The 45th New Zealand Parliament was a term of the Parliament of New Zealand. Its composition was determined by the 1996 election, and it sat until the 1999 election.

The 45th Parliament was notable in that it was the first to be elected under the new MMP electoral system, a form of proportional representation. It was also notable for the fact that it was the first New Zealand Parliament to have an Asian person, Pansy Wong, elected to it. The difference between the 45th Parliament and its predecessor were considerable — the 44th Parliament had opened with only four seats being held by minor parties, but at the opening of the 45th Parliament, minor parties held thirty-nine seats. Because of the considerably altered balance of power in Parliament, neither of the two major parties could govern alone, and New Zealand First, the largest of the four other parties in Parliament, was put in the position of "kingmaker". In the end, New Zealand First opted for a coalition with the National Party which had governed in the previous Parliament, marking the first coalition government in New Zealand for over half a century.^[1] The Labour Party continued in Opposition.

The 45th Parliament consisted of one hundred and twenty representatives. Sixty-five of these representatives were chosen by geographical electorates, including five special Maori electorates. The remainder were elected by means of party-list proportional representation under the MMP electoral system.

Notes

• ^1 New Zealand First initially entered into a coalition with the National Party, which broke down in 1998. Half the party resigned and became independents, while the other half remained with the party and joined the opposition.
• ^2 A collection of small parties were founded and received representation by independent MPs who were formerly with New Zealand First and Alliance. They supported the National Party in government.
• ^3 ACT and United Future extended support to the National Party, giving the government a slim majority in parliament.
• ^4 The Green Party sat in Parliament under the banner of the Alliance Party.
• The Working Government majority is calculated as all Government MPs less all other parties.
