The short answer
The five main banks in New Zealand are ANZ, ASB, BNZ, Westpac, and Kiwibank. Some of them let you begin your application from overseas, then activate the account after you arrive with your ID and proof of address. You should also apply for an IRD number soon after arriving — you need one for interest on your accounts to be taxed correctly.
Choosing a bank
ANZ, ASB, BNZ, Westpac, and Kiwibank are the main retail banks. All offer everyday transaction accounts with a debit card. Compare account fees and features on the banks' own official sites; fees change over time, so always check current information rather than relying on a figure quoted elsewhere.
Applying from overseas
Some banks let you start the application before you leave your home country. You complete the forms online, and the account is activated after you arrive, in person, with your ID and proof of your New Zealand address.
What you need to activate the account
A valid passport (and your visa details)
Proof of your New Zealand address (for example, a tenancy agreement or utility bill)
Get an IRD number
An IRD number is New Zealand's tax number, and you need one so that interest on your bank accounts is taxed correctly. As a new arrival, you can apply online using your passport details and your Immigration New Zealand application number — IRD verifies your identity with Immigration New Zealand, and the number usually arrives by text or email within about 2 days. Without an IRD number and a tax code, income (including wages) is taxed at the highest 'no-notification' rate. Applying from overseas is slower — it is a paper process and requires either a functioning NZ bank account or an IR997 due-diligence form.
Debit and credit cards
Your everyday account comes with a debit card for purchases and ATM withdrawals. All five banks offer credit cards, usually subject to income and credit checks after you arrive.
Frequently asked questions
Can I open a New Zealand bank account before I arrive?
You can start the application from overseas with some banks, but activation happens after you arrive, in person, with ID and proof of address.
Do I need an IRD number to open a bank account?
You can open the account first, but you need an IRD number for interest on your accounts to be taxed correctly.
How long does it take to get an IRD number?
New arrivals applying online usually receive it by text or email within about 2 days.
Which bank should I choose?
ANZ, ASB, BNZ, Westpac, and Kiwibank are the main options. Compare their current account fees and features on their official sites.
