New Zealand electorates
Voting districts for election to the New Zealand Parliament From Wikipedia, the free encyclopedia
An electorate or electoral district (Māori: rohe pōti[1]) is a geographic constituency used for electing a member (MP) to the New Zealand Parliament.[2] The size of electorates is determined such that all electorates have approximately the same electoral population.
Before 1996, all MPs were directly chosen for office by the voters of an electorate. Thereafter, New Zealand's electoral system provides that some (in practice, the majority) of the usually 120 seats in Parliament are filled by electorate representatives with the remainder being filled from party lists in order to achieve proportional representation among parties. The number of electorates changes periodically, in line with national population growth. Starting from the 2020 general election, there are 72 electorates including the Māori electorates.
Terminology
The Electoral Act 1993 refers to electorates as "electoral districts".[2] Electorates are informally referred to as "seats" (Māori: tūru), but technically the term seat refers to an elected member's place in Parliament.[3][n 1]

Under first-past-the-post (1853–1993)
The electoral boundaries for the inaugural 1853 general election were drawn up by the governor, George Grey, with the authority for this coming from the New Zealand Constitution Act 1852.[4] After the initial election, there were eight redivisions carried out by members of the general assembly (as the lower house was known at the time). These revisions were a mixture of minor and major boundary adjustments. In 1887, the responsibility for reshaping electorates was given to a Representation Commission and that arrangement has remained to this day. Up until 1981, the boundaries of the Māori electorates were determined by the governor or governor-general, when that responsibility was also transferred to the Representation Commission.[5]
Since the Representation Act 1900 and 1902 electoral redistribution, the number of electorates had been fixed at 80. Slower growth in the population of the South Island compared to the North Island meant the number of South Island electorates, once near-equal to the North, was decreasing and the geographic size of those electorates was growing. The 80-electorate cap was removed in 1969 and instead the number of South Island electorates fixed at 25. Thereafter, the number of electorates steadily increased, peaking with 99 members elected in 1993, of whom 74 were elected from North Island electorates.[6]
Elections for the House of Representatives in the 1850s modelled the electoral procedures used for the British House of Commons, which at that time featured both single-member electorates (electorates returning just one MP) and multi-member electorates (electorates returning more than one MP).[7] Each electorate was allocated a different number of MPs (up to three) in order to balance electoral population differences. All electorates used a plurality voting system, except between 1908 and 1913 when a two-round voting system was employed.[8][9]
Electorate boundaries were not always drawn to provide for proportional representation between communities. From 1881, a special country quota meant that rural seats could contain fewer people than urban seats, preserving improportionality by over-representing the rural electoral population (mostly made up by farmers). The country quota inflated the number of the electoral population outside of cities and certain towns by some percentage. The quota was at first 33% (1881–1887), then briefly 18% (1887–1889), and 28% for the remaining period (1889–1945).[10][5] For the 1905 election, the multi-member electorates were abolished. The country quota persisted until 1945.[7] A system of Māori electorates providing indigenous representation was established in 1867 but these were not drawn in proportion to their general electorate counterparts until the election of the 45th New Zealand Parliament in 1996.
Under mixed-member proportional representation (since 1996)
| Election Year | Parliament | North Island electorates | Māori electorates | Total |
|---|---|---|---|---|
| 1996 | 45th | 44 | 5 | 65 |
| 1999 | 46th | 45 | 6 | 67 |
| 2002 | 47th | 46 | 7 | 69 |
| 2005 | 48th | 46 | 7 | 69 |
| 2008 | 49th | 47 | 7 | 70 |
| 2011 | 50th | 47 | 7 | 70 |
| 2014 | 51st | 48 | 7 | 71 |
| 2017 | 52nd | 48 | 7 | 71 |
| 2020 | 53rd | 49 | 7 | 72 |
| 2023 | 54th | 49 | 7 | 72 |
| 2026 | 55th | 48 | 7 | 71 |
Since the introduction of the mixed-member proportional system at the 1996 election, there have been at least 120 MPs and the number of South Island electorates has been fixed at 16. Like under the previous system, the number of North Island electorates is calculated in proportion to the South Island and that number has risen from 44 to a peak of 49 in 2020 and 2023.[11][12][13] The new electoral system also provides for the number of Māori electorates to be calculated proportionally, and these have sat at 7 since 2002. In October 2024, Statistics New Zealand announced that population changes necessitated reducing the number of North Island general electorates by one, returning the number of North Island general electorates to 48.[14]
Because the number of MPs is fixed at a minimum of 120, adding additional electorates means there are fewer seats available for list MPs.[15] List MP seats are assigned proportionally to parties that win at least one electorate or receive at least 5% of the party vote. However, additional list MPs may be elected if overhang seats are required due to a party winning more electorates than its party vote share entitles it; the total number of members may therefore be more than 120.[16] In 2005 and 2011, 121 members were elected; 122 members were elected in 2008; 123 members were elected in 2023.[17][18]
Representation Commission
The Representation Commission has determined general electorate boundaries since 1881.[5][19] These days, the Commission consists of:
- Four government officials—the Government Statistician, the Surveyor-General, the Chief Electoral Officer, and the Chairperson of the Local Government Commission.
