The legal framework

Same-sex marriage has been legal since 2013, and the Human Rights Act has prohibited discrimination on grounds of sexual orientation since 1993. The Conversion Practices Prohibition Legislation Act came into force in 2022, creating offences where practices are performed on a young person or cause serious harm. Since 2023 people have been able to change the sex recorded on their birth certificate by self-identification.

New Zealand legislated marriage equality in 2013, banned conversion practices in 2022 with criminal penalties where harm is caused to a minor or a person lacking capacity, and moved to self-identification for the sex marker on birth certificates in 2021 — an administrative process without medical evidence. The Human Rights Act covers sexual orientation, and gender identity is treated as covered through sex discrimination.

Where to go

Worth knowing

The 2022 Act distinguishes between prohibited practices and ordinary expressions of religious belief or clinical advice. It is aimed at directed attempts to change a person, not at conversations.

Frequently asked questions

How does changing a birth certificate work?

By self-identification through an administrative application to the registrar, without medical evidence or a court process, since the 2021 amendment. A young person can apply with the support of a guardian. This replaced a Family Court procedure that required evidence of medical treatment.

What does the conversion practices ban cover?

It prohibits practices directed at changing or suppressing a person's sexual orientation or gender identity, with criminal offences where the practice is performed on someone under eighteen or lacking capacity, or where serious harm results, and a civil complaints route to the Human Rights Commission otherwise.
