The 1996 New Zealand general election was held on 12 October 1996 to determine the composition of the 45th New Zealand Parliament. It was notable for being the first election to be held under the new mixed-member proportional (MMP) electoral system, and produced a parliament considerably more diverse than previous elections. Under the new MMP system, 65 members were elected in single-member districts by first-past-the-post voting, while a further 55 "top-up" members were allocated from closed lists to achieve a proportional distribution based on each party's share of the nationwide party vote.

The New Zealand electoral system has been mixed-member proportional (MMP) since the 1996 election. MMP was introduced following a referendum in 1993. It replaced the first-past-the-post (FPP) system New Zealand had previously used for most of its history. Under MMP, New Zealanders have two secret ballot votes to elect members of Parliament (MPs). The first vote is for a candidate from an electorate, a geographic electoral district. The second is the party vote for the political party the voter wants to form the government.
