How to switch banks in NZ

New Zealand has a shared, industry-run process for switching banks. You open the new account first, then your new bank gives you a single Switching Bank Request Form that authorises it to contact your old bank and move your automatic payments and direct debits across. The standard is 5 business days for your old bank to hand over the details once a valid request arrives. Run both accounts side by side for a pay cycle or two before closing the old one, and separately check anything not covered by the form — payroll, card-linked subscriptions, joint accounts.

This guide walks through the process end to end. It doesn't tell you which bank to switch to — that's a decision based on your own accounts, fees, and what you need from a bank. What it covers is how the move itself works, and what's easy to miss.

How does bank switching actually work in NZ?

New Zealand banks operate under a common switching standard coordinated by Payments NZ (the industry body that runs the country's payment systems). Rather than you contacting every company that takes a direct debit or automatic payment from your account, your new bank does that work using one authority form. The banks have agreed a timeframe — 5 business days for the old bank to supply the switching details — so the process doesn't stall indefinitely on one side.

What is the Switching Bank Request Form?

It's a single form your new bank gives you once you've opened an account with them. You fill in your old bank's name, your old account details, the date you want the switch to start, and your signature authorising the transfer. Your new bank then contacts your old bank on your behalf and arranges for your recurring payment instructions — direct debits, automatic payments, and any recurring bill payments — to be re-established against your new account number.

You complete one form. You don't need to individually contact every company that debits your account, though it's worth double-checking the ones that matter most (see below).

What happens to automatic payments and direct debits?

This is the part people worry about most, and it's the part the official process is built around. Once your Switching Bank Request Form is actioned:

• Automatic payments you've set up yourself (rent, savings transfers, loan repayments) get recreated against your new account.
• Direct debits that companies pull from your account (power, insurance, gym memberships) get their authority updated to your new account number.
• Your old payment instructions stay active at your old bank until the switch date, so nothing drops out mid-transfer.

What the form does not automatically move: anything charged directly to a debit or credit card rather than debited from an account. Streaming subscriptions, BNPL instalments on a linked card, and most app subscriptions fall in this category — those need updating individually with the provider, because there's no account-level authority to transfer.

2. Get the Switching Bank Request Form→
3. Old bank sends details (5 business days)→
4. Run both accounts in parallel→
5. Confirm everything's moved→
6. Close the old account

How long does switching banks take in NZ?

Expect the recurring-payment transfer itself to take about a week from a valid request, since the industry standard gives the old bank 5 business days to respond. But the sensible total timeline is longer than that: most guidance suggests running both accounts in parallel for at least one full pay cycle — ideally two — before closing the old one, so you can watch a full round of your usual bills and pay run through the new account and confirm nothing was missed.

What should I check before closing my old account?

A few things sit outside the standard switching form and are worth checking yourself:

• Your employer's payroll details. Update these directly with payroll or HR — the switching process doesn't touch where your pay lands.
• Any joint account arrangements, if the account you're moving is shared with a partner or flatmate.
• Card-linked subscriptions and BNPL instalments — anything charged to a card number rather than debited from the account itself.
• A buffer left in the old account for a week or two after the "official" switch date, in case a payment you didn't think of tries to come out.
• Whether the old account had an overdraft or linked credit facility — closing it may need a separate step with that bank.

Switching as a couple or household+

If you and a partner share bills, the practical approach is to move whichever account the shared automatic payments and direct debits actually sit on first, and treat any joint account as its own switch — both people typically need to sign the authority. If only one of you is switching your personal account, the shared bills usually aren't affected at all.

Switching banks while you have a mortgage+

A mortgage sitting with your old bank doesn't have to move for you to switch your everyday and savings accounts elsewhere — plenty of people bank day-to-day with one institution and hold lending with another. If you do want to move the mortgage itself, that's a separate, longer process involving your new bank's lending team and is worth treating as its own decision, not bundled into a same-week account switch.

Switching banks with BNPL instalments outstanding+

Buy-now-pay-later providers (Afterpay and similar) usually charge a linked debit or credit card directly rather than debiting your bank account, so they sit in the "update manually" category above. Check which card is linked in each BNPL app and update it once your new card has arrived, rather than assuming the bank switch covers it.

What can go wrong when switching banks?

The most common issue isn't the switch failing — it's closing the old account too early, before a quarterly or annual payment (an insurance renewal, a subscription that bills yearly) has had a chance to attempt against it. Keeping the old account open with a small buffer for a few weeks after the "main" switch is the simplest way to avoid this. The second most common issue is a card-linked payment that nobody thought to update, because it was never a direct debit in the first place.

Frequently Asked Questions

Is switching banks in NZ free?

The switching process itself — using the Switching Bank Request Form — doesn't carry an official fee under the Payments NZ standard. Any fees involved (account closure fees, early repayment charges on lending, card reissue costs) depend on your specific bank and accounts, so check with both banks directly before you start.

Do I have to close my old account to switch banks?

No. Many people keep an old account open, sometimes with a small balance, either as a backup or because some payments are easier to leave in place. Closing it is a choice, not a required step of the switching process.

Will switching banks affect my credit score?

Closing a bank account on its own is not typically reported in a way that affects your credit score. Credit score impacts usually come from credit facilities (loans, credit cards, overdrafts) rather than everyday transaction accounts — check the specifics of any lending attached to the account you're closing.

How do I make sure nothing gets missed when I switch?

Go through at least one full statement cycle on your old account before closing it, and match every line against your new account. Anything that shows up on the old statement but hasn't appeared on the new one is something to chase down individually.
