Name changes & Gender markers

This is a guide to legally changing your name and sex/gender markers in Aotearoa so that they can be reflected on official NZ documents and forms of I.D. such as passports, licenses, and more!

These guides are only eligible for persons born in Aotearoa, persons who hold/are entitled to citizenship, or persons who have permanent residency in Aotearoa.

Changing your name

There are two ways to doing this in Aotearoa:

  1. If you were NZ-born i.e. your birth was registered in Aotearoa, you can change your name on your birth certificate.

  2. If you were born outside of the country but hold citizenship or are entitled, under the Immigration Act 2009, to be in Aotearoa indefinitely (for example, as a permanent resident), you can obtain a name change certificate.

You need either one of these certificates to update things like your passport and other official forms of I.D. They can also be provided to banks, insurance companies, and government agencies as proof of identity.

A name change costs $170. The fee for a new certificate recording the name change is $33, but postage will be a little more (usually $5). Please note that you can access many of our national public services with a chosen name, for example, in most regions you don’t need to legally change your name for it to show on your library card!

Changing your sex/gender markers

As of June 15 2023, you no longer need to prove that you have undertaken medical treatment to align your registered sex with your gender. You can now self-identify and amend sex on your own birth certificate, replacing the previous Family Court application process. There are three ways to doing this in Aotearoa:

  1. You are NZ-born i.e. your birth was registered in Aotearoa, you can change the registered sex on your birth certificate.

  2. If you were born outside ofNZ but hold NZ citizenship, you can obtain an evidentiary certificate. 

  3. If you are applying for citizenship either by grant or descent, you can request your citizenship certificate to show your preferred gender.

To reiterate: your sex and/or gender markers can ONLY be changed in Aotearoa if your birth was registered here or you are a citizen. If your birth was registered outside New Zealand and you want to make changes to your overseas birth certificate, you need to seek advice from your country of birth.

How to change your name
and your sex / gender markers

In Aotearoa, you can change both your name and sex/gender markers at the same time if: 

  • You are NZ-born i.e. your birth was registered in Aotearoa and you have an NZ birth certificate, or

  • You have NZ citizenship

To reiterate: your details can ONLY be changed in Aotearoa if your birth was registered here or you are a citizen. 

If your birth was registered outside New Zealand and you want to make changes to your overseas birth certificate, you need to seek advice from your country of birth.

If you hold a different citizenship then you must seek advice from that nation.
