviews the application of the agreed policies and procedures to assess that a fair value measurement basis has been

applied.

The method of determining fair value differs depending on the information available.

Fair value hierarchy

A financial instrument’s categorisation within the valuation hierarchy is based on the lowest level input that is significant to the fair value

measurement.

The NZ Banking Group categorises all fair value instruments according to the hierarchy described below.

Valuation techniques

The NZ Banking Group applies market accepted valuation techniques in determining the fair valuation of over-the-counter derivatives. This

includes credit valuation adjustments and funding valuation adjustments, which incorporate credit risk and funding costs and benefits that arise in

relation to uncollateralised derivative positions, respectively.

The specific valuation techniques, the observability of the inputs used in valuation models and the subsequent classification for each significant

product category are outlined as follows:

Analysis of movements between fair value hierarchy levels

For the year ended 30 September 2025, the NZ Banking Group has refined its approach and applied a more granular assessment with additional

metrics sourced from its independent pricing services to complete the fair value level classification of New Zealand Government treasury bills. As

a result, $697 million of these trading securities and financial assets measured at FVIS have been transferred from Level 1 to Level 2. Transfers in

and transfers out are reported using the end of period fair values. There were no other material transfers between levels of the fair value hierarchy

during the year (30 September 2024: no material transfers between levels).

Note 24 Fair values of financial assets and financial liabilities (continued)
Financial instruments not measured at fair value

For financial instruments not measured at fair value on a recurring basis, fair value has been derived as follows:

InstrumentValuation

Loans

Where available, the fair value of loans is based on observable market transactions; otherwise fair value is

estimated using discounted cash flow models. For variable rate loans, the discount rate used is the current effective

interest rate. The discount rate applied for fixed rate loans reflects the market rate for the maturity of the loan and

the creditworthiness of the borrower.

Deposits and other

borrowings

Fair values of deposit liabilities payable on demand (interest free, interest bearing and savings deposits)

approximate their carrying value. Fair values for term deposits are estimated using discounted cash flows, applying

market rates offered for deposits of similar remaining maturities.

Due to related entities

The carrying value of due to related entities approximates the fair value. These items are either short-term in nature

or re-price frequently, and are of a high credit rating.

Debt issues and

loan capital

The fair values of these instruments are calculated based on quoted market prices, where available. Where quoted

market prices are not available, fair values are calculated using a discounted cashflow model. The discount rates

applied reflect the terms of the instruments and the timing of the estimated cash flows and are adjusted for any

changes in the NZ Banking Group’s credit spreads.

All other financial

assets and financial

liabilities

For all other financial assets and financial liabilities, the carrying value approximates the fair value. These items are

Note 25 Offsetting financial assets and financial liabilities

Accounting policy

Financial assets and financial liabilities are presented net on the balance sheet when the NZ Banking Group has a legally enforceable right to

offset them in all circumstances and there is an intention to settle the asset and liability on a net basis, or to realise the asset and settle the

liability simultaneously. The gross assets and liabilities behind the net amounts reported on the balance sheet are disclosed in the following

table.

Some of the NZ Banking Group’s offsetting arrangements are not enforceable in all circumstances. The amounts in the tables below may not tie

back to the balance sheet if there are balances which are not subject to offsetting or enforceable netting arrangements. The amounts presented in

this note do not represent the credit risk exposure of the NZ Banking Group. Refer to Note 13 for information on credit risk management. The

offsetting and collateral arrangements and other credit risk mitigation strategies used by the NZ Banking Group are further explained in the

‘Management of risk mitigation’ section under Note 13.5.

$392 million (30 September 2024: $183 million) of derivative financial assets and $94 million (30 September 2024: $258 million) of derivative financial liabilities are

not subject to enforceable netting arrangements.

Other recognised financial instruments

These financial assets and financial liabilities are subject to master netting agreements which are not enforceable in all circumstances, so they are

recognised gross on the balance sheet. The offsetting rights of the master netting arrangements can only be enforced if a predetermined event

occurs in the future, such as a counterparty defaulting.

Cash collateral and financial instrument collateral

These amounts are received or pledged under master netting arrangements against the gross amounts of assets and liabilities. Financial

instrument collateral typically comprises securities which can be readily liquidated in the event of counterparty default. The offsetting rights of the

master netting arrangement can only be enforced if a predetermined event occurs in the future, such as a counterparty defaulting.

Note 26 Credit related commitments, contingent assets and contingent liabilities
Accounting policy

Undrawn credit commitments

The NZ Banking Group enters into various arrangements with customers which are only recognised on the balance sheet when called upon.

These arrangements include commitments to extend credit, bill endorsements, financial guarantees, standby letters of credit and underwriting

facilities.

Contingent assets

Contingent assets are possible assets whose existence will be confirmed only by uncertain future events. Contingent assets are not recognised

on the balance sheet but are disclosed if an inflow of economic benefits is probable.

Contingent liabilities

Contingent liabilities are possible obligations whose existence will be confirmed only by uncertain future events, and present obligations where

the transfer of economic resources is not probable or cannot be reliably measured. Contingent liabilities are not recognised on the balance

sheet but are disclosed unless the outflow of economic resources is remote.

Undrawn credit commitments

Undrawn credit commitments expose the NZ Banking Group to liquidity risk when called upon and also to credit risk if the customer fails to repay

the amounts owed at the due date. The maximum exposure to credit loss is the contractual or notional amount of the instruments disclosed

below. Some of the arrangements can be cancelled by the NZ Banking Group at any time. The actual liquidity and credit risk exposure varies in line

with drawings and may be less than the amounts disclosed. The NZ Banking Group uses the same credit policies when entering into these

arrangements as it does for on-balance sheet instruments. Refer to Note 13 and Note 31 for further details on credit risk management and liquidity

risk.

Standby letters of credit and guarantees are undertakings to pay, against presentation of documents, an obligation in the event of a default by a customer.

Guarantees are unconditional undertakings given to support the obligations of a customer to third parties. The NZ Banking Group may hold cash as collateral for

certain guarantees issued.

2

Commitments to extend credit include all obligations on the part of the NZ Banking Group to provide credit facilities. As facilities may expire without being drawn

upon, the notional amounts do not necessarily reflect future cash requirements.

3

In addition to the commitments disclosed above, there is $1,358 million (30 September 2024: $964 million) of exposure to credit risk relating to credit exposures

offered and accepted but still revocable, which represent part of the Banking Group's maximum exposure to credit risk.

4

Comparatives have been revised to remove credit exposures offered and accepted but still revocable.

Contingent assets

The NZ Banking Group enters into various arrangements with customers that constitute contingent assets. If a specified contingent event occurs,

these commitments will be called upon and recognised on the balance sheet as loans.

Contingent liabilities

The NZ Banking Group has contingent risks and liabilities arising from the conduct of its business, including: actual and potential disputes, claims,

legal proceedings, investigations, inquiries and reviews (formal and informal) carried out by regulatory authorities (including into the NZ Banking

Group's processes for some products relating to the requirements of the CCCFA); and internal investigations and reviews.

The scope of reviews (internal and external), investigations and inquiries, including those relating to the requirements of the CCCFA, can be wide-

ranging and can result in litigation (including class action proceedings and enforcement proceedings), fines and penalties, customer remediation

and/or other sanctions and reputational damage.

All potential claims and other liabilities are assessed on a case-by-case basis. A provision will be recognised where the NZ Banking Group has

conducted an assessment which determines the likelihood of loss as probable and where its potential loss can be reliably estimated. A contingent

liability exists in respect of actual or potential claims where the likely loss is not assessed as probable, where the law is uncertain or, in rare

circumstances, where the outflow of resources cannot be reliably estimated.

Note 27 Segment reporting
Accounting policy

Operating segments are presented on a basis that is consistent with information provided internally to the NZ Banking Group’s chief operating

decision-maker and reflect the management of the business, rather than the legal structure of the NZ Banking Group. The chief operating

decision-maker is the person or group that allocates resources to and assesses the performance of the operating segments of an entity. The NZ

Banking Group has determined that the NZ Banking Group executive team is its chief operating decision-maker.

Inter-segment revenue and costs are eliminated at head office. Income and expenses directly associated with each segment are included in

determining business segment performance.

The NZ Banking Group operates predominantly in the Consumer Banking and Wealth, Institutional and Business Banking and Financial Markets,

International Trade and Payments sectors within New Zealand. On this basis, no geographical segment reporting is provided.

The operating segment results have been presented on a management reporting basis and consequently internal charges and transfer pricing

adjustments have been reflected in the performance of each operating segment. Intersegment pricing is determined on a cost recovery basis.

The NZ Banking Group does not rely on any single major customer for its revenue base.

Segment comparative information for the year ended 30 September 2024 has been revised to align to the current year's basis for reporting, and is

consistent with the information provided internally to the NZ Banking Group's chief operating decision-maker.

The NZ Banking Group’s operating segments are defined by the customers they serve and the services they provide. The NZ Banking Group has

identified the following main operating segments:

●Consumer Banking and Wealth provides financial services predominantly for individuals;

●Institutional and Business Banking provides a broad range of financial services for small to medium enterprise, corporate, property finance,

agricultural, institutional and government customers; and

●Financial Markets provides foreign exchange, interest rate derivatives, fixed interest and debt securities, commodities, carbon and energy

capabilities. International Trade and Payments provide international trade solutions, payments products and services to consumer,

business and institutional customers.

