The New Zealand bank account number format

A New Zealand bank account number is 16 digits long. The number is broken up into 4 distinct sections which highlight different features about the bank, branch and account details.

This is what the format of a NZ bank account number looks like without any dedicated account numbers inputted.

Below we’ll go through what each of the number sections indicate and why they are important.


What is a NZ bank number or prefix?


The first two numbers indicate the bank number or prefix. Each bank in New Zealand has their own allocated two digit number that identifies which bank a customer holds an account with.

12-1234-1234567-123


What is a NZ bank branch number?


The second block of numbers will indicate the bank branch number for where the account is located in NZ. Each bank can have several branch locations where customers can open an account. This number changes as per branch location.

12-1234-1234567-123



What is the account number?


The third block consists of a seven digit account number which will be unique to each customer and to your own bank account.

12-1234-1234567-123


What is the NZ bank account suffix?


The last block of numbers consists of three numbers that indicates the type of bank account held. If a customer has several accounts with the same bank, this suffix suffix number will change for each account held.

12-1234-1234567-123

Sometimes banks will have a 2 number suffix number. If this is the case, a zero may be used as the first number in the suffix sequence.
