Change the gender on your birth certificate
You need to apply to the Family Court for a declaration before you can change the gender on your NZ birth certificate. If your application is successful, the Family Court will notify Births, Deaths and Marriages.
Who can do it
The Family Court can make a declaration if you’re living with a different gender identity than the one on your birth certificate and you’ve had medical treatment (not necessarily full reconstructive surgery) to change your gender.
You must have been born in New Zealand to change your sex on your NZ birth certificate.
You can only change the sex on your birth certificate to ‘indeterminate’ if your sex was indeterminate when you were born, but was wrongly recorded as male or female. You should contact Births, Deaths and Marriages to make this change.
If you're under 18
You can only apply if you're in a marriage, civil union, or de facto relationship. Otherwise, your legal guardian can apply on your behalf.
How to apply
Complete the forms for changing gender, then deliver them or mail them to your nearest court.
A lawyer can help you apply. If you can't afford a lawyer, you can apply for legal aid. You may have to pay back some or all of the legal aid you get.
If you're applying on behalf of your child
You can apply to the Family Court for a declaration about a child's gender identity if you're the child's legal guardian.
The court will consider different issues than it does when making a declaration for an adult. A lawyer can discuss the process with you and help you apply.
What happens next
If your application is approved, Births, Deaths and Marriages will ask you to confirm the name you want on your birth certificate.
What it costs
It’s free to apply to change your gender on your birth record. You can also request a new birth certificate at this time, free of charge.