Other primarily represents:

●business units that do not meet the definition of a reportable operating segment under NZ IFRS 8 Operating Segments;

●elimination entries on consolidation/aggregation of the results, assets and liabilities of the NZ Banking Group’s controlled entities in the

preparation of the aggregated financial statements of the NZ Banking Group; and

●results of certain business units excluded for management reporting purposes, but included within the aggregated financial statements of

the NZ Banking Group for statutory financial reporting purposes.

62Westpac Banking Corporation - New Zealand Banking Group

Note 28 Securitisation, covered bonds and other transferred assets
The NZ Banking Group enters into transactions in the normal course of business by which financial assets, or an interest in such assets or

cashflows arising from such assets, are transferred to counterparties or structured entities. Depending on the circumstances, these transfers may

result in derecognition of the assets in their entirety, partial derecognition or no derecognition of the asset. For the NZ Banking Group’s accounting

policy on derecognition of financial assets, refer to Note 1.

Securitisation

Securitisation is the process of selling a group of assets (or an interest in the assets or the cashflow arising from the assets) to a special purpose

entity which then issues interest bearing debt securities for funding purposes.

Securitisation of its own assets is used by the NZ Banking Group as a funding and liquidity tool.

In October 2008, the NZ Banking Group set up WNZSL as a structured entity for the purpose of structuring assets that are eligible for repurchase

agreements with the Reserve Bank as part of Westpac New Zealand’s internal residential mortgage-backed securitisation programme.

Under the internal residential mortgage-backed securitisation programme, Westpac New Zealand periodically sells the rights (but not the

obligations) under eligible housing loans to WNZSL. The purchase by WNZSL of the housing loans is funded by the proceeds of the issuance of

RMBS.

Westpac New Zealand is obliged to repurchase any housing loan sold to and held by WNZSL where the housing loan does not meet the eligibility

criteria of the programme. It is not envisaged that any liability resulting in material loss to the NZ Banking Group will arise from these obligations.

Covered bonds

The NZ Banking Group has a covered bond programme under which it may issue bonds (Covered Bonds). From time to time, the NZ Banking

Group transfers, via assignment, housing loans originated by Westpac New Zealand to a bankruptcy remote structured entity, WNZCBL. WNZCBL

is a special purpose entity which holds the rights to, but not the obligations under, the pool of housing loans held by it (the Portfolio). The

payments of all amounts due in respect of the Covered Bonds have been unconditionally guaranteed by Westpac New Zealand. In addition,

WNZCBL (the CB Guarantor) has guaranteed payments of interest and principal under the Covered Bonds pursuant to a financial guarantee which

is secured by WNZCBL granting security over the Portfolio and its other assets. Recourse against the CB Guarantor under its guarantee is limited to

the Portfolio and such assets.

The intercompany loan made by Westpac New Zealand to WNZCBL to fund the initial and all subsequent purchases of eligible housing loans and

the liability representing the intercompany loan from WNZCBL to Westpac New Zealand are fully eliminated in the NZ Banking Group’s financial

statements.

Westpac New Zealand is obliged to repurchase any housing loans sold to and held by WNZCBL (pursuant to Westpac New Zealand’s Global

Covered Bond Programme) in certain circumstances including (but not limited to) where:

●it is discovered that there has been a material breach of a sale warranty (or any such sale warranty is materially untrue);

●the loan becomes materially impaired or is enforced prior to the second monthly covered bond payment date falling after the assignment of

the loan; or

●at the cut-off date relating to the loan, there were arrears of interest and that loan subsequently becomes a delinquent loan prior to the

second monthly covered bond payment date falling after the assignment of the loan.

It is not envisaged that any liability resulting in material loss to the NZ Banking Group will arise from these obligations.

Repurchase agreements

Where securities are sold subject to an agreement to repurchase at a predetermined price, they remain recognised on the balance sheet in their

original category (i.e. trading securities and financial assets measured at FVIS or investment securities). Repurchase agreements are designated at

fair value when they are managed as part of a trading portfolio, otherwise they are measured on an amortised cost basis.

The cash consideration received is recognised as a liability (repurchase agreements). Refer to Note 17 for further details.

The most senior rated securities at 30 September 2025 of $10,670 million (30 September 2024: $13,800 million) qualify as eligible collateral for repurchase

agreements with the Reserve Bank. Westpac New Zealand complies with the Reserve Bank’s guidelines for its overnight reverse repurchase agreement facility and

open market operations, which allows banks in New Zealand to offer RMBS as collateral for the Reserve Bank’s repurchase agreements.

2

The difference between the carrying values of the covered bonds and the assets pledged allows for the immediate issuance of additional covered bonds if required.

These additional assets can be repurchased by Westpac New Zealand at its discretion, subject to the conditions set out in the transaction documents. The Portfolio

is comprised of housing loans up to a value of $7,500 million as at 30 September 2025 (30 September 2024: $7,500 million). Over time, the composition of the

Portfolio will include, in addition to housing loans, accrued interest (representing accrued and unpaid interest on the outstanding housing loans) and cash

(representing collections of principal and interest from the underlying housing loans).

Note 29 Structured entities

Accounting policy

Structured entities are generally created to achieve a specific, defined objective and their operations are restricted such as to only purchasing

specific assets. Structured entities are commonly financed by debt or equity securities that are collateralised by and/or indexed to their

underlying assets. The debt and equity securities issued by structured entities may include tranches with varying levels of subordination.

Structured entities are classified as subsidiaries and consolidated if they meet the definition in Note 1. If the NZ Banking Group does not control a

structured entity then it will not be consolidated.

The NZ Banking Group engages in various transactions with both consolidated and unconsolidated structured entities that are mainly involved in

securitisations, asset backed structures and managed funds.

Consolidated structured entities

Securitisation and covered bonds

The NZ Banking Group uses structured entities to securitise its financial assets through the Covered Bond Programme and Westpac New Zealand’s

internal residential mortgage-backed securitisation programme. Refer to Note 28 for further details.

NZ Banking Group managed funds

As disclosed in Note 22, the PIE Funds are consolidated within the financial statements of the NZ Banking Group.

Non-contractual financial support

The NZ Banking Group does not provide non-contractual financial support to these consolidated structured entities.

Notes to the financial statements

64Westpac Banking Corporation - New Zealand Banking Group

Note 29 Structured entities (continued)
Unconsolidated structured entities

The NZ Banking Group has interests in various unconsolidated structured entities including debt instruments, guarantees, liquidity arrangements,

lending, loan commitments, certain derivatives and investment management agreements.

Interests exclude non-complex derivatives (e.g. interest rate swap agreements) and lending to a structured entity with recourse to a wider

operating entity, not just the structured entity.

The NZ Banking Group’s main interests in unconsolidated structured entities, which arise in the normal course of business, are:

Loans and other

credit commitments

The NZ Banking Group lends to unconsolidated structured entities, subject to the NZ Banking Group’s collateral

and credit approval processes, in order to earn interest and fees and commissions income. The structured

entities are mainly securitisation entities.

Investment

management

agreements

The NZ Banking Group manages funds that provide customers with investment opportunities. The NZ Banking

Group also manages superannuation funds for its employees. The NZ Banking Group earns management fee

income which is recognised in non-interest income.

The following table shows the NZ Banking Group’s interests in unconsolidated structured entities and its maximum exposure to loss in relation to

those interests. The maximum exposure does not take into account any collateral or hedges that will reduce the risk of loss.

●For on-balance sheet instruments, including debt instruments in and loans to unconsolidated structured entities, the maximum exposure to

loss is the carrying value; and

●For off-balance sheet instruments, including liquidity facilities and loan and other credit commitments and guarantees, the maximum

exposure to loss is the notional amounts.

Westpac Banking Corporation - New Zealand Banking Group65

Note 30 Capital management
The Overseas Bank is a registered bank in New Zealand and conducts business in New Zealand through the NZ Banking Group. The capital held by

the NZ Banking Group comprises of the head office account, NZ Banking Group equity and loan capital.

Most of the NZ Banking Group’s capital is held in, and managed by Westpac New Zealand. Westpac New Zealand’s Board is responsible for

ensuring that capital adequacy of Westpac New Zealand is maintained and complies with the regulatory capital requirements prescribed by the

Reserve Bank.

There are no current regulatory capital requirements that apply specifically to the NZ Branch or the NZ Banking Group. The Overseas Bank’s Board

is responsible for ensuring that capital adequacy of the Overseas Banking Group and the Overseas Bank is maintained. The NZ Banking Group’s

capital is managed as part of the Overseas Banking Group’s Internal Capital Adequacy Assessment Process. Westpac New Zealand is also required

to maintain its own Internal Capital Adequacy Assessment Process under the Reserve Bank of New Zealand’s capital adequacy requirements.

Under APRA’s Prudential Standards, Australian ADIs, including the Overseas Banking Group and Overseas Bank, are required to maintain minimum

ratios of capital to risk weighted assets, as determined by APRA, which are at least equal to those specified under the Basel III capital framework.

For the calculation of risk weighted assets, the Overseas Banking Group and Overseas Bank are accredited by APRA to apply advanced models.

The Overseas Banking Group and Overseas Bank use the Advanced IRB approach for credit risk, the Standardised Measurement Approach (SMA)

for operational risk and the internal model approach for IRRBB for calculating regulatory capital.

APRA’s Prudential Standards are generally consistent with the International Regulatory Framework for Banks, also known as Basel III, issued by the

Basel Committee on Banking Supervision, except where APRA has exercised certain discretions.

The Overseas Banking Group (excluding entities specifically excluded by APRA regulations), and the Overseas Bank (Extended Licensed Entity as

defined by APRA), exceeded the minimum capital adequacy requirements as specified by APRA as at 30 September 2025.

