The BNZ customer service number in New Zealand is 0800 275 269. You can also send BNZ a message in internet banking or visit a branch. Say that you want to make a complaint and have your name, a description of the problem, what you want BNZ to do to put it right and any relevant documents ready; BNZ gives each complaint a unique reference number, so note it down.

Interest or an account fee charged that you did not agree to? Raise it here as well, and we push it out to BNZ by email, social media and printed letters.

To dispute a transaction with BNZ, call BNZ, send a message in internet banking or visit a branch, and include as much supporting information as you can: the date, amount and merchant, receipts, order confirmations and your emails with the seller. BNZ says it can dispute most Visa network transactions on BNZ Visa and Flexi Debit Visa cards, for example goods that never arrived, goods not as described, a double charge or a charge after you cancelled, but not pending transactions. BNZ sets a time limit counted from the transaction date or the expected delivery date, so raise it promptly.

Dispute turned down and the charge left on your card? Open a case with us through our complaint process: our trained AI keeps coaching you on what to send BNZ next and when to push again.

To escalate a complaint with BNZ, ask for it to be passed to the BNZ Customer Resolution Team, which reviews complaints that could not be resolved earlier, and quote the unique reference number BNZ gave you. Put in writing what is still wrong and what you want BNZ to do, and attach statements, letters and screenshots. BNZ says it contacts you to discuss its final response and to explain its decision. The registered office of Bank of New Zealand is in Auckland; the full address is in the contact details at the top of this page.

Yes: Bank of New Zealand is a participant in the Banking Ombudsman Scheme, which is independent of participating banks, customers and government and looks into complaints about banks in New Zealand. The Banking Ombudsman Scheme generally expects BNZ to have had the chance to put things right first, so keep a record of every call, message, branch visit and the unique reference number.

Card dispute or loan decision to challenge? We help you write the complaint in minutes, drawing on thousands of complaint letters that actually worked.

Not if it asks you to reply or tap a link. BNZ says it never texts links to online banking or asks you to log in, and it has warned about texts claiming BNZ Rewards are about to expire. Calls from a so-called BNZ fraud team asking for a code are another trick.

Nothing has been reported about BNZ here yet. Our research shows what typically goes wrong at New Zealand's major banks: card transactions customers did not authorise or want to dispute, account fees and interest charges they did not expect, home loan and lending decisions, accounts restricted during security checks, and payments that arrive late or go to the wrong account.

Paid money to the wrong account and want it back? Be the first to report it, and your case becomes the record the next BNZ customer in the same spot can point to.

Your complaint gets its own public page on Complain.biz and we get to work: we bring it to the attention of BNZ through emails, social media, paper complaint letters and other tools at our disposal.

And we stay with it after you file. Our trained AI opens a case file for you and keeps coaching: what to reply, when to push again, and how to escalate if nothing happens.

Yes. We have an active community of consumers, and complaints here are public: people who ran into the same problem with BNZ can give you advice or back you up with their own story. A complaint with a community behind it is much harder to overlook.
