How to Open a NZ Bank Account and Get an IRD Number (2026)

Reader, before you start: this guide assumes you have a New Zealand visa (work, resident, or student) or are about to arrive on one, and you need to get your banking and tax setup working. For the wider move — visas, housing, healthcare — see moving to New Zealand in 2026.

What this guide covers

Two tasks decide whether your first weeks in New Zealand are smooth: opening a bank account and getting an IRD number (your tax number). They’re linked, the order matters, and most older guides describe a “chicken-and-egg” problem that recently got easier for people who simply wait until they’ve arrived. Here’s the current reality and the cleanest sequence.

• Why the order matters, and the rule that changed
• The IRD number: the two application paths and the 45% rate if you skip it
• Opening a bank account from overseas, and the deposit-but-can’t-withdraw catch
• Moving your money into New Zealand without losing a chunk to fees

The order matters — but less than it used to

The old advice went: you can’t get an IRD number without a working bank account, but you can’t do much without an IRD number. That loop still exists for one group — people applying from overseas before they arrive — but not for someone who waits until they’ve landed. The simplest path is to arrive first, then apply. More on both below.

The IRD number

An IRD number is your unique tax identification number. You need it to be taxed correctly on your pay, to open some accounts, and to join KiwiSaver (Inland Revenue — IRD numbers).

Skip it and you’re taxed at 45%

This is the reason to get one fast. Without an IRD number on file:

• Your employer must deduct PAYE at the “no-notification” rate of 45% — the top marginal rate — because you can’t complete a tax code declaration without the number.
• Interest paid to you is taxed at 45% too, the non-declaration withholding rate that’s applied since 1 April 2020 (Inland Revenue — RWT rates).

It’s not an extra penalty on top of normal tax — it’s being taxed as though you earn at the highest bracket. You reclaim overpayments later, but that’s a refund you wait a year for. Get the number first.

Two application paths

Which one applies to you depends on where you are when you apply.

Path 1 — “New arrival to New Zealand” (you’ve landed, or are arriving). This is the easy one. The current Inland Revenue page does not require a New Zealand bank account. What you need depends on your visa (Inland Revenue — new arrival IRD application):

• Australian passport holders: passport details.
• Resident visa holders: passport details plus your Immigration New Zealand application number.
• Work or student visa holders: the above plus your most recent overseas tax number, if you have one.

You get the number by text or email within 2 days of approval, or by post within 10 days.

Path 2 — “Living overseas” (you apply before moving). Here the bank-account rule still bites. You need a fully functional New Zealand bank account — or an IR997 customer due diligence form completed by a NZ bank — plus your passport, proof of address, overseas tax number, and your reason for applying (Inland Revenue — living overseas IRD application). Processing takes around 20 days.

What “fully functional” means

A “fully functional” account is one you can use for both deposits and withdrawals, with your identity verified — shown by a bank statement in your name with at least one deposit and one withdrawal, or a letter from the bank. An account you’ve opened but can’t yet withdraw from doesn’t qualify.

Opening a bank account

You can start from overseas. The major banks run migrant programs, and they differ in how soon you get full access.

Bank	Open from overseas	Deposit before arrival	Full access before in-person ID	Note
ANZ (Migrant Banking)	Up to 90 days before arriving	Yes	No — must verify ID at an ANZ branch in NZ	Requires a resident or work visa; working holiday visas not included
ASB	Yes, can fully activate remotely	Yes	Possible remotely via the ASB ID app (AU/UK/EU) or certified passport	Wants proof of overseas address within 12 months
BNZ	Yes, apply online	Account opens pending ID	Verify within 30 days at a branch or via an approved referee	—

The deposit-but-can’t-withdraw catch

With ANZ in particular, you can open the account and transfer your relocation money in before you arrive — but you can’t withdraw it until you turn up at a branch in New Zealand with your passport to verify your identity. ASB and BNZ offer remote verification routes that can unlock fuller access before you land. Don’t transfer your entire life savings into an account you can’t touch until you’ve confirmed how that bank’s verification works.

What banks ask for

• Your foreign passport.
• An eligible NZ visa (ANZ’s migrant package excludes working holiday visas).
• Proof of your overseas address — a recent bank statement or utility bill in your name.
• For some banks, passport certification by an approved referee if you’re outside Australia, the UK, or the EU.

