  2. Enter your access number from the back of your BNZ Eftpos, debit, or credit card.

  4. If we have your email address and mobile phone number on file, you’ll see them displayed. Confirm these are correct.
  5. Tap Set up now.
  6. You’ll receive a text message with a code. Enter it into the SMS code box.
  7. You’ll also receive a different code to your email address. Enter the code in the Email code box.
  8. Follow the prompt on your phone to set up additional secure login options, such as a five-digit PIN, Touch ID, Face ID, or Fingerprint login.

Troubleshoot common issues

Using multiple devices

You can set up the personal BNZ app on four devices at a time, and you can set up the Mobile Business Banking app on two devices.


Our mobile app protects your data using two different types of security: your login details, and your five-digital PIN or a biometric login (using your fingerprint or face).

  • Never give anyone your five-digit PIN or write it down.
  • Always log out of your app when you’re finished.
  • If possible, use mobile data instead of public Wi-Fi when doing your online banking.
  • We’ll never ask you to tell us (or anyone else) your password.