APRA has announced changes to banks' capital requirements with effect from 1 January 2027, as outlined in Note i. General information

(Unaudited) - Other material matters. This includes changes to CET1, Tier 1, total capital and the leverage ratio.

The Overseas Banking Group's capital management strategy is reviewed on an ongoing basis, including through an Internal Capital Adequacy

Assessment Process. Key considerations include:

●Regulatory capital minimums together with the capital conservation buffer (CCB) and countercyclical capital buffer comprise the Total

Common Equity Tier 1 (CET1) Requirement. The total CET1 requirement is currently at least 10.25% and 10.50% effective 1 January 2027

1

;

●Strategy, business mix and operations and contingency plans;

●Perspectives of external stakeholders including rating agencies as well as equity and debt investors; and

●A stress testing framework that tests our resilience under a range of adverse economic scenarios.

The Overseas Bank Board has determined a target post dividend CET1 capital ratio of above 11.25% in normal operating conditions. This target

includes consideration of APRA's increase in the minimum CET1 ratio of 0.25% to 10.50% effective 1 January 2027 and replaces the previous CET1

capital operating range of between 11.00% and 11.50%.

The table below represents the capital adequacy calculation for the Overseas Banking Group and Overseas Bank as at 30 September 2025 based

on APRA's application of the Basel III capital adequacy framework.

Overseas Banking Group (excluding entities specifically excluded by APRA regulations) comprises the consolidation of the Overseas Bank and its subsidiary entities

except for those entities specifically excluded by APRA regulations for the purposes of measuring capital adequacy (Level 2). The head of the Level 2 group is the

Overseas Bank (Extended Licensed Entity) comprises the Overseas Bank and its subsidiary entities that have been approved by APRA as being part of a single

Extended Licensed Entity for the purpose of measuring capital adequacy (Level 1).

The Overseas Banking Group is required to disclose additional detailed information on its risk management practices and capital adequacy on a

quarterly basis. This information is made available to users via the Overseas Banking Group’s website (www.westpac.com.au).

-Westpac New Zealand Treasury also maintains a contingent

funding plan that outlines the steps that should be taken by

Westpac New Zealand in the event of an emerging 'funding

crisis' The plan is aligned with Westpac New Zealand's

broader Liquidity Crisis Management Policy which is

approved by Westpac New Zealand BRCC.

-The NZ Branch funding and liquidity risk is measured and

managed in accordance with the policies and processes

defined in the Group BRiskC approved Liquidity Risk

Management Framework, which is part of the NZ Banking

Group’s Board-approved Risk Management Strategy.

-Responsibility for managing the NZ Branch liquidity and

funding positions in accordance with the Liquidity Risk

Management Framework is delegated to Group Treasury,

under the oversight of the Overseas Banking Group's ALCO

and Treasury Risk. Group BRiskC oversees the Overseas

Banking Group's ALCO with regards to the APRA APS 210

obligations.

-The Overseas Banking Group monitors the composition and

stability of its funding to allow it to remain within its funding

risk appetite. This includes compliance with both the

liquidity coverage ratio and net stable funding ratio.

Market risk

-The Market Risk Management Framework describes the

Overseas Banking Group’s approach to managing traded

and non-traded market risk and is approved by the Group

BRiskC. Westpac New Zealand operates its own Market Risk

Management Framework that is closely aligned with that of

the Overseas Banking Group. The Westpac New Zealand

Framework is approved by the Westpac New Zealand BRCC.

-Traded market risk includes interest rate, foreign exchange,

commodity, credit spread and volatility risks. Non-traded

market risk includes interest rate and foreign exchange

risks.

-The NZ Banking Group’s framework does not allow for

equity risk to be held.

-Market risk is managed using VaR limits, NaR and structural

risk limits (including credit spread and interest rate basis

point value limits) as well as scenario analysis and stress

testing.

-The Group BRiskC approves the risk appetite for traded and

non-traded risks through the use of VaR, NaR and specific

structural risk limits.

-The Overseas Banking Group’s RISKCO has approved

separate VaR sub-limits for the trading activities of the

Overseas Banking Group’s Financial Markets and Treasury

units.

-Market risk limits are assigned to business management

based upon the Overseas Banking Group’s risk appetite and

business strategies in addition to the consideration of

market liquidity and concentration of risks.

-Market risk positions are managed by the trading and

Treasury desks consistent with their delegated authorities

and the nature and scale of the market risks involved.

-Daily monitoring of current exposure and limit utilisation is

conducted independently by the Financial Markets and

Treasury Risk unit, which monitors market risk exposures

against VaR and structural risk limits. Oversight of risk

specific to the NZ Banking Group is performed by the

Financial Markets and Treasury Risk unit. Daily VaR position

reports are produced by risk type, by product lines and by

geographic region. Quarterly reports are produced for the

Overseas Banking Group’s MARCO, Overseas Banking

Group’s RISKCO and Group BRiskC.

-Daily stress testing and backtesting of VaR results are

performed to support model integrity and to analyse

extreme or unexpected movements. A review of the

potential profit and loss outcomes is also undertaken to

monitor any skew created by the historical data.

-The Group BRiskC has approved a framework for profit or

loss escalation which considers both single day and 20 day

cumulative results.

-Treasury’s ALM unit is responsible for managing the non-

traded interest rate risk including risk mitigation through

hedging using derivatives. This is overseen by the Financial

Markets and Treasury Risk unit and reviewed by the

Overseas Banking Group's MARCO, Overseas Banking

Group’s RISKCO and Group BRiskC.

Notes to the financial statements

Note 31 Risk management, funding and liquidity risk and market risk (continued)
Climate change risk

The NZ Banking Group recognises climate change as a major threat to our collective wellbeing and is committed to transparency and action

across its business to address climate change. While this is not a material financial risk as at 30 September 2025 (30 September 2024: not a

material financial risk), climate change risk is evolving and is expected to have a more significant impact on the NZ Banking Group’s material

financial risks in the future.

The two main sources of financial risks arising from climate change are physical risks and transition risks. Physical risks emanating from climate

change can be event-driven (acute) such as increased severity and frequency of extreme weather events (e.g., cyclones, droughts, floods, and

fires). They can also relate to longer-term shifts (chronic) in precipitation and temperature and increased variability in weather patterns or other

long-term changes such as sea level rise. Transition risks are risks associated with the transition to a lower-carbon global economy, the most

common of which relate to policy and legal actions, technology changes, market responses, and reputational considerations.

The NZ Banking Group seeks to understand the potential for climate-related transition and physical risks to impact its business, including their

possible impact on credit risk, regulatory and reporting obligations, and our reputation.

The NZ Banking Group has considered the impact of climate-related risks on its financial position and performance and while the effects of climate

change represent a source of uncertainty, the NZ Banking Group has concluded that climate-related risks do not have a material impact on the

judgements, assumptions and estimates for the year ended 30 September 2025 (30 September 2024: no material impact). Refer to Note 13.1 for

further information on how climate change risk is considered as part of credit risk.

31.2 Funding and liquidity risk

The NZ Banking Group aims to maintain a mix of retail and wholesale funding, with emphasis on the value of core funding consistent with the

principles inherent in BS13.

31.2.1 Liquidity modelling

Westpac New Zealand is subject to the conditions of BS13. The following metrics are calculated and reported on a daily basis by Westpac New

Zealand in accordance with BS13:

●the level of liquid assets held;

●the one-week mismatch ratio;

●the one-month mismatch ratio; and

●the one-year core funding ratio.

In addition, the Overseas Banking Group calculates the following liquidity ratios for Westpac New Zealand in accordance with the Overseas Bank’s

liquidity risk framework under APRA Prudential Standard APS 210 Liquidity:

●liquidity coverage ratio; and

●net stable funding ratio.

31.2.2 Sources of funding

Sources of funding are regularly reviewed to maintain a wide diversification by currency, geography, product and term. Sources include, but are

not limited to:

●deposits;

●debt issues;

●loan capital;

●proceeds from sale of marketable securities;

●repurchase agreements with central banks;

●related entities;

●principal repayments on loans;

●interest income; and

●fees and commissions income.

Term Lending Facility and Funding for Lending Programme

From 26 May 2020 until the extended date of 28 July 2021, the Reserve Bank made available a Term Lending Facility (‘TLF’), to offer loans for a

maximum term of five years at the rate of the Official Cash Rate, with access to the funds linked to banks’ lending under the TLF Scheme. As at 30

September 2025, Westpac New Zealand has a balance of $24 million under the TLF (30 September 2024: $42 million).

On 11 November 2020, the Reserve Bank announced that additional stimulus would be provided through a Funding for Lending Programme (‘FLP’),

commencing in December 2020. The FLP provides funding to banks at the prevailing OCR for a term of three years, secured by high quality

collateral. The size of funding available under the FLP includes an initial allocation of 4% of each bank’s eligible loans (as defined by the Reserve

Bank). A conditional additional allocation of up to 2% of eligible loans is also available, subject to growth in eligible loans, for a total size of up to

6% of eligible loans. The FLP ran from 7 December 2020 to 6 June 2022 for the initial allocations and ended on 6 December 2022 for the additional

allocations. The FLP term sheet is available on the Reserve Bank’s website. As at 30 September 2025, Westpac New Zealand has a balance of $1,110

million under the FLP (30 September 2024: $2,981 million).

Liquid assets

The following table shows the NZ Banking Group’s qualifying liquid assets held for the purpose of managing liquidity risk. These assets are eligible

for repurchase agreements with the Reserve Bank and are held in cash, government, local government and highly rated investment grade

securities. The level of liquid asset holdings is reviewed frequently and is consistent with regulatory, balance sheet and market condition

requirements.