The cleanest sequence

Putting it together, the path with the fewest snags:

1. While still overseas: open a migrant bank account remotely (ANZ up to 90 days out, or ASB/BNZ). Move your relocation funds in if you’re comfortable they’re safe there.
2. On arrival: go to a branch with your passport and verify your identity to fully activate the account.
3. Then apply for your IRD number via the “new arrival” path — passport plus your Immigration application number. No bank-account hoop on this route.
4. Get your number within ~2 days by email, give it to your employer and bank, and you’re taxed correctly from there.

If you must have the IRD number before you fly, use the offshore path — but then you genuinely need that fully functional account or an IR997 form first, which is the harder road.

Moving your money into New Zealand

Converting US dollars, pounds, or euros into NZD through a traditional bank wire usually costs you twice: a wire fee, and a margin baked into the exchange rate you don’t see.

Services like Wise convert at the mid-market rate — the real rate — and charge a separate, visible fee, typically 0.35% to 2% depending on the currency and route (Wise — how to use Wise in NZ). Wise also gives you NZD account details to receive New Zealand dollars; it states plainly that this “isn’t a bank account, but you can receive money in the same way” (Wise — NZD account). For a large one-off relocation transfer, the difference between the mid-market rate and a bank’s built-in margin can run into real money. Compare the all-in cost — fee plus exchange rate — not just the headline fee.

What they don’t tell you

• You probably don’t need a bank account for your IRD number. That’s the outdated advice. It’s true only if you apply from overseas. Arrive first, use the “new arrival” path, and the requirement disappears.
• Working holiday visas are shut out of some migrant accounts. ANZ’s migrant package needs a resident or work visa. On a working holiday, check which banks will open an account for you before you count on one.
• You can fund an account you can’t spend from. Money transferred into an unverified ANZ account is stuck until you verify ID in person. Know your bank’s rule before sending a large sum.
• 45% is the cost of waiting. Every payday without an IRD number on file is taxed at the top rate. You get it back eventually, but it’s an interest-free loan to the government in the meantime.
• The exchange rate is the hidden fee. A “no fee” bank transfer can cost more than a service charging a visible 1%, because the loss is hidden in a worse rate. Compare the amount that actually lands in NZD.

Frequently asked questions

Do I need a bank account before I can get an IRD number?

Only if you apply from overseas. If you apply after arriving in New Zealand using the “new arrival” path, you don’t — you just need your passport and your Immigration New Zealand application number. This is the simplest route and gets your number by email in about two days.

What happens if I don’t have an IRD number?

Your employer must tax your pay at the no-notification rate of 45%, and interest income is taxed at 45% too. That’s the top rate applied because you can’t file a tax code declaration without the number. You can reclaim overpaid tax later, but it’s far easier to get the number first.

Can I open a New Zealand bank account before I move?

Yes. ANZ, ASB, and BNZ all let you start from overseas — ANZ up to 90 days before arrival. You can usually deposit money in, but full access (withdrawals) often requires verifying your identity, either in person at a branch or, with some banks, remotely.

Why can’t I withdraw money from my new account?

Most banks require identity verification before they unlock withdrawals. With ANZ you do this in person at a NZ branch; ASB and BNZ offer remote verification. Until that’s done, you may be able to pay money in but not take it out — so don’t transfer everything before you’ve confirmed access.

What’s the cheapest way to move money to New Zealand?

Compare the all-in cost — transfer fee plus exchange rate. Services like Wise use the mid-market rate with a visible fee (typically 0.35–2%), which often beats a bank wire that hides a margin in the rate. For a large relocation sum, that gap matters.

How long does an IRD number take?

About two days by email if you apply as a new arrival in New Zealand, or up to 10 days by post. If you apply from overseas, allow around 20 days, plus extra time if you want it posted.

Next steps

If you can, keep it simple: open a migrant bank account before you fly, arrive, verify your ID at a branch, then apply for your IRD number as a new arrival — your number lands within days and your pay is taxed correctly from the start. Before you move a large relocation sum, compare the all-in cost of a transfer service against your bank. And if you’re coming from the US, read moving to New Zealand from the US too — your American tax filing obligations don’t stop when you open a Kiwi account.
