List of political parties in New Zealand

New Zealand national politics have featured a pervasive party system since the early 20th century. Usually, all members of Parliament's unicameral House of Representatives belong to a political party. Independent MPs do not occur often.

While two major parties have dominated the New Zealand national political landscape for decades, the introduction of proportional representation in 1996 led to a more multi-party state, as smaller parties can now reasonably expect to gain seats in government. Currently (as of July 2020), five parties have representatives in Parliament.