As at 30 September 2025, the NZ Banking Group has undertaken repurchase agreements with the Reserve Bank, under the FLP and TLF, using RMBS. For the FLP,

the repurchase cash amount as at 30 September 2025 is $1,110 million (30 September 2024: $2,981 million), which is recorded within other financial liabilities on the

balance sheet, with underlying securities to the value of $1,503 million provided under the arrangement (30 September 2024: $3,989 million). For the TLF, the

repurchase cash amount at 30 September 2025 is $24 million (30 September 2024: $42 million), which is recorded within other financial liabilities on the balance

sheet, with underlying securities to the value of $29 million provided under the arrangement (30 September 2024: $50 million).

31.2.4 Contractual maturity of financial liabilities

The following table presents cash flows associated with financial liabilities, payable at the balance sheet date, by remaining contractual maturity.

The amounts disclosed in the table are the future contractual undiscounted cash flows, whereas the NZ Banking Group manages inherent liquidity

risk based on expected cash flows.

Cash flows associated with these financial liabilities include both principal payments as well as fixed or variable interest payments incorporated

into the relevant coupon period. Principal payments reflect the earliest contractual maturity date. Derivative financial instruments designated in

hedge accounting relationships and used as economic hedges are expected to be held for their remaining contractual lives, and reflect gross cash

flows over the remaining contractual term.

Trading derivatives that are considered economic hedges are included as ‘held for hedging purposes’ in the following table. Derivatives held for

trading, which excludes economic hedges, and certain liabilities classified in “Other financial liabilities” which are measured at FVIS are not

managed for liquidity purposes on the basis of their contractual maturity, and accordingly these liabilities are presented in the up to 1 month

column. Only the liabilities that the NZ Banking Group manages based on their contractual maturity are presented on a contractual undiscounted

basis in the following table.

31.3 Market risk

31.3.1 VaR

The NZ Banking Group uses VaR as one of the mechanisms for controlling both traded and non-traded market risk.

VaR is a statistical estimate of the potential loss in earnings over a specified period of time and to a given level of confidence based on historical

market movements. The confidence level indicates the probability that the loss will not exceed the VaR estimate on any given day.

VaR seeks to take account of all material market variables that may cause a change in the value of the portfolio, including interest rates, FX rates,

price changes, volatility and the correlations between these variables. Daily monitoring of current exposures and VaR and structural limit

utilisation is conducted independently by the Financial Markets and Treasury Risk unit. These limits are supplemented by escalation triggers for

material profit or loss, and stress testing of risks beyond the 99% confidence interval.

The key parameters of VaR are:

Holding period1 day

Confidence level99%

Period of historical data used1 year

31.3.2 Traded market risk

The NZ Banking Group’s exposure to traded market risk arises out of its FM and Treasury trading activities. The FM trading book activity represents

dealings that encompass book running and distribution activity. The types of market risk arising from FM trading activity include interest rate risk,

foreign exchange risk, credit spread risk and volatility risk.

Treasury’s trading activity represents dealings that include the management of interest rate, foreign exchange and credit spread risks associated

with the wholesale funding task, liquid asset portfolios and foreign exchange repatriations.

The table below depicts the aggregate VaR, by risk type, for the year ended 30 September:

Non-traded market risk includes IRRBB – the risk to interest income from a mismatch between the duration of assets and liabilities that arises in

the normal course of business activities.

NII sensitivity is monitored in terms of the NaR. A simulation model is used to calculate the NZ Banking Group’s potential NaR. This combines the

underlying balance sheet data with assumptions about runoffs and new business, expected repricing behaviour and changes in wholesale market

interest rates.

IRRBB VaR includes interest rate risk and other basis risks used for internal management purposes.

Risk mitigation

IRRBB stems from the ordinary course of banking activities, including structural interest rate risk (the mismatch between the duration of assets

and liabilities) and capital management.

The NZ Banking Group hedges its exposure to such interest rate risk using derivatives. Further details on the NZ Banking Group’s use of hedge

accounting are discussed in Note 23.

The same controls as used to monitor traded market risk allow management to continuously monitor and manage IRRBB.

Foreign currency exposures

Notes to the financial statements

Westpac Banking Corporation - New Zealand Banking Group77

This section contains the additional disclosures required by the Order.
i. General information (Unaudited)

Overseas Bank

The Overseas Bank's principal office and address for service of process is Level 18, Westpac Place, 275 Kent Street, Sydney, New South Wales

2000, Australia.

Limits on material financial support by the Overseas Bank

APRA requires that the ELE of the Overseas Bank limit its non-equity exposures to New Zealand banking subsidiaries to 5% of the Overseas Bank’s

Level 1 Tier 1 capital, as part of an initiative to reduce Australian bank non-equity exposure to their respective New Zealand banking subsidiaries.

The ELE consists of the Overseas Bank and its subsidiary entities that have been approved by APRA to be included in the ELE for the purposes of

measuring capital adequacy. New Zealand banking subsidiaries include Westpac New Zealand and any of its subsidiaries.

Exposures for the purposes of this limit include all committed, non-intraday, non-equity exposures including derivatives and off-balance sheet

exposures. For the purposes of assessing this exposure, the 5% limit excludes equity investments and holdings of capital instruments in New

Zealand banking subsidiaries.

While the limit and associated conditions do not apply to the ELE’s non-equity exposures to the NZ Branch (which is within the ELE), the limit and

associated conditions do apply to the NZ Branch’s non-equity exposures to New Zealand banking subsidiaries. As at 30 September 2025, the ELE’s

non-equity exposures to New Zealand banking subsidiaries affected by the limit were below 5% of Level 1 Tier 1 capital of the Overseas Bank.

APRA has also confirmed the terms on which the Overseas Bank ‘may provide contingent funding support to a New Zealand banking subsidiary

during times of financial stress’. APRA has confirmed that, at this time, only covered bonds meet its criteria for contingent funding arrangements.

Ranking of local creditors in liquidation

There are material legislative restrictions in Australia (being the Overseas Bank’s country of incorporation) which subordinate the claims of certain

classes of unsecured creditors of the NZ Branch on the assets of the Overseas Bank (including a claim made or proved in an insolvent winding-up

or liquidation of the Overseas Bank) to those of other classes of unsecured creditors of the Overseas Bank.

The legislation described below is relevant to limitations on possible claims made by unsecured creditors of the NZ Branch (together with all other

senior unsecured creditors of the Overseas Bank) and New Zealand depositors on the assets of the Overseas Bank (including a claim made or

proved in an insolvent winding-up or liquidation of the Overseas Bank) relative to those of certain other classes of unsecured creditors of the

Overseas Bank.

Section 13A(3) of the Banking Act 1959 (Commonwealth of Australia) (‘Australian Banking Act’) provides that if an ADI becomes unable to meet

its obligations or suspends payment, the assets of the ADI in Australia are to be available to satisfy the liabilities of the ADI in the following order:

•first, certain obligations of the ADI to APRA (if any) arising under Division 2AA of Part II of the Australian Banking Act in respect of amounts

payable by APRA to holders of ‘protected accounts’ (as defined in the Australian Banking Act) as part of the FCS for the Australian

Government guarantee of ‘protected accounts’ (including most deposits) up to A$250,000 per account holder in the winding-up of the ADI;

•second, APRA’s costs (if any) in exercising its powers and performing its functions relating to the ADI in connection with the FCS;

•third, the ADI’s liabilities (if any) in Australia in relation to ‘protected accounts’ that account-holders keep with the ADI. ‘Protected accounts’

do not include accounts kept at a foreign branch of an ADI;

•fourth, the ADI’s debts (if any) to the Reserve Bank of Australia;

•fifth, the ADI’s liabilities (if any) under an emergency financial ‘industry support contract’ that is certified by APRA in accordance with the

Australian Banking Act; and

•sixth, the ADI’s other liabilities (if any) in the order of their priority apart from the above.

Section 13A(3) of the Australian Banking Act affects all unsecured liabilities of the NZ Branch, which, as at 30 September 2025, amounted to

$15,909 million (30 September 2024: $13,292 million).

Section 13A(4) of the Australian Banking Act also provides that it is an offence for an ADI not to hold assets (other than goodwill and any assets or

other amount excluded by the prudential standards) in Australia of a value that is equal to or greater than the total amount of its deposit liabilities

in Australia, unless APRA has authorised the ADI to hold assets of a lesser value. During the year ended 30 September 2025, the Overseas Bank has

at all times held assets (other than goodwill) in Australia of not less than the value of the Overseas Bank’s total deposit liabilities in Australia.

Under section 16 of the Australian Banking Act, on the winding-up of an ADI, APRA’s cost of being in control of an ADI’s business, or having an

administrator in control of an ADI’s business, is a debt due to APRA. Debts due to APRA shall have, subject to section 13A(3) of the Australian

Banking Act, priority over all other unsecured debts of that ADI.

The requirements of the above provisions have the potential to impact on the management of the liquidity of the New Zealand business of the

Overseas Bank.

Pending proceedings or arbitration

Except as listed below there are no pending legal proceedings or arbitration concerning any member of the Overseas Banking Group or the NZ

Banking Group that may have a material adverse effect on the Overseas Bank or the NZ Banking Group.

