New Zealand 54th parliament sat for its final time last week ahead of a November 7 election. Polls indicate that no one party will emerge as a clear winner with neck-to-neck support for both left and right blocs.

The winning group would be decided based on a mixed-member proportional (MMP) electoral system, which has made coalitions the norm in New Zealand since it was introduced three-decades ago.

All governments under MMP have been coalitions of the centre-left Labour or centre-right National with the support of smaller parties, except in 2020 when the Labour government swept to power after successfully managing the early months of the coronavirus (Covid-19) outbreak.

Under MMP, voters cast two votes: one for their preferred constituency candidate and one for a party.

The candidate with the most votes wins and becomes an MP, while the party vote decides how many seats each party gets in parliament.

The winning candidates of the country’s 71 constituencies take their seats automatically, while the remaining seats are filled from party lists, allocated to match each party’s share of the nationwide vote.

There are expected to be about 49 party list seats in this election, though that number can change.

Political parties must get at least 5% of the party vote or win at least one electorate seat to get any seats in Parliament.

A party or coalition can form a government when it secures a majority in the single-chamber parliament, usually at least 61 of 120 seats.

Due to the nature of the MMP system that was first used in New Zealand in 1996, minor parties often play a decisive role.

The 2017 election, National won 56 seats, more than Labour’s 46, but failed to assemble a majority.

Labour formed a government through a coalition with New Zealand First and the Green Party.

Parliament normally has 120 seats, but extra seats can be added when a party wins more electorate seats than its share of the nationwide party vote would otherwise entitle it to.

This happened after the 2023 election.

Seven of the electorate seats are Maori electorates, reserved for voters who choose to enrol on the Maori electoral roll.
