New Zealand has a well-established banking sector that supports households, businesses, farmers and international companies. Banks provide essential financial services, including current accounts, savings accounts, mortgages, personal loans, business financing, credit cards and international money transfers.
The country’s banking industry includes major Australian-owned banks, locally owned financial institutions and international banks that operate through branches or New Zealand subsidiaries. While the largest institutions dominate lending and everyday banking, smaller banks provide alternatives for customers seeking specialised products, community-focused services or different approaches to managing their money.
The Reserve Bank of New Zealand (RBNZ) regulates the registration and prudential supervision of banks. According to the Reserve Bank’s published information, New Zealand has 26 registered banks as of September 2026. Four large Australian-owned banking groups—ANZ, ASB, BNZ and Westpac—account for most lending in the country.
This guide explains the major banks in New Zealand, introduces locally owned institutions, identifies international banking providers and outlines the regulatory framework that protects the stability of the financial system.

The Central Bank: Reserve Bank of New Zealand
The Reserve Bank of New Zealand, also known by its Māori name, Te Pūtea Matua, is the country’s central bank. It has responsibilities that differ from those of commercial banks such as ANZ, ASB and Westpac.
The RBNZ works to promote monetary and financial stability. Its responsibilities include monetary policy, prudential supervision of banks, oversight of certain financial institutions and maintaining confidence in the financial system.
The central bank also contributes to the stability of New Zealand’s payment and settlement systems.
Unlike commercial banks, the RBNZ does not primarily serve the public through ordinary current accounts, personal loans or residential mortgages. Individuals and businesses generally use commercial banks for these services.
The Reserve Bank also maintains the official register of banks authorised to operate in New Zealand. Consumers can use this register to check an institution’s legal name, registration status and published financial disclosures.
For anyone researching banks in New Zealand, the RBNZ register is the most appropriate starting point for distinguishing registered banks from other financial service providers.
The Big Four Banks in New Zealand
The Big Four are ANZ Bank New Zealand, ASB Bank, Bank of New Zealand and Westpac New Zealand. These institutions are subsidiaries or operations of major Australian banking groups and dominate New Zealand’s banking market.
1. ANZ Bank New Zealand
ANZ Bank New Zealand Limited is one of the country’s largest banking institutions. It offers personal banking, business accounts, savings products, home loans, credit cards and commercial financing.
The bank serves individuals, small businesses, agricultural enterprises and larger companies. Its services also include online and mobile banking, enabling customers to monitor transactions, make payments and manage accounts remotely.
ANZ’s connection to the wider Australia and New Zealand Banking Group provides access to an extensive regional banking network.
2. ASB Bank
ASB Bank Limited is another major banking provider in New Zealand. It offers everyday banking accounts, savings products, mortgages, personal loans, business banking and investment-related services.
ASB serves a broad customer base, including households, professionals and commercial organisations. Its digital services enable customers to manage accounts and carry out transactions without visiting a branch.
The bank is part of Commonwealth Bank of Australia’s wider banking group.
3. Bank of New Zealand (BNZ)
Bank of New Zealand, commonly known as BNZ, provides banking services to individuals and businesses throughout the country.
Its products include transaction accounts, savings accounts, mortgages, personal lending, credit cards and business finance. BNZ also provides services for commercial customers, including organisations that require more specialised financing arrangements.
The bank is owned by National Australia Bank, an Australian financial services group.
4. Westpac New Zealand
Westpac New Zealand Limited is a major provider of retail, business and commercial banking services.
Customers can access transaction accounts, savings products, home loans, personal lending and business financing. The bank also provides digital banking facilities for customers who prefer to manage their money online.
Westpac’s operations form part of the wider Westpac Banking Corporation group based in Australia.
Together, these four banks play a central role in New Zealand’s financial system. Their size, capital resources and extensive customer networks make them important providers of mortgages, business credit and everyday banking services.

Locally Owned Banks in New Zealand
Although the Big Four dominate the industry, New Zealand also has smaller banks with different ownership structures and areas of specialisation.
These institutions provide alternatives for customers who want to compare banking products, interest rates, fees and customer service.
1. Kiwibank
Kiwibank Limited is a New Zealand-owned bank established in 2001. It provides personal banking, savings accounts, mortgages, business banking and other financial services.
Its local ownership distinguishes it from the major Australian-owned banks. Kiwibank has developed a nationwide customer base through its branches and digital banking channels.
It is particularly relevant to customers who want to consider a locally owned alternative when comparing everyday banking and home loans.
2. TSB Bank
TSB Bank Limited is a New Zealand-owned bank with a long history of serving customers, particularly in the Taranaki region.
Its products include everyday accounts, savings accounts, mortgages, personal loans and business banking services.
TSB combines traditional banking services with digital account management. Its ownership structure and customer-focused approach distinguish it from the country’s larger Australian-owned institutions.
3. SBS Bank
SBS Bank originated as Southland Building Society and has a history of serving communities in the South Island.
It offers transaction accounts, savings products, mortgages, personal lending and other financial services.
SBS is included on the Reserve Bank’s registered bank list under its registered name, Southland Building Society. Its banking brand is SBS Bank.
4. The Co-operative Bank
The Co-operative Bank Limited operates using a cooperative ownership model. It provides personal accounts, savings products, mortgages and selected lending services.
Its structure differs from that of banks owned by conventional shareholder groups. Customers interested in cooperative banking may consider its products alongside those of larger institutions.
5. Heartland Bank
Heartland Bank Limited provides specialised financial products, including savings accounts, reverse mortgages and lending services.
The bank has developed expertise in areas such as vehicle finance and lending to particular customer groups.
Heartland’s product range differs from that of full-service retail banks, making it worth considering for customers seeking specific financial solutions.
Ownership note: These five institutions are commonly discussed as New Zealand-owned banking alternatives. However, ownership structures and the legal status of financial institutions can change, so current details should be checked before publication.