The Overseas Bank is defending a class action proceeding which was commenced in December 2019 in the Federal Court of Australia on behalf of

certain investors who acquired an interest in the Overseas Bank's securities between 30 June 2014 and 19 November 2019. The proceeding

involves allegations relating to market disclosure issues connected to the Overseas Bank’s monitoring of financial crime over the relevant period

and matters which were the subject of the AUSTRAC civil proceedings. The damages sought on behalf of members of the class have not yet been

specified. However, in the course of a procedural hearing in August 2022, the applicant indicated that a preliminary estimate of the losses that

may be alleged in respect of a subset of potential group members exceeded AUD$1 billion. While it remains unclear how the applicant will

ultimately formulate their estimate of alleged damages claimed on behalf of group members, it is possible that the claim may be higher (or lower)

than the amount referred to above. Given the time period and the nature of the claims alleged to be in question, along with the reduction in the

Overseas Bank's market capitalisation at the time of the commencement of the AUSTRAC civil proceedings, it is likely that any total alleged

damages (when, and if, ultimately articulated by the applicant) will be significant. The Overseas Bank continues to deny both that its disclosure

was inappropriate and, as such, that any group member has incurred damage. The Court has made orders for a hearing to commence on 5 April

2027 with an estimated duration of six weeks.

The Overseas Bank includes details of other legal proceedings in its financial statements.

S&PAA-Stable

On 6 March 2024, Moody's Investors Services upgraded the Overseas Bank's credit rating to Aa2. The ratings action resulted from the application

of Moody's Investors Service's Advance Loss Given Failure analysis. On 26 May 2024, Fitch upgraded the Overseas Bank's credit rating to AA-

reflecting the build-up of buffers by the bank through existing capital instruments to meet APRA's loss-absorbing capacity requirements. The

Overseas Bank's credit rating assigned by S&P has remained unchanged during the two years immediately preceding the signing date.

Other material matters

Reserve Bank review of overseas bank branches

On 21 August 2024, the Reserve Bank released the proposed Branch Standard under the Deposit Takers Act 2023. The proposed Branch Standard

will require that overseas bank branches only conduct business with wholesale clients; the total size of an overseas bank's branch cannot exceed

NZ$15 billion in total assets; and dual-operating branches (such as the NZ Branch) only conduct business with “large corporate and institutional

clients" (LCIC).

Policy decisions released by the Reserve Bank on 17 July 2025 propose that LCIC means those with consolidated annual turnover of over NZ$50

million, total assets of over NZ$75 million or total assets under management of over NZ$250 million (for funds management entities only). The

implementation date is expected to be 1 December 2028.

The NZ Branch currently provides financial markets, trade finance and international payment products and services to customers referred by

Westpac New Zealand. We expect the Reserve Bank's Branch Standard will require changes to the activities the NZ Branch undertakes and as a

result, Westpac New Zealand may also make changes to the scope of the activities it undertakes.

Depositor Compensation Scheme

The Depositor Compensation Scheme (DCS) took effect from 1 July 2025. If a licensed deposit taker (including Westpac New Zealand) fails, the

DCS will protect eligible depositors with money held in DCS-protected accounts up to NZ$100,000 per depositor, per deposit taker. Most

transaction, savings, notice, term deposit and PIE accounts held with Westpac New Zealand are protected accounts. The NZ Branch does not offer

deposits covered by the DCS. The DCS is administered by the Reserve Bank. For more information about the scheme, please refer to the Reserve

Bank's website.

i. General information (Unaudited) (continued)
Reserve Bank review of capital settings for deposit takers

On 31 March 2025, the Reserve Bank announced a review of the key capital settings for deposit takers. On 25 August 2025, it released a

consultation paper. For Group 1 deposit takers (including Westpac New Zealand) the key proposals include:

●Removal of AT1 instruments from the capital stack.

●Two options for capital ratio requirements:

oOption 1: A total Common Equity Tier 1 (CET1) capital ratio requirement of 14%, with a total capital ratio requirement of 17% (including

a prudential capital buffer (PCB) ratio of 8%).

oOption 2: A total CET1 capital ratio requirement of 12%, with a total capital ratio requirement of 15% (including a PCB ratio of 6%) and

an additional Loss Absorbing Capacity (LAC) requirement of 6%. Tier 2 capital and LAC instruments would be required to be issued

internally (for example to the Overseas Bank) and LAC would take a form similar to Tier 2 capital.

●More granular standardised risk weights, including lower risk weights in some areas.

●Setting the long-run level for the counter-cyclical capital buffer component of the PCB at 1%.

The Reserve Bank is expected to make its final decisions in December 2025, with the implementation timeline to be announced in the first quarter

of the 2026 calendar year. The outcome of the review remains uncertain.

APRA announcement to phase out AT1 as eligible bank capital

On 8 July 2025, APRA released a consultation paper on implementing the phase out of AT1 instruments. This included changes to APRA's

prudential and reporting frameworks resulting from the removal of AT1 instruments. Under the revisions, large internationally active banks such as

the Overseas Bank will replace 1.5% of AT1 with 1.25% of Tier 2 capital and 0.25% of CET1 capital. The total CET1 requirement, including regulatory

buffers, will increase from 10.25% to 10.50%. There is no overall increase in total capital requirements for banks.

APRA has also proposed changes to the leverage ratio, which will see the leverage ratio calculation based on CET1 capital rather than Tier 1 capital.

Should the changes be implemented as proposed, this will result in a reduction in the reported leverage ratio. The minimum leverage ratio of 3.5%

is proposed to remain unchanged.

APRA intends to finalise changes to the relevant prudential standards in 2025, with the updated framework coming into effect from 1 January 2027.

In addition, from this date, existing AT1 instruments would be eligible to be included as Tier 2 capital, until their first scheduled call date. Existing

Overseas Bank AT1 instruments would reach their first scheduled optional redemption dates by 2031 at the latest.

ii. Additional financial disclosures (continued)
Additional information on interest rate sensitivity

Sensitivity to interest rates arises from mismatches in the interest rate characteristics of assets and the corresponding liability funding. One of the

major causes of these mismatches is timing differences in the repricing of assets and liabilities. These mismatches are actively managed as part of

the overall interest rate risk management process, which is conducted in accordance with the NZ Banking Group’s policy guidelines.

The following table presents a breakdown of the earlier of the contractual repricing or maturity dates of the NZ Banking Group’s net asset position

as at 30 September 2025. The NZ Banking Group uses this contractual repricing information as a base, which is then altered to take account of

customer behaviour, to manage its interest rate risk.

Additional mortgage information

Residential mortgages by LVR as at 30 September 2025

LVRs are calculated as the current exposure divided by the NZ Banking Group’s valuation of the associated residential property at origination.

The NZ Banking Group utilises data from its loan system to obtain origination valuations. For loans originated prior to 1 January 2008, or those

originated outside of the loan system, the origination valuation is not recorded in the system and is therefore, due to system limitations, not

available for disclosure. For these loans, the NZ Banking Group utilises the earliest valuation recorded as the closest available alternative to

estimate an origination valuation.

Exposures for which no LVR is available have been included in the ‘Exceeds 90%’ category in accordance with the requirements of the Order.

Market risk

The NZ Banking Group’s aggregate market risk exposure is derived in accordance with BPR140 Market risk exposure and is calculated on a six-

monthly basis. The end-of-period aggregate market risk exposure is calculated from the period end balance sheet information.

For each category of market risk, the NZ Banking Group’s peak end-of-day aggregate capital charge is derived in accordance with the scalar

approach as referred to in BPR140 Market risk exposure. Under this approach, the end-of-period capital charge is scaled by the ratio of peak

capital charge to end-of-period capital charge using the internal VaR method.

The following table provides a summary of the NZ Banking Group’s notional capital charges by risk type as at the reporting date and the peak end-

The Overseas Bank does not conduct any insurance or non-financial activities in New Zealand outside of the NZ Banking Group.

The NZ Banking Group’s involvement in securitisation, funds management, other fiduciary activities, and marketing and

distribution of insurance products

Securitisation

The NZ Banking Group uses structured entities to securitise its financial assets through the Covered Bond Programme and Westpac New Zealand’s

internal residential mortgage-backed securitisation programme. Refer to Note 28 Securitisation, covered bonds and other transferred assets for

further information and amounts of outstanding securitised assets.

Funds management and other fiduciary activities

The NZ Banking Group conducts investment and other fiduciary activities that result in the holding or placing of assets on behalf of individuals,

trusts, retirement benefit plans and other institutions. These assets are not the property of the NZ Banking Group and accordingly are not included

in these financial statements, with the exception of the PIE Funds which are treated as controlled entities of Westpac New Zealand (refer to Note

22 for further details). Where controlled entities incur certain liabilities in respect of these activities, a right of indemnity exists against the assets

of the applicable trusts. As these assets are sufficient to cover liabilities, and it is not probable that the controlled entities will be required to settle

them, the liabilities are not included in the financial statements.

The PIE Funds are managed by a member of the NZ Banking Group (refer to Note 22 for further details) and invest in deposits with Westpac New

Zealand. Westpac New Zealand is considered to control the PIE Funds, and as such they are consolidated within the financial statements of the NZ

Banking Group.

Information about risk

Risk Management Framework

Proactive risk management and risk culture are fundamental to the NZ Banking Group. They underpin our strength and resilience, shape the way

we operate and provide clear parameters for decision-making. Strengthening risk management remains a priority as the nature of the risks we

face may change and evolve.

The Overseas Bank's Board Risk Appetite Statement documents the Overseas Bank’s risk appetite settings for each of the 11 Risk Classes. The Risk

Appetite Statement is reviewed and approved annually by the Board and is monitored and reported quarterly through the RISKCO and Group

BRiskC. Reporting includes the details of activity for any risk appetite measures outside tolerance.

