Our privacy policy

Wherever you provide personal information whether it’s online, in store, or over the phone, we’ll do everything we can to protect it from being used in the wrong way.

As a financial institution, we need to collect, hold, use and disclose your personal information as part of providing our products and services. We are bound by, and adhere to the privacy provisions as set out in the Privacy Act 1993.

Confidentiality of your information

If you’re a BNZ customer, we’ll only collect, hold, use, and disclose your personal information in accordance with our terms and conditions, and any applicable product terms and conditions, or if we’re required to by law. 

If you’re not a BNZ customer, we’ll collect, hold, use and disclose information about you for the purposes for which you provided it, or if we’re required to by law.

We won’t disclose any personal information to any third party for purposes unconnected with the purpose for which that information was provided to us, but we may share information collected in an anonymous aggregate form.

Your information is collected and held by BNZ, Private Bag 39806, Wellington Mail Centre, Wellington 5045. Under the Privacy Act, you’re entitled to see and request the correction of any personal information about you held by us. You can choose not to supply the information we request but it may affect our ability to accept you as a customer.


By providing us with your personal information online, whether via online form, live chat (BNZ Click to Chat), or by sending us an email, you agree to us:

i)  collecting, using, sharing and storing your personal information for the purposes you provided it; and
ii) retaining your personal information for contacting you via email, text message, online notification (without an unsubscribe facility) telephone, or post, in regards to your specific request, and for data analysis so that we can tailor and improve your online experience.
