How Many Numbers Are in a New Zealand Bank Account Number? (NZ Format Explained)

How many digits are in a New Zealand bank account number?

A New Zealand bank account number usually has 15 or 16 digits, made up of four parts: a 2-digit bank code, a 4-digit branch code, a 7-digit account number, and a 2- or 3-digit suffix. Any hyphens or spaces you see are just for readability — the actual number is digits only.

If you’ve just moved to New Zealand and need to get your salary, rent, or benefit payments sorted, understanding bank account numbers is important. At Remitly, we know a single wrong digit can send a direct debit or transfer to the wrong account.

The basic format: 12-1234-1234567-00 (bank – branch – account – suffix).

In this guide, you’ll learn:

• How the four parts of your NZ account number fit together, with a worked example
• Why some accounts show 15 digits and others show 16
• How to enter your number correctly on payment forms, and where people usually get it wrong

If you haven’t opened an account yet, our guide to opening a bank account in New Zealand walks through the process step by step.

New Zealand bank account number format: bank, branch, account and suffix

Every standard NZ bank account number breaks down into four segments. Here’s what each one does:

Put together, a full account number looks like this: 12-1234-1234567-00, where the first two digits are the bank code, the next four are the branch code, the following seven are the account number, and the last two or three are the suffix. The hyphens are just there to make the number easier to read. Banks store and process account numbers as one continuous string of digits, so you can leave them out when you type your number into a form.

New Zealand’s banks all use this same four-part structure so that any bank can route a payment to any other bank correctly. This shared format sits behind Payments NZ‘s Bulk Electronic Clearing System, which lets an ANZ customer pay a Kiwibank account, or the other way round, without either bank needing special software to read the other’s numbers.

Why NZ bank account numbers can be 15 or 16 digits

The difference comes down to the suffix. Some banks use a two-digit suffix, which gives a 15-digit account number overall, while others use three digits, giving 16. Kiwibank, for example, uses a two-digit suffix, so if a form asks for three digits, you can add a leading zero — 01 becomes 001 — without changing the account it points to.

A few common slip-ups explain most digit-count mismatches:

• Leaving out the suffix altogether, since it’s easy to assume the seven-digit account number is the whole thing
• Dropping a leading zero when a bank code, branch code, or suffix starts with one
• Mixing up the account number and suffix fields on a form that splits them into separate boxes

How to find your account number and enter it correctly on payment forms

Most payment problems come down to where you look for your number, not the number itself. Here’s a simple way to get it right:

1. Open your banking app or internet banking and look for your full account number, usually shown under your account details.
2. Copy all four parts together — bank code, branch code, account number, and suffix — rather than just the seven-digit portion.
3. Keep any leading zeros. If your account number starts or ends in a zero, that zero is part of the number.
4. Match the digits to the form’s fields. Some forms want one long string; others split it into separate boxes for each segment.
5. If you can, send a small test payment before setting up a large or recurring one, so you can catch a mistake before it matters.

If a form only has a single box, enter all the digits together with no spaces or hyphens. If it splits the number into bank, branch, account, and suffix fields, put each segment in its matching box rather than guessing which box a stray digit belongs in.

This same account number is what you’ll give an employer for salary payments, a landlord for rent, a utility provider for a direct debit, or the IRD when setting up a refund — the format doesn’t change depending on who’s asking for it.

A rejected direct debit is often the result of a dropped suffix or a transposed digit. If a payment bounces, check your statement or banking app for the exact number rather than retyping from memory. Regular automatic payments, like rent or a phone bill, use the same as a one-off transfer.

Common NZ bank codes and how to verify yours

The first two digits of your account number are your bank code. Here are the codes for some of New Zealand’s major banks:

Branch codes route a payment to the right part of the banking network, but they don’t always match a physical branch you can visit. Kiwibank’s branch codes, for instance, run from 9000 to 9499, and its forms list every account as belonging to the Wellington branch regardless of where you actually bank, according to Kiwibank’s own account help page. It’s worth confirming your own bank and branch code rather than assuming from someone else’s, since two customers at the same bank can have different branch codes. Your banking app, a recent statement, or your bank’s official website will confirm it.

FAQs

How many digits does a New Zealand bank account number have?

Most New Zealand bank account numbers have 15 or 16 digits. They’re built from a 2-digit bank code, a 4-digit branch code, a 7-digit account number, and a 2- or 3-digit suffix. The total comes to 15 digits with a two-digit suffix, or 16 with a three-digit one.

How do I know which bank a number belongs to?

The first two digits of any New Zealand account number are the bank code, for example 01 for ANZ or 38 for Kiwibank. The next four digits are the branch code. If you’re not sure which bank a number belongs to, check it against your bank’s official code list or ask your bank directly.

What is the suffix on a NZ bank account number?

The suffix is the last two or three digits of your account number. It identifies which specific account you’re using if you hold more than one with the same bank, such as everyday, savings, or credit card accounts. It doesn’t change which bank or branch the account sits at.

Are NZ account numbers always 16 digits?

No. Some banks use a two-digit suffix, which makes a 15-digit account number, while others use three digits, making it 16. Both are correct; the difference is just how many digits that bank uses for its suffix, not an error in the number itself.

Do hyphens or spaces count as part of the account number?

No. Hyphens and spaces are only there to make the number easier to read on a screen or statement. The account number itself is digits only, so you can safely leave out any hyphens or spaces when typing it into a payment form.

What do I need to send money to a New Zealand account from overseas?

For an international transfer into a New Zealand account, you’ll typically need the recipient’s full name, address, complete account number, and the receiving bank’s SWIFT or BIC code. New Zealand doesn’t use the IBAN system, so you won’t need to provide or request one. Our guide to how an international money transfer works covers the process in more detail.

Will every New Zealand account number follow this exact format?

Almost every retail bank account in New Zealand follows the 15- or 16-digit, four-part format. A small number of newer digital-only providers show account details slightly differently, so if a number you’ve been given doesn’t match this pattern, it’s worth checking directly with whoever gave it to you. If you’re also dealing with an account across the Tasman, the digits work a little differently — see our guide on how many numbers are in an Australian bank account.

Key takeaways

• A standard NZ bank account number has 15 or 16 digits: 2 (bank) + 4 (branch) + 7 (account) + 2–3 (suffix).
• Hyphens and spaces are formatting only — the number itself is digits, with no letters or symbols.
• A two-digit suffix can be written as three digits by adding a leading zero, without changing the account.
• Branch codes route payments and don’t always match a physical branch — Kiwibank’s, for example, all show as Wellington.
• International transfers into NZ use SWIFT/BIC codes, a name, an address, and the full account number, not an IBAN.

Final check before you share your account number

Before you hand your account number to an employer, landlord, utility provider, or the IRD, it’s worth doing one last check: bank code, branch code, account number, and suffix, all matching what’s shown in your banking app or on a recent statement. Taking a moment to check the suffix and any leading zeros before setting up a direct debit can save you a bounced payment later.