The NZ Banking Group manages risks through the Risk Management Framework which is centred around customers, a strong risk culture and the

Three Lines of Defence model. The Three lines of Defence model consists of the following principles:

The First Line of Defence owns and manages the risks they originate

Business units are responsible for proactively identifying, evaluating, owning, monitoring, managing and controlling the existing and emerging

risks in their businesses. They manage business activities within approved risk appetite and policies. In managing its risk, the First Line of Defence

establishes and maintains appropriate governance structures, controls, resources and self-assessment processes, including issue identification,

recording and escalation procedures.

The Second Line of Defence provides independent insight, oversight and challenge of First Line activities

The Second Line of Defence is an independent function that develops risk management frameworks, defines guardrails, provides objective review

and challenge regarding the effectiveness of risk management within the First Line business and executes specific risk management activities

where functional independence and/or specific risk capability is required. Its approach is risk-based and proportionate to First Line activities.

The Third Line of Defence provides independent objective assurance

The Third Line of Defence is an assurance function that provides the Board, Board Committees and senior management with independent and

objective evaluation of the adequacy and effectiveness of the NZ Banking Group’s governance, risk management and internal controls.

Risk Management Frameworks

The Overseas Bank and Westpac New Zealand together had systems in place to monitor and control adequately the material risks of the following

relevant members of the NZ Banking Group:

●BTNZ;

●BTFGNZL;

●WFSGNZL;

●WGINZL;

●WHNZL;

●WCNZL; and

●WNZGL.

The Overseas Bank and the NZ Branch together had systems in place to monitor and control adequately the material risks of the NZ Branch. The

remaining relevant members of the NZ Banking Group are not considered to have material risks.

The NZ Branch has a NZ Branch Risk Committee, NZ Branch RISKCO, which meets quarterly and oversees the management of material risk classes

that include, but are not limited to, funding and liquidity risk, market risk, credit risk, operational risk, compliance and conduct risk, financial

crime, cyber risk, reputation and sustainability risk, strategic risk, risk culture, and across the NZ Branch.

BTNZ maintains a Risk Management Framework approved by its Board which is closely aligned to the Overseas Banking Group and Westpac New

Zealand’s Risk Management Framework whilst reflecting BTNZ’s specific regulatory and operating environment.

Westpac New Zealand, a member of the NZ Banking Group, is a locally incorporated registered bank. Westpac New Zealand’s Risk Management

Framework is closely aligned with that of the Overseas Banking Group, and the Board of Westpac New Zealand is responsible for the risk

management of that bank and its subsidiaries.

The Boards of the other entities making up the NZ Banking Group have ultimate responsibility for overseeing the effective deployment of the Risk

Management Frameworks for these entities.

Other key material risks

Capital adequacy risk

Capital adequacy risk is the risk that the Overseas Banking Group has an inadequate level or composition of capital to support its normal business

activities and to meet its regulatory capital requirements under both normal or stressed operating environments. Refer to Note 30 Capital

management for further details.

Operational risk

Operational risk is the risk of loss resulting from inadequate or failed internal processes, people and systems, or from external events. The NZ

Banking Group identifies operational risks as part of managing its business, considering emerging risks in response to changes in business,

business strategy and in the external environment. The NZ Banking Group manages this type of risk through robust processes and controls

including effective and timely remediation of material operational issues and incidents.

The NZ Banking Group applies the Overseas Bank’s Operational Risk Management Framework which outlines the business requirements for

managing operational risk. This covers governance, risk and control assessments, incident management, issues management, and ongoing

reporting and monitoring. Westpac New Zealand has its own Operational Risk Management Framework that is closely aligned with that of the

Overseas Bank and is approved by the Westpac New Zealand BRCC.

Compliance and conduct risk

Compliance and conduct risk is the risk of failing to abide by the NZ Banking Group’s compliance obligations or otherwise failing to have

behaviours and practices that deliver suitable, fair and clear outcomes for customers and that support market integrity.

The NZ Banking Group identifies compliance and conduct risks as part of managing the business which includes considering emerging risks and

responding to changes in the business, business strategy and external environment. The NZ Banking Group manages compliance and conduct

risks by implementing and embedding frameworks, systems, policies, standards, procedures and controls.

The NZ Branch applies the Overseas Bank’s Compliance and Conduct Risk Management Framework which is supported by compliance and

conduct policies to assist the business in managing its compliance and conduct risks. The Framework is approved by the Overseas Bank’s Board

Risk Committee. The NZ Banking Group, excluding the NZ Branch, operates its own Compliance and Conduct Risk Management Framework that is

closely aligned with that of the Overseas Bank and is approved by the Westpac New Zealand BRCC.

Financial crime risk

Financial crime risk is the risk that the NZ Banking Group fails to prevent financial crime and/or fails to comply with applicable global financial

crime regulatory obligations. Financial crime risk includes bribery and corruption, money laundering, sanctions and export control violations, tax

evasion, fraud and scams, terrorist financing and proliferation.

The NZ Banking Group helps prevent financial crime by proactively identifying, assessing, mitigating and reporting financial crime risks and by

complying with all applicable global and local financial crime regulatory obligations. This means that our financial crime risks must be managed

through robust controls and systems and that we must promptly own, investigate and remediate financial crime incidents where they do occur.

Westpac New Zealand has its own Financial Crime Risk Management Framework that is closely aligned with that of the Overseas Bank and is

approved by the Westpac New Zealand BRCC.

Cyber risk

Cyber risk is the risk that the NZ Banking Group’s or its third parties’ data or technology are inappropriately accessed, manipulated or damaged

from cybersecurity threats or vulnerabilities.

The NZ Banking Group proactively manages cyber risk exposure, to limit the likelihood of inappropriate access, manipulation or damage to the NZ

Banking Group’s and its third parties’ data and technology. This includes embedding cyber security capabilities such as data security controls,

application protection controls, and identity and access management.

Reputational & sustainability risk

Reputational & sustainability risk is the risk of failing to recognise or address ESG issues and the risk that an action, inaction, transaction,

investment, or event will reduce trust in the NZ Banking Group’s integrity and competence by clients, counterparties, investors, regulators,

employees or the public.

The NZ Banking Group seeks to cultivate stakeholders’ trust in the NZ Banking Group’s integrity and competence and to balance commerciality of

decisions with stakeholder expectations, potential impacts on people, communities or the environment, recognising that ESG issues can involve

complex, interconnected and at times competing considerations.

Strategic risk

Strategic risk is the risk that the NZ Banking Group makes inappropriate strategic choices, does not implement its strategies successfully, or does

not respond effectively to changes in the operating environment.

The NZ Banking Group manages strategic risk through annual strategic reviews and financial target setting, ongoing monitoring of performance

and changes and, stress testing and/or scenario analysis.

Registered bank disclosures

Westpac Banking Corporation - New Zealand Banking Group93

vi. Risk management policies (continued)
Risk culture

There is a risk that the NZ Banking Group’s culture does not promote and reinforce behavioural expectations and structures to identify,

understand, discuss and act on risks.

The NZ Banking Group promotes a risk culture which supports its purpose, strategy and values and the ability to manage risk effectively. The NZ

Banking Group regularly assesses its risk culture and undertakes initiatives to continually improve.

Reviews of the NZ Banking Group’s risk management systems

Westpac New Zealand Audit and the Overseas Banking Group’s Group Audit function periodically review the NZ Banking Group’s Operational,

Compliance and Conduct, Market, Funding and Liquidity, Credit and Model Risk Frameworks. The periodic reviews follow an internal audit

methodology which aims at achieving a review of the very high-risk areas annually, high-risk areas bi-annually, medium risk areas every three

years and low risk areas every four years.

The reviews discussed above in this section are not conducted by a party which is external to the NZ Banking Group or the Overseas Banking

Group, though they are independent and have no direct authority over the activities of management.

Various external reviews of the NZ Banking Group’s risk management system have been conducted during the year ended 30 September 2025 as

part of ongoing compliance with regulatory requirements.

Internal audit function of the NZ Banking Group

The NZ Banking Group internal audit services are provided by Westpac New Zealand’s and the Overseas Banking Group’s internal audit functions.

Westpac New Zealand’s internal audit function (‘WNZL Audit’) oversees all entities within the NZ Banking Group with the exception of the NZ

Branch whose internal audit services are overseen by the Overseas Banking Group’s internal audit function. WNZL Audit is headed by the Chief

Internal Auditor who reports directly to the Westpac New Zealand Board Audit Committee, while the Overseas Banking Group’s internal audit

function is headed by the General Manager Group Audit who reports to the Overseas Banking Group’s Board Audit Committee.

Both internal audit functions provide independent assurance on the effectiveness of governance, risk management and internal controls across

the NZ Banking Group’s operations. The level of risk across all material risk classes determines the scope and frequency of individual audits.

The Westpac New Zealand Board Audit Committee meets regularly, and its responsibilities include the oversight of NZ Banking Group’s statutory

financial reporting requirements and the internal audit function, with the exception of the NZ Branch. The Overseas Banking Group Board Audit

Committee also meets regularly and has similar responsibilities for the NZ Branch.

Access to the Overseas Bank disclosures

The Overseas Banking Group is required to disclose additional detailed information on its risk management practices and capital adequacy on a

quarterly basis. This information is made available to users via the Overseas Banking Group’s website (www.westpac.com.au).

