How New Zealand actually works, voting

Voting, how New Zealand actually elects people

Two separate machines do the electing: the Electoral Commission runs national elections under the Electoral Act 1993, and each council's electoral officer runs local ones under the Local Electoral Act 2001. They share the enrolment roll and almost nothing else, different ballots, different counting, and in Christchurch's case a ballot that arrives by post rather than a polling booth.

Enrolling

Enrolment is compulsory for everyone eligible, 18 or over, a New Zealand citizen or resident, and living here. Voting itself is not compulsory. One quiet distinction worth knowing: permanent residents can vote, New Zealand is one of very few countries where you don't need citizenship for the national franchise. Enrol or update at vote.nz; it can be done up to and on election day itself.

Voters of Māori descent choose between the general roll and the Māori roll, the choice decides whether your electorate vote goes toward a general or a Māori electorate seat at general elections. The rolls can be switched almost any time except the few months before an election.

Two systems

General elections happen roughly every three years on a Saturday, at polling places, under MMP, two ticks, one for your local MP and one for the party. The full mechanics get their own page: how MMP works.

The next general election is Saturday 7 November 2026, Electoral Commission, key dates.

Local elections happen every three years in October, the next are October 2028, and there is no polling day at all: papers arrive by post, you have about a month to return them, and posting early is the only way to be sure they arrive in time. Each council picks its counting method: first-past-the-post (most ticks wins, what Christchurch uses) or STV (ranked preferences, used by Dunedin, Wellington and others, and by all district health board elections when those existed).

What the Christchurch ballot elects

One envelope, several contests: the mayor (city-wide), 16 councillors elected by ward, members of the city's community boards, and, separately, Environment Canterbury regional councillors, who do have Māori constituency seats. Property owners who live outside the city but pay rates here can also enrol on the ratepayer roll and vote in the district where the property sits.

Turnout is the honest part of the story: about 37.8% of enrolled Christchurch voters returned papers in 2025, typical for a postal local election, and a fraction of general-election turnout.

The 2025 result

On 11 October 2025 Phil Mauger was re-elected mayor, 60,137 votes (55.96%) against Sara Templeton's 40,533, with six other candidates splitting the rest. 16 ward councillors were elected alongside: seven independents, seven for The People's Choice / Labour, and two Independent Citizens, CCC, final result (PDF).

One thing the ballot didn't carry: a Māori-ward referendum. Forty-two councils held binding polls on whether to keep Māori wards created since 2021, 24 voted to remove them, but Christchurch has no Māori ward, after mana whenua told the council the direct iwi-council relationship served them better than a seat on it, Newstalk ZB.

The language

Enrolment

Registration on the electoral roll, compulsory for the eligible, and the thing that makes a ballot findable.

FPP

First-past-the-post, most ticks wins; Christchurch's local counting system.

STV

Single transferable vote, ranked preferences with surplus transfer; the other local option councils may choose.

Postal voting

The only local-election channel, papers posted out weeks ahead, returned by post or council drop-box, no polling day.

Ward

A council electorate, Christchurch's 16 councillors come in by ward, the mayor city-wide.

Ratepayer roll

The non-resident franchise, own rateable property in a district you don't live in and you may enrol to vote there too.

Māori roll

The electorate roll voters of Māori descent may choose instead of the general roll, decides which electorate seats your vote contests.

Citizens-initiated referendum

A petition-forced national poll, real but non-binding, unlike the binding council polls the 2024 Māori-ward law required.

The Canterbury of it

For nine years the ballot here was missing a line. In 2010 Parliament dismissed the elected Canterbury Regional Council, over failures in freshwater management and consent deadlines, replaced it with Crown-appointed commissioners, and cancelled the region's 2010 and 2013 elections Environment Canterbury (Temporary Commissioners and Improved Water Management) Act 2010, legislation.govt.nz. The return came in stages: a 2016 Act produced a hybrid council of seven elected and six appointed members, and only the October 2019 election restored a fully elected regional council Environment Canterbury (Transitional Governance Arrangements) Act 2016 Beehive, appointed members announced 2016. No other New Zealand council has spent that long under appointees.

The ward lines on the same ballot are Christchurch's own arithmetic: the Representation Commission draws the parliamentary map, but wards and community-board boundaries are the council's to set under the Local Electoral Act, with a representation review required at least every six years, 16 single-councillor wards since the 2016 review.