International and Foreign Banks Operating in New Zealand
New Zealand’s international banking sector connects the domestic economy with financial markets in Australia, Asia, Europe and North America.
Some overseas institutions establish locally incorporated subsidiaries, while others operate as branches of foreign banks. The legal structure affects how the institution is registered and supervised.

Other Names Frequently Associated with New Zealand Banking
Several names in older banking directories may appear alongside current registered institutions. Their status should be checked carefully before they are presented as separate banks.
National Bank of New Zealand: This was a major retail banking brand that became part of ANZ’s New Zealand operations. It should not be described as an independent registered bank today.
BankDirect: BankDirect has been associated with ANZ’s direct banking services. It should not automatically be counted as a separate registered bank.
HBS Bank: The name is associated with Heretaunga Building Society. A building society should not automatically be classified as a registered bank without checking the relevant official register.
Southland Building Society: This name appears on the Reserve Bank’s registered bank list and is associated with the SBS Bank brand.
Bank of China and Citibank: These names can refer to overseas banking groups or specific New Zealand registrations. The legal entity matters when determining whether an institution is a registered bank and which products it offers.
Making these distinctions improves the accuracy of bank directories and helps readers avoid confusing a trading name, a historical brand and a registered financial institution.

The Regulatory Environment in New Zealand
New Zealand’s banking sector operates under a regulatory framework designed to promote financial stability, support responsible banking and maintain public confidence.
Reserve Bank of New Zealand
The RBNZ is responsible for registering banks and supervising their financial soundness.
Registered banks must meet applicable prudential requirements and publish disclosure statements. These disclosures provide information about their financial condition, risk exposures and regulatory obligations.
The Reserve Bank also publishes information about bank credit ratings and material breaches of certain requirements.
Financial Markets Authority
The Financial Markets Authority (FMA) oversees financial markets and relevant conduct obligations under New Zealand law.
Its responsibilities include supervising aspects of financial market behaviour and enforcing applicable rules relating to financial products and services.
Financial Consumer Protection
New Zealand’s consumer protection framework includes requirements intended to improve transparency and the treatment of customers.
When comparing banks, consumers should review account conditions, interest rates, borrowing costs, complaint procedures and any restrictions that apply to financial products.
Depositor Compensation Scheme
New Zealand introduced a Depositor Compensation Scheme on 1 July 2025. The scheme protects eligible deposits up to NZ$100,000 per depositor, per licensed deposit taker, subject to the scheme’s rules.
Protection applies only to eligible deposits held with covered institutions. Not every investment or financial product qualifies, and customers should confirm whether their particular account is covered.
The scheme is an important consideration for savers comparing banks and other eligible deposit-taking institutions.
How to Choose a Bank in New Zealand
The most suitable bank depends on a customer’s financial needs, preferred services and circumstances.
Compare fees and account features. Review monthly charges, transaction fees, ATM access and any conditions attached to everyday accounts.
Check savings interest rates. Compare rates, withdrawal restrictions, minimum balances and promotional conditions before opening a savings account.
Review mortgage and loan products. Borrowers should consider interest rates, repayment terms, fees and lending eligibility.
Consider digital banking. Mobile applications and online banking can provide convenient access to accounts and payments. Customers who prefer face-to-face assistance may also want to check branch availability.
Check international services. People who regularly send or receive money overseas may benefit from comparing foreign exchange fees, transfer charges and international banking facilities.
Verify registration and deposit protection. Use the Reserve Bank’s register to confirm that the institution is registered and check the Depositor Compensation Scheme rules to determine whether eligible deposits are protected.

Conclusion
New Zealand’s banking sector combines large Australian-owned banking groups, locally owned institutions and international financial organisations.
ANZ, ASB, BNZ and Westpac dominate much of the domestic banking market. Kiwibank, TSB, SBS Bank, The Co-operative Bank and Heartland Bank offer alternatives for customers with different financial needs.
International institutions such as Bank of China, Citibank, HSBC, JPMorgan Chase, MUFG and Rabobank also contribute to the country’s financial system through their registered New Zealand operations.
Although the range of banking providers is broad, not every registered institution offers the same products or serves the same customers. Some focus on everyday banking, while others specialise in corporate finance, international transactions or agricultural lending.
Before opening an account, customers should compare fees, interest rates, account features and customer service. They should also confirm the institution’s legal status and check whether their deposits qualify for protection under New Zealand’s Depositor Compensation Scheme.
By understanding the different types of banks and how they operate, consumers and businesses can make more informed decisions about their banking needs.