Independent Auditor’s
Report

To the New Zealand business of Westpac Banking Corporation (the Branch)

Report on the audit of the aggregated disclosure statement

Information and Credit and Market Risk Exposures and Capital Adequacy) (the financial statements and

supplementary information) which comprise:

—the aggregated financial statements comprised of:

—the balance sheet as at 30 September 2025;

—the income statement and statements of comprehensive income, changes in equity and cash flows for

the year then ended; and

—notes, including material accounting policy information and other explanatory information (excluding

the information disclosed in accordance with Schedules 2, 4, 7, 9, 11 and 13 of the Registered Bank

Disclosure Statements (Overseas Incorporated Registered Banks) Order 2014 (as amended) (Order)

and is included within notes 12, 13, 30 and 31 and registered bank disclosures i to vi);

(the financial statements).

—the supplementary information that is required to be disclosed in accordance with Schedules 4, 7, 11 and

13 of the Order (the supplementary information), contained within notes 12, 13, 30 and 31 and

registered bank disclosures ii, iii, v and vi.

We have not audited the information related to General Information and Credit and Market Risk Exposures

and Capital Adequacy disclosed in accordance with Schedules 2 and 9 of the Order within note 30 and

registered bank disclosures i and iv, and our opinion does not extend to this information.

In our opinion, the accompanying financial statements of the New Zealand business of Westpac Banking

Corporation and its financial reporting group, as defined by the Order, (the NZ Banking Group) within pages 6

to 77:

—give a true and fair view of the NZ Banking Group’s financial position as at 30 September 2025 and its

financial performance and cash flows for the year ended on that date; and

—comply with New Zealand Generally Accepted Accounting Practice, which in this instance means New

Zealand Equivalents to International Financial Reporting Standards (NZ IFRS) issued by the New

Zealand Accounting Standards Board and the International Financial Reporting Standards issued by

the International Accounting Standards Board.

In our opinion, the accompanying supplementary information of the NZ Banking Group:

—presents fairly the matters to which it relates;

—is disclosed in accordance with those schedules; and

—has been prepared, in all material respects, in accordance with any conditions of registration relating to

the disclosure requirements, imposed under section 74(4)(c) of the Banking (Prudential Supervision)

Act 1989.

Basis for opinion

We conducted our audit in accordance with International Standards on Auditing (New Zealand) (ISAs (NZ)). We

believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our opinion.

We are independent of the NZ Banking Group in accordance with Professional and Ethical Standard 1

International Code of Ethics for Assurance Practitioners (Including International Independence Standards) (New

Zealand) issued by the New Zealand Auditing and Assurance Standards Board and the International Ethics

© 2025 KPMG, a New Zealand Partnership and a member firm of the KPMG global organization of independent member firms affiliated with KPMG International Limited, a

98Westpac Banking Corporation - New Zealand Banking Group

Standards Board for Accountants’ International Code of Ethics for Professional Accountants (including
International Independence Standards) (IESBA Code), as applicable to audits of financial statements of public

interest entities. We have also fulfilled our other ethical responsibilities in accordance with Professional and

Ethical Standards 1 and the IESBA Code.

Our responsibilities under ISAs (NZ) are further described in the Auditor’s responsibilities for the audit of the

financial statements and supplementary information section of our report.

Our firm has provided other services to the NZ Banking Group in relation to regulatory compliance assurance,

climate report limited assurance and agreed upon procedures. Subject to certain restrictions, partners and

employees of our firm may also deal with the NZ Banking Group on normal terms within the ordinary course of

trading activities of the business of the NZ Banking Group. These matters have not impaired our independence as

auditor of the NZ Banking Group. The firm has no other relationship with, or interest in, the NZ Banking Group.

Scoping

The scope of our audit is designed to ensure that we perform adequate work to be able to give an opinion on the

financial statements and supplementary information as a whole, taking into account the structure of the NZ

Banking Group, the financial reporting systems, processes and controls, and the industry in which it operates.

The context of our audit is set by the NZ Banking Group’s major activities in the financial year ended 30

September 2025. The NZ Banking Group has certain operational processes which are critical to financial reporting

for the NZ Banking Group that are undertaken outside of New Zealand. We worked with a KPMG network firm

engaged in the Westpac Banking Corporation group audit to understand and examine certain processes, test

controls and perform other substantive audit procedures that supported material balances, classes of transactions

and disclosures within the NZ Banking Group’s financial statements and supplementary information. This enabled

us to evaluate the effectiveness of the controls over those processes and consider the implications for the

remainder of our audit work.

Materiality

The scope of our audit was influenced by our application of materiality. Materiality helped us to determine the

nature, timing and extent of our audit procedures and to evaluate the effect of misstatements, both individually

and on the financial statements and supplementary information as a whole. The materiality for the financial

statements and supplementary information as a whole was set at $86.9 million determined with reference to a

benchmark of the NZ Banking Group’s profit before tax. We chose the benchmark because, in our view, this is a

key measure of the NZ Banking Group’s performance.

Key audit matters

Key audit matters are those matters that, in our professional judgement, were of most significance in our audit of

the financial statements in the current period. We summarise below those matters and our key audit procedures to

address those matters in order that the Branch may better understand the process by which we arrived at our

audit opinion.

Our procedures were undertaken in the context of and solely for the purpose of our audit opinion on the financial

statements as a whole and we do not express discrete opinions on separate elements of the financial statements.

Provision for expected credit losses

The key audit matter

NZ IFRS 9 Financial Instruments (NZ IFRS 9) requires the recognition of expected credit losses (ECL). As

disclosed in Note 12 of the financial statements, the provision for ECL on loans was $450 million for the NZ

Banking Group at 30 September 2025. The NZ Banking Group uses models that estimate ECL using three main

components: probability of default (PD), loss given default (LGD) and exposure at default (EAD). The NZ Banking

Group applies forward-looking economic scenarios and associated probability weights to their models when

determining an ECL estimate.

We identified the assessment of provision for ECL as a key audit matter. A high degree of audit effort, including

specialised skills and knowledge, was required because of the significant measurement uncertainty as follows:

—Model estimations: Complex and subjective auditor judgement was applied in assessing the NZ

Banking Group’s modelled estimations of ECL due to the inherently judgmental and complex nature of

Westpac Banking Corporation - New Zealand Banking Group99

the models, namely those used to derive the PD, LGD and EAD, and key associated model
assumptions. Certain models and model assumptions are the key drivers of complexity and

uncertainty, and minor changes to the model assumptions could have a significant effect on the NZ

Banking Group’s calculation of the provision for ECL.

—Economic judgements: Complex and subjective auditor judgement was applied in assessing the NZ

Banking Group’s economic judgements, including the severity of the forward-looking downside

economic scenario and the probability weightings used in the models.

How the matter was addressed in our audit

The following are the primary procedures we performed to address this key audit matter.

—We evaluated the design and tested the operating effectiveness of certain internal controls related to

the ECL estimation process. This included certain controls relating to:

omodel validation and monitoring;

ocredit reviews that determine customer risk grades (CRGs) which is a key assumption used in

the models for a population of corporate customers; and

othe selection of the downside economic scenario and probability weightings.

Additionally, we evaluated IT general controls over key IT applications used by the NZ Banking Group

in measuring ECL, and relevant IT application controls including those related to the transformation of

critical data elements and the flow of these from various systems into the models.

—We involved our credit risk professionals with specialised skills and knowledge who assisted in

evaluating the NZ Banking Group’s models and associated model assumptions as follows:

oevaluating the NZ Banking Group’s methodology used in the models to derive the PD, LGD and

EAD and associated model assumptions against criteria in the accounting standards and

industry practice;

oinspecting model code for the calculation of certain model components to assess its

consistency with the NZ Banking Group’s modelling methodology;

oreperforming the model output for a selection of models using the NZ Banking Group’s

documented methodology and comparing our output with the NZ Banking Group’s outputs; and

oreperforming model monitoring for a selection of the current models to evaluate the models’

performance.

—For a selection of corporate customers, we challenged the NZ Banking Group’s assessment of CRGs

using relevant information in the loan file including the customer’s financial position to inform our

overall assessment of the CRG against the NZ Banking Group’s policies.

—We involved our economic and credit risk professionals with specialised skills and knowledge, who

assisted in challenging the macroeconomic variable forecasts against external economic data,

evaluating the severity of the downside economic scenario and evaluating the probability weights.

—We assessed the appropriateness of the NZ Banking Group’s disclosures in the financial statements

using our understanding obtained from our testing and against the requirements of NZ IFRS 9.

IT Systems and Controls

The key audit matter

The NZ Banking Group’s operations and financial reporting are highly dependent on the effective operation of IT

general controls in complex and interdependent IT systems to process and record a high volume of transactions.

The controls include those relating to user access management, change management and IT operations, as well

as automated business process controls.

We identified the IT systems and controls over financial reporting as a key audit matter as there is a risk that gaps

in the IT general controls may undermine the integrity in recording financial information and the preparation of the

financial statements. Our audit approach could significantly differ depending on the effective operations of the NZ

Banking Group’s IT general and automated controls and reliability of system generated reports.

We involved IT specialists in assessing this key audit matter.

100Westpac Banking Corporation - New Zealand Banking Group

How the matter was addressed in our audit
We tested the control environment for key IT applications used in processing significant transactions and

recording balances in the general ledger. We also tested automated controls embedded within these systems

which support the effective operation of technology-enabled business processes. Our IT specialists were used

throughout the engagement as a core part of our audit team.

Our procedures included:

—User Access Management: We tested the processes by which users are granted, reviewed, and removed

from access to critical IT applications and infrastructure, including the management of privileged roles, to

assess whether access was appropriately restricted to authorised personnel.

