Steps to report fraud

If you notice anything that seems unusual, like: 


  • transactions in your accounts that you don’t recognise
  • your credit, debit, or EFTPOS card is lost or stolen
  • you’ve shared your banking credentials or verification codes with someone
  • you know or suspect that someone else has accessed your accounts without your authority.

1. Stop any communication

If you’re still on a call, hang up. If you’ve shared remote access, shut down or restart your device. 

Don’t give away any more information or access.

2. Secure your accounts

If you spot unauthorised transactions on your card, block your card and lock your online banking in the BNZ app immediately.

If you need help with this, contact us first.

3. Contact us

Contact us immediately on 0800 735 901 (+64 4 473 5901 from overseas).

Available 24 hours a day, 365 days of the year (including public holidays).

What BNZ will never do

If you get a message that looks like a scam, make sure you know what the companies you deal with, will or won’t ask you to do. For example, BNZ will never:

  • email or text you links to online banking and ask you to log in
  • send you a text message with a link to a website, or link to call us
  • ask you for information about your PIN number, bank account number, or password
  • ask you to verbally share the authentication codes sent to you by text or email, even with a BNZ staff member
  • ask you to transfer money to help catch a scammer or a bank employee who is scamming customers
  • send you a text message about account issues with a link to log in
  • ask you to download software to access your Internet Banking remotely
  • use international phone numbers to call or send you notifications.
