About this election
The electoral system
New Zealand elects its single-chamber House of Representatives by mixed-member proportional representation (MMP), adopted in 1996. Each voter casts two votes: a party vote, which determines the overall proportional share of seats, and an electorate vote for a local MP elected by first-past-the-post. In 2017, 71 members were elected from single-member electorates (including 7 Māori electorates) and the remaining 49 from closed party lists used to top parties up to their proportional entitlement. A party must win at least 5% of the nationwide party vote, or one electorate seat, to enter Parliament — which is why the party vote is the headline figure on the bars above. Voting is voluntary; turnout was 79.8%.
