Complaint procedure

Information you’ll need to supply

We’re committed to resolving your complaint quickly and fairly. To help us do this, please provide us with:

  • your name and address
  • a description of your concern
  • what you would like us to do to put things right
  • a phone number and the best time to contact you
  • any other relevant information.

What happens next

We will acknowledge your complaint within five business days and work to resolve it as quickly as possible. We’ll confirm that we’re looking into your complaint, and let you know when you can expect a response. We’ll also give you a unique reference number, so we can quickly find your record and keep you updated on our progress.

Taking a complaint further

If we’ve been unable to resolve your complaint and you’d like to pursue it further, you can ask for your complaint to be passed on to our Customer Resolution Team to review the matter independently on your behalf. You can also contact the team directly on 0800 788 999, or from overseas +64 9976 6345 (international toll charges may apply) from 9am-5pm, Monday to Friday. The team will assess your concerns and work with you to resolve your complaint.

We will always contact you to discuss our final response, and provide an explanation of what we’ve found, what we plan to do, and why we made the decision. This may be done over the phone, by secure email, or by letter. We’ll keep you updated on our progress with regular updates, but if you feel there’s extra information that will help us, you can contact us by phone. Please keep your unique reference number handy, as it will help us find your information quickly.

If you’re still not happy with our final response after we have fully investigated your complaint, you can seek help from the Banking Ombudsman Scheme. This is a free service that is independent of scheme participants, customers, and government. You can contact the Scheme on 0800 805 950 or +64 4915 0400 between 8.30am-5pm, Monday to Friday, or you can visit their website. If you’d like to read about recent cases, please refer to the ‘Guides & cases’ section of their website.

You can also report information about BNZ or any of our financial advisers, to the Financial Markets Authority using the contact details below:

Code of Banking Practice

We abide by the Code of Banking Practice pdf 349kb which sets out the principles of good banking practice.  The Code is set by the member banks of the New Zealand Banker’s Association, in consultation with the public, other industry participants, and the Banking Ombudsman. We agree to follow good banking practices as a minimum standard in our relationship with you.

Customer research panel

One of the ways we stay in touch with what your needs are is to regularly find out how you’re feeling about banking in general. We do this by asking you to take part in short online surveys and discussions to share your experiences.

To join you must:

  • be over 15-years old
  • not be employed in the banking industry
  • be a BNZ customer
  • live in New Zealand and have internet access.

You could even win supermarket vouchers for taking part.
