Changing your name
Change your own name
You can change your own name in New Zealand if you’re 18 or over and a citizen or entitled to live here indefinitely.
Change your child's name
Usually, both parents need to agree to change a child's name, even if they're not together. Once your child is 16, you can't change their name without their consent.
Change your name on your driver licence
If you legally change your name, you don't have to replace your driver licence — but you can if you want to. You'll need to provide an original document that shows the change.
Change your name in your passport
If you want to change the name in your passport, you’ll need to apply for a new one. The name in your passport must be your officially registered name.
