Same-sex marriage — New Zealand

Marriage since 2013, adoption law still lagging behind it by nearly seventy years.

The legal framework

New Zealand opened marriage in August 2013 by a comfortable parliamentary majority, the first country in the Asia-Pacific region to do so. Civil unions, created in 2004, remain available to all couples. The weak point is adoption: the governing Act dates from 1955, was written for a different family model, and successive reviews have called for its replacement.

New Zealand's 2013 vote is remembered for the scene in the debating chamber — the public gallery singing after the result — and for the speed of the change: from civil unions in 2004 to marriage in nine years. Adoption law has simply not kept pace, which is why so many practical questions here are adoption questions rather than marriage questions.

In practice

Cost and coverage

A marriage licence costs around one hundred and fifty New Zealand dollars and a registry ceremony a similar amount; a celebrant charges more. Publicly funded fertility treatment exists subject to eligibility criteria.

Recent changes

Reform of the 1955 Adoption Act has been through public consultation, with proposals to recognise a wider range of family arrangements, but no replacement statute has yet been enacted.

Where to go

Worth knowing

The 1955 Adoption Act is the recurring problem: it produces an all-or-nothing outcome, sits awkwardly with assisted reproduction, and has survived several announced reforms.

Frequently asked questions

Can foreigners marry in New Zealand?

Yes, there is no residence requirement; a licence must be obtained from a registrar beforehand. This has made the country a destination for couples from jurisdictions where marriage is not available.

Why is adoption still an issue?

Because the Adoption Act dates from 1955 and predates both marriage equality and assisted reproduction. It forces intended parents through surrogacy to adopt their own child, and it offers no intermediate status. Reform has been consulted on repeatedly without being enacted.