- A representative of the governing party or coalition, and a representative of the opposition bloc.
- A chairperson (often a judge) nominated by the other members (with the exception of Chairperson of the Local Government Commission).[19]
The Representation Commission reviews electorate boundaries after each New Zealand census, which normally occurs every five years.[2] The Electoral Act 1993 stipulates that the South Island is to have 16 general electorates, and dividing the number of persons in the South Island's general electoral population by 16 determines the South Island Quota.[n 2] This quota is then used to calculate the number of Māori electorates[n 3] and to determine the number of North Island electorates.[n 4]
The number of Māori electorates is calculated by dividing the Māori electoral population (MEP) of New Zealand by the South Island Quota. Māori voters may choose to either be represented in a Māori electorate or a general electorate, so the MEP is influenced by the number of Māori who opt for Māori electorate representation. Māori voters who choose to be represented in a general electorate are included in the General electoral population (GEP) of either the South Island or North Island. The number of North Island electorates is calculated by applying the South Island Quota to the North Island GEP.[20] In this way, all three types of electorates will represent similar populations. Electorates may vary by no more than 5% of the average electoral population size.[2]
In drawing new electorate boundaries, the Representation Commission must give due consideration to existing boundaries, communities of interest, facilities of communications, topographical features, and projected variation in population. Regard is often had for local authority boundaries. The Commission may abolish electorates and create new ones in their place. Except for Māori electorates, electorates must be wholly situated on either the North Island or South Island. Populations on other islands, such as Stewart Island / Rakiura and the Chatham Islands, are included by convention in electorates that provide access to the mainland, latterly Invercargill and Rongotai, respectively.
Naming conventions
The Representation Commission determines the names of each electorate following the most recent census.[19] An electorate may be named after a geographic region, landmark (e.g. a mountain) or main population area. The Commission adopts compass point names when there is not a more suitable name. The compass point reference usually follows the name of the main population centre, e.g. Hamilton East.
Special electorates
Summarize
Perspective
Two types of special electorates have been used.
Goldminers' electorates
Goldminers' electorates were created for participants in the Otago gold rush. Goldminers did not usually meet the residency and property requirements in the electorate they were prospecting in, but were numerous enough to warrant political representation. Three goldminers' electorates existed, the first began in 1863 and both ended in 1870.
Māori electorates
Much more durable have been the Māori electorates, created in 1867 to give separate representation to Māori. Although originally intended to be temporary, they came to function as reserved positions for Māori until 1967, ensuring that there would always be a Māori voice in Parliament. In 1967 the reserved status of the Māori seats was removed, allowing non-Māori to stand in the Māori electorates. Until 1993 the number of Māori electorates was fixed at four, significantly under-representing Māori in Parliament. In 1975 the definition of who could opt to register on either the general or the Māori roll was expanded to include all persons of Māori descent.[21] Previously all persons of more than 50% Māori ancestry were on the Māori roll while persons of less than 50% Māori ancestry were required to enrol on the then European roll. Only persons presumed to have equal Māori and European ancestry (so-called half-castes) had a choice of roll.[22]
Since the introduction of MMP in 1996, the number of seats can change with the number of Māori voters who choose to go on the Māori roll rather than the general roll. In 1996, there were five Māori electorates. For the 1999 election, this increased to six electorates. Since the 2002 election, the number of Māori electorates has stayed constant at seven.[23]

- Historically the only way to gain a seat in Parliament was to win an electorate, but under the present MMP system, MPs selected from party lists—called list MPs—are able to gain a seat without representing an electorate.
