The New Zealand Parliament passes the Homosexual Law Reform Act legalising homosexuality in New Zealand.

The New Zealand Parliament is the unicameral legislature of New Zealand, consisting of the Sovereign and the New Zealand House of Representatives. The King is usually represented by his governor-general. Before 1951, there was an upper chamber, the New Zealand Legislative Council. The New Zealand Parliament was established in 1854 and is one of the oldest continuously functioning legislatures in the world. It has met in Wellington, the capital of New Zealand, since 1865 and in its current building since 1922.

The Homosexual Law Reform Act 1986 is a New Zealand Act of Parliament that broadly legalised consensual sexual practices between men as well as consensual anal sex regardless of partners' gender. It removed the provisions of the Crimes Act 1961 that criminalised this behaviour. The legislation established a uniform age of consent, setting it at 16 for both same-sex and opposite-sex partners.

New Zealand lesbian, gay, bisexual, transgender, and queer (LGBTQ) rights are some of the most extensive in the world. The protection of LGBTQ rights is advanced, relative to other countries in Oceania, and among the most liberal in the world, with the country being the first in the region to legalise same-sex marriage.
