Questions people ask

Is 0800 735 901 really BNZ?

Yes. It's BNZ's 24/7 line for lost or stolen cards and suspected fraud, listed on BNZ's own contact page. But a caller showing this number may still be a scammer, because caller ID can be faked. Hang up and call it yourself.

I got a text from BNZ with a link to log in.

Don't tap it. In BNZ's words: "Avoid clicking links in emails or texts asking you to log in, which we'll never do." Open the BNZ app or type bnz.co.nz yourself.

A BNZ caller asked me to read out a code.

Hang up. BNZ will never ask you to share the authentication codes sent to you, even with a BNZ staff member. Call 0800 735 901 yourself.

A caller asked me to help catch a scammer at BNZ.

That's the scam. BNZ never asks you to transfer money to help catch a scammer or a bank employee. Hang up and call 0800 735 901.

I paid a scammer or shared my details. What now?

Call 0800 735 901 straight away. It's open 24 hours a day, every day. BNZ can block your cards and lock your online banking. Then go to What to do now.
