The legal framework

The Marriage (Court Consent to Marriage of Minors) Amendment Act 2018 removed parental consent for 16 and 17 year olds and replaced it with Family Court approval, as a measure against forced marriage. Same-sex marriage was legalised in 2013, making New Zealand the first country in the Asia-Pacific region to do so.

In practice

Cost and coverage

Licence and certificate fees are modest.

Recent changes

Because the Property (Relationships) Act applies equally to de facto couples after three years, the legal significance of marrying is smaller in New Zealand than almost anywhere else.

Where to go

Worth knowing

Marriage and long cohabitation have nearly identical property consequences here. If you want a different outcome, the contracting-out agreement — not the wedding — is the document that matters. Civil union remains available and is not identical to marriage in every overseas context. If you will live abroad, marriage is usually recognised more widely.
