About elections in New Zealand
I'm Bartłomiej Paruzel, and I built ElectioMap to map national elections around the world. This is the New Zealand hub on ElectioMap — it brings together the 4 New Zealand elections I cover, each with the official results, vote and turnout shares to two decimal places, and an interactive map you can explore region by region.
New Zealand (Aotearoa) is a parliamentary democracy and constitutional monarchy in the South Pacific, and one of the world's oldest continuous democracies — it was the first self-governing country to grant women the vote, in 1893. Legislative power rests with a single chamber, the House of Representatives, which normally has 120 members elected for three-year terms; there is no upper house (the appointed Legislative Council was abolished in 1951). The monarch — King Charles III — is a ceremonial head of state represented by the Governor-General, while executive power lies with a prime minister and cabinet drawn from, and accountable to, the House. Since 1996 New Zealand has used mixed-member proportional representation (MMP), adopted by referendum to replace first-past-the-post. Each voter casts two votes: a party vote, which determines each party's overall share of seats and is therefore the decisive figure, and an electorate vote for a local MP elected by first-past-the-post. Around 72 members are elected from single-member electorates — including 7 Māori electorates, reserved seats that voters of Māori descent may choose to enrol for — and the remainder from closed party lists that top each party up to its proportional entitlement. To win list seats a party must clear a threshold of 5% of the nationwide party vote or win at least one electorate; parties that win more electorates than their party vote warrants create "overhang" seats, which is why Parliament occasionally exceeds 120 members. Because no party usually wins an outright majority, governments are normally coalitions or minority administrations negotiated after the vote — a process in which a small party can hold the balance of power, as New Zealand First did in 2017 and 2023. New Zealand politics is dominated by two parties: the centre-right National Party (associated with blue) and the centre-left Labour Party (red). Around them sit the Greens (Labour's usual partner), the free-market ACT party (National's ally), the populist New Zealand First led by veteran Winston Peters, and Te Pāti Māori (the Māori Party). National governed from 2008 to 2017 under John Key and Bill English; Labour's Jacinda Ardern led a coalition from 2017, won an outright majority in the 2020 pandemic election — the first under MMP — and resigned in 2023, handing over to Chris Hipkins; National's Christopher Luxon then formed a three-party coalition with ACT and New Zealand First after the 2023 election. New Zealand also makes periodic use of referendums, most recently in 2020 on legalising euthanasia (passed) and recreational cannabis (narrowly rejected), held alongside the general election. Elections are run by the independent Electoral Commission, and official results are published at electionresults.govt.nz. This page collects New Zealand general-election results since 2017, together with the 2020 referendums, each with an interactive map of the party vote by region.
Each election listed here has its own page with the full breakdown by party or candidate and an interactive map of the result.
Every figure on ElectioMap is taken from the official electoral authority for New Zealand — the national election commission or equivalent body that certifies the count. I enter vote and turnout percentages exactly as published, to two decimal places and without rounding, and show seat totals wherever a chamber is being filled. When ElectioMap covers an election live, the page updates automatically as official figures are released. For the full sourcing and update policy, see Data & Methodology and the Editorial Policy.