—Change Management: We assessed the procedures governing changes to IT systems. We also evaluated

the appropriateness of users with change access to ensure segregation of duties was maintained.

—IT Operations: We tested controls over system job scheduling, issue resolution, and monitoring of system

integrity.

—Automated Business Process Controls: We reviewed system-enforced controls such as automated

reconciliations, segregation of duties, configuration-based calculations, and data integrity mechanisms to

assess their effectiveness in supporting accurate financial reporting.

Where control deficiencies were identified related to IT general controls or automated controls, we tested

compensating controls or performed additional procedures.

Other information

The Directors, on behalf of the NZ Banking Group, are responsible for the other information. The other information

comprises information included in the annual report and disclosure statement presented in accordance with

Schedule 2 of the Order on pages 3 to 5, 78 to 85 (excluding the information on page 85 relating to registered

bank disclosure ii which forms part of the supplementary information) and 95 to 97, and the information relating to

credit and market risk exposures and capital adequacy requirements disclosed in accordance with Schedule 9 of

the Order within registered bank disclosure iv, but does not include the financial statements and supplementary

information and our auditor’s report thereon. The other information also includes the Westpac New Zealand

Climate Report (Climate Report) to be published at a later date. Other than the Climate Report which we will

receive at a later date, we have received all the other information expected to be included in the annual report and

disclosure statement.

Our opinion on the financial statements and supplementary information does not cover any other information and

we do not express any form of assurance conclusion thereon.

In connection with our audit of the financial statements and supplementary information our responsibility is to read

the other information and in doing so, consider whether the other information is materially inconsistent with the

financial statements and supplementary information or our knowledge obtained in the audit, or otherwise appears

materially misstated.

If, based on the work we have performed on the other information that we obtained prior to the date of the

auditor’s report, we conclude there is a material misstatement of this other information, we are required to report

that fact. We have nothing to report in this regard.

When we read the Climate Report, if we conclude that there is a material misstatement therein, we are required to

communicate the matter to directors.

Other matter

The financial statements and supplementary information of the NZ Banking Group, for the year ended 30

September 2024 was audited by another auditor who expressed an unmodified opinion on the financial

statements and supplementary information on 7 November 2024.

Use of this independent auditor's report

This independent auditor’s report is made solely for the Branch. Our audit work has been undertaken so that we

might state to the Branch those matters we are required to state to them in the independent auditor’s report and

for no other purpose.

To the fullest extent permitted by law, none of KPMG, any entities directly or indirectly controlled by KPMG, or any
of their respective members or employees, accept or assume any responsibility and deny all liability to anyone

other than the Branch for our audit work, this independent auditor’s report, or any of the opinions we have formed.

Responsibilities of Directors for the aggregated disclosure statement

The Directors, on behalf of the NZ Banking Group, are responsible for:

—the preparation and fair presentation of the financial statements in accordance with Clause 25 of the Order;

—the preparation and fair presentation of supplementary information in accordance with Schedules 2, 4, 7, 9,

11 and 13 of the Order;

—implementing the necessary internal control to enable the preparation of an aggregated set of financial

statements that is free from material misstatement, whether due to fraud or error; and

—assessing the ability of the NZ Banking Group to continue as a going concern. This includes disclosing,

as applicable, matters related to going concern and using the going concern basis of accounting unless

they either intend to liquidate or to cease operations or have no realistic alternative but to do so.

Auditor’s responsibilities for the audit of the financial statements and supplementary information

Our objective is:

—to obtain reasonable assurance about whether the financial statements and supplementary information as

a whole are free from material misstatement, whether due to fraud or error; and

with ISAs NZ will always detect a material misstatement when it exists.

Misstatements can arise from fraud or error. They are considered material if, individually or in the aggregate, they

could reasonably be expected to influence the economic decisions of users taken on the basis of the financial

statements and supplementary information.

Assurance Report

To the New Zealand business of Westpac Banking Corporation (the Branch)

Report on the supplementary information relating to Credit and Market Risk Exposures and Capital

Adequacy Requirements

Conclusion

Our limited assurance conclusion has been formed on the basis of the matters outlined in this report.

Based on our limited assurance engagement, which is not a reasonable assurance engagement or audit,

nothing has come to our attention that would lead us to believe that the supplementary information relating to

Credit and Market Risk Exposures and Capital Adequacy Requirements, disclosed in registered bank disclosure

iv within the aggregated disclosure statement, is not, in all material respects disclosed in accordance with

Schedule 9 of the Registered Bank Disclosure Statements (Overseas Incorporated Registered Banks) Order

2014 (as amended) (the Order).

Information subject to assurance

We have reviewed the supplementary information relating to Credit and Market Risk Exposures and Capital

Adequacy Requirements, as disclosed in registered bank disclosure iv within the aggregated disclosure statement

for the period ended 30 September 2025.

Criteria

The supplementary information relating to Credit and Market Risk Exposures and Capital Adequacy Requirements

comprises the information that is required to be disclosed in accordance with Schedule 9 of the Order.

Standards we followed

We conducted our limited assurance engagement in accordance with Standard on Assurance Engagements 3100

(Revised) Compliance Engagements (SAE 3100 (Revised)) issued by the New Zealand Auditing and Assurance

Standards Board (Standard). We believe that the evidence we have obtained is sufficient and appropriate to provide

a basis for our limited conclusion. In accordance with the Standard, we have:

—used our professional judgement to plan and perform the engagement to obtain limited assurance that the

supplementary information relating to Credit and Market Risk Exposures and Capital Adequacy

Requirements, are free from material misstatement and non-compliance, whether due to fraud or error;

—considered relevant internal controls when designing our assurance procedures, however we do not

express a conclusion on the effectiveness of these controls;

—ensured that the engagement team possesses the appropriate knowledge, skills and professional

competencies;

—obtained an understanding of the process, models, data and internal controls implemented over the

preparation of the information relating to Credit and Market Risk Exposures and Capital Adequacy

Requirements;

—performed inquiry and analytical procedures over the Credit and Market Risk Exposures and Capital

Adequacy Requirements;

—obtained an understanding of the Branch’s compliance framework and internal control environment over the

information relating to Credit and Market Risk Exposures and Capital Adequacy Requirements,

© 2025 KPMG, a New Zealand Partnership and a member firm of the KPMG global organization of independent member firms affiliated with KPMG International Limited, a

Westpac Banking Corporation - New Zealand Banking Group103

including the Branch’s assessment of any matters of non-compliance with the Reserve Bank of New
Zealand’s Prudential Requirements; and

—agreed the information relating to Credit and Market Risk Exposures and Capital Adequacy Requirements,

extracted from the Branch’s models, accounting records or other supporting documentation to the

aggregated disclosure statement

How to interpret limited assurance and material misstatement and non-compliance

In a limited assurance engagement, the assurance practitioner performs procedures, primarily consisting of

discussion and enquiries of management and others within the entity, as appropriate, and observation and

walk-throughs, and evaluates the evidence obtained. The procedures selected depend on our judgment,

including identifying areas where there is a risk of material misstatement and non-compliance with Schedule 9

of the Order.

The procedures performed in a limited assurance engagement vary in nature and timing from and are less in

extent than for a reasonable assurance engagement. Consequently, the level of assurance obtained in a

limited assurance engagement is substantially lower than the assurance that would have been obtained had a

reasonable assurance engagement been performed.

Misstatements, including omissions, within the supplementary information relating to Credit and Market Risk

and Capital Adequacy Requirements and non-compliance are considered material if, individually or in

aggregate, they could reasonably be expected to influence the relevant decisions of the intended users taken

on the basis of the supplementary information relating to Credit and Market Risk and Capital Adequacy

Requirements.

Inherent limitations

Because of the inherent limitations of an assurance engagement, together with the internal control structure it is

possible that fraud, error or non-compliance with compliance requirements may occur and not be detected.

A limited assurance engagement for the period ended 30 September 2025 does not provide assurance on whether

compliance with Schedule 9 of the Order will continue in the future.

Use of this assurance Report

This report is made solely for the Branch. Our assurance work has been undertaken so that we might state to

the Branch those matters we are required to state to them in the assurance report and for no other purpose.

Our report should not be regarded as suitable to be used or relied on by anyone other than the Branch for any

purpose or in any context. Any other person who obtains access to our report or a copy thereof and chooses to

rely on our report (or any part thereof) will do so at its own risk.

To the fullest extent permitted by law, none of KPMG, any entities directly or indirectly controlled by KPMG, or

any of their respective members or employees accept or assume any responsibility and deny all liability to

anyone other than the Branch for our work, for this independent assurance report, and/or for the opinions or

conclusions we have reached.

Our conclusion is not modified in respect of this matter.

Directors' responsibility for the supplementary information relating to Credit and

Market Risk Exposures and Capital Adequacy Requirements

The Directors of the Branch are responsible for the disclosure of the supplementary information relating to

Credit and Market Risk Exposures and Capital Adequacy Requirements in accordance with Schedule 9 of the

Order, which the Directors have determined meets the needs of the Branch. This responsibility includes such

internal control as the Directors determine is necessary to enable compliance and to monitor ongoing

compliance and to enable the disclosure of the supplementary information relating to Credit and Market Risk

Exposures and Capital Adequacy Requirements that is free from material misstatement and non-compliance

whether due to fraud or error.

Our responsibility

Our responsibility is to express a conclusion to the Branch on whether anything has come to our attention that

would lead us to believe that, in all material respects the supplementary information relating to Credit and

Market Risk Exposures and Capital Adequacy Requirements has not been disclosed in accordance with

Schedule 9 of the Order for the period ended 30 September 2025.
