Opening a bank account in New Zealand is straightforward for most people — the identity verification process is the main step that catches people out. Here’s exactly what you need and how it works.
To open a bank account in NZ you need a valid photo ID (passport or NZ driver licence) plus proof of address. Most banks now offer online account opening — you can be set up within 1–3 business days. ANZ and ASB allow new arrivals to start the process before arriving in NZ.
What You Need to Open a Bank Account
New Zealand’s Anti-Money Laundering and Countering Financing of Terrorism Act (AML/CFT) 2009 requires all banks to verify your identity before opening an account.
For NZ Residents and Citizens
You need two pieces of documentation — one photo ID and one proof of address:
| Document type | Accepted examples |
|---|---|
| Photo ID (one required) | NZ driver licence, NZ passport, overseas passport |
| Proof of address (one required) | Utility bill, bank statement, IRD letter, rates notice — dated within 3 months |
You also need your IRD number for tax on interest earned. If you’re new to NZ and don’t have one yet, you can apply at ird.govt.nz — free and takes 5–10 business days. IRD offices can process same-day applications in person.
For Visa Holders and New Arrivals
| Document | Detail |
|---|---|
| Passport | Required — must be valid |
| NZ visa | Work, student, resident, or working holiday visa |
| Proof of NZ address | Employer offer letter, accommodation booking, halls of residence letter |
| IRD number | Apply at ird.govt.nz — bring passport and visa details |
Some banks are more flexible for new arrivals without a permanent NZ address. See best banks for new arrivals.
Online vs In-Branch Account Opening
Online Account Opening
Most major NZ banks now offer full online account opening — the fastest route for most people.
| Bank | Online opening | Estimated time |
|---|---|---|
| ANZ | Yes | 1–2 business days |
| ASB | Yes | Same day to 1 business day |
| BNZ | Yes | 1–2 business days |
| Westpac | Yes | 1–2 business days |
| Kiwibank | Yes | 1–3 business days |
How online verification works: Upload photos of your documents, then complete a live video ID check or use a verification service (such as RealMe). Some banks use automated biometric matching against your passport photo.
In-Branch Opening
Walk into any branch with your documents and open an account on the spot. Useful when:
- You’re having trouble with online ID verification
- You have non-standard documents
- You prefer face-to-face assistance
- You need to collect a banker’s card on the day
Special Situations
No Fixed Address Yet
If you’ve just arrived and don’t yet have a utility bill, most banks accept:
- Employer offer letter (on company letterhead, with your NZ address)
- Hotel or hostel booking confirmation
- University accommodation letter (for students)
- Letter from a sponsor or New Zealand host
Opening a Bank Account Before Arriving in NZ
ANZ and ASB both allow non-residents to start the account-opening process online before arriving. This is valuable for:
- People relocating for work who need an account ready for their first payslip
- International students who want banking sorted before they land
The account is typically finalised in-branch when you arrive with original documents.
International Students
Most banks open accounts for international students with:
- Passport and valid student visa
- Enrolment letter from your NZ institution
- Proof of NZ address (halls of residence confirmation is sufficient)
ASB and Kiwibank are well-regarded for international student account opening.
Children’s Accounts
For children under 18, a parent or guardian opens the account jointly. Required:
- Parent/guardian photo ID and proof of address
- Child’s birth certificate or passport
The Account Opening Process — Step by Step
- Choose your bank — compare NZ banks or read the ANZ vs ASB vs BNZ vs Westpac comparison
- Gather documents — photo ID + proof of address + IRD number
- Apply online or visit a branch
- Complete identity verification — biometric online check or in-person review
- Receive account details — typically by email within 1–3 business days
- Activate internet banking and mobile app
- Receive your debit card — arrives within 3–7 business days
IRD Number: When Do You Need It?
You don’t need an IRD number to open an account, but without one, banks are required to deduct Resident Withholding Tax (RWT) at the highest rate (45%) on any interest earned. Add it as soon as you have it.
Apply at ird.govt.nz — you’ll need passport and visa details. Processing takes 5–10 business days online.
Understanding NZ Account Numbers
NZ bank account numbers have a standard 15–16 digit format:
XX-XXXX-XXXXXXX-XX
- 2 digits — bank code (e.g., 01 = ANZ, 03 = Westpac, 06 = BNZ, 12 = ASB, 38 = Kiwibank)
- 4 digits — branch code
- 7 digits — account number
- 2–3 digits — account suffix (00 for everyday, 00–50 for savings)
You’ll give this number to your employer for payroll and to anyone who needs to pay you.
After Opening Your Account
- Set up internet banking and download the mobile app immediately
- Confirm your account number and double-check it before sharing with your employer
- Consider opening a savings account alongside your everyday account — see best savings accounts NZ
- If you need to send money internationally, set up Wise rather than using the bank’s wire transfer — see international transfers NZ
