48th New Zealand Parliament

The 48th New Zealand Parliament was a term of the Parliament of New Zealand. Its composition was determined at a general election held on 17 September 2005. The new parliament met for the first time on 7 November 2005. It was dissolved on 3 October 2008.

The Labour Party and the Progressive Party, backed by New Zealand First and United Future, established a majority at the beginning the 48th Parliament. The Labour-led administration was in its third term. The National Party and ACT form the formal opposition to the government. Other non-government parties are the Greens (who promised to abstain on confidence and supply votes) and the Māori Party.

The 48th Parliament consists of 121 representatives. This represents an overhang of one seat, with the Māori Party having won one more electorates than its share of the vote would otherwise have given it. In total, sixty-nine of the MPs were chosen by geographical electorates, including seven Māori electorates. The remainder were elected by means of party-list proportional representation under the MMP electoral system.

All the Māori Party MPs tried to alter their Oath of office by adding references to the Treaty of Waitangi. They all had to retake their oaths.
