Change your child's name
You can change your child’s name in New Zealand if they are 15 or under and a citizen or entitled to live here indefinitely. Once your child is 16, they can apply themselves with your consent.
Overview
You can apply to change your child’s name if:
- they are 15 or under, and
- they were born here, they are a New Zealand citizen, or they are entitled to live here indefinitely.
Usually, all the child’s parents or legal guardians need to sign the statutory declaration section of the form to change the child’s name — even if the parents are not together.
If all parents or guardians cannot sign
If a parent or legal guardian is not able to sign the statutory declaration section of the form, you need to explain why. You also need to provide evidence if they are:
- deceased
- missing and you have tried to find them, or
- of unsound mind or unable to act because of a medical condition.
Sometimes the Family Court will allow 1 guardian to act alone to change a child’s name. In this case, include copies of the original papers issued by the court with your application. Do not post or courier original documents.
Update the sex on your child's birth certificate
If you also want to update the sex marker on your child's New Zealand birth certificate, this is a different process to just changing their name. You can apply to change both using the same form.

What you can change your child’s name to
You can change all or part of your child’s name.
Their new name has to consist of 1 surname and 1 or more other names. If you have religious, philosophical or cultural reasons to have only one name, you need to include a letter of explanation with your application.
The new name might not be accepted if it’s:
- offensive
- longer than 70 characters, including spaces
- an official title or rank, or resembles one (for example, Justice, King, Prince, Princess, Royal)
- spelled with numbers or symbols (for example, V8).
