New Zealand First is a conservativepolitical party in New Zealand founded in July 1993, following the 19 March 1993 resignation of its leader and founder, Winston Peters, from the then-governing National Party. It has formed governments with both major parties in New Zealand: first with the National Party in 1996, and then with the Labour Party in 2005.

Commentators dispute the appropriate classification of the party on the traditional political spectrum, but New Zealanders might arguably associate it with advocacy of senior citizens' benefits, and opposition to immigration, especially from Asia.

The party held seats in the House of Representatives of New Zealand from its formation in 1993 until 2008, when it failed to gain enough party votes to retain representation. However, in the 2011 election, New Zealand First gained 6.59% of the total party vote, entitling it to eight MPs in the House.

The party sits on the cross-benches and during the 50th New Zealand Parliament tended to vote with the Opposition against Government policies.
