Proportional representation (PR) refers to any type of electoral system under which subgroups of an electorate are reflected proportionately in the elected body. The concept applies mainly to political divisions among voters. The essence of such systems is that all votes cast – or almost all votes cast – contribute to the result and are effectively used to help elect someone. Under other election systems, a bare plurality or a scant majority are all that are used to elect candidates. PR systems provide balanced representation to different factions, reflecting how votes are cast.
The additional-member system (AMS) is a two-vote seat-linkage-based mixed electoral system used in the United Kingdom in which most representatives are elected in single-member districts (SMDs), and a fixed number of other "additional members" are elected from a closed list to make the seat distribution in the chamber more proportional to the votes cast for party lists. It is distinct from using parallel voting for the list seats in that the "additional member" seats are awarded to parties taking into account seats won in SMDs – these are ignored under parallel voting.
Mixed-member proportional representation is a type of representation provided by some mixed electoral systems which combine local winner-take-all elections with a compensatory tier with party lists, in a way that produces proportional representation overall. Like proportional representation, MMP is not a single system, but a principle and goal of several similar systems. Some systems designed to achieve proportionality are still called mixed-member proportional, even if they generally fall short of full proportionality. In this case, they provide semi-proportional representation.
The New Zealand Parliament is the unicameral legislature of New Zealand, consisting of the Sovereign (King-in-Parliament) and the New Zealand House of Representatives. The King is usually represented by his governor-general. Before 1951, there was an upper chamber, the New Zealand Legislative Council. The New Zealand Parliament was established in 1854 and is one of the oldest continuously functioning legislatures in the world. It has met in Wellington, the capital of New Zealand, since 1865 and in its current building since 1922.
Electoral reform in New Zealand has been a political issue in the past as major changes have been made to both parliamentary and local government electoral systems. A landmark reform was the mixed-member proportional (MMP) system, implemented in 1996 following a public referendum.
New Zealand is a representative democracy in which members of the unicameral New Zealand Parliament gain their seats through elections. General elections are usually held every three years; they may be held at an earlier date at the discretion of the prime minister, but that usually only happens in the event of a vote of no confidence or other exceptional circumstances. A by-election is held to fill an electorate vacancy arising during a parliamentary term. Election day is always a Saturday, but advance voting is allowed in the lead-up to it. The most recent general election took place on 14 October 2023.
In political science, parallel voting or superposition refers to the use of two or more electoral systems to elect different members of a legislature. More precisely, an electoral system is a superposition if it is a mixture of at least two tiers, which do not interact with each other in any way; one part of a legislature is elected using one method, while another part is elected using a different method, with all voters participating in both. Thus, the final results can be found by calculating the results for each system separately based on the votes alone, then adding them together. A system is called fusion or majority bonus, another independent mixture of two system but without two tiers. Superposition is also not the same as "coexistence", which when different districts in the same election use different systems. Superposition, fusion and coexistence are distinct from dependent mixed electoral systems like compensatory (corrective) and conditional systems.
The 1996 New Zealand general election was held on 12 October 1996 to determine the composition of the 45th New Zealand Parliament. It was significant for being the first election to be held under the new mixed-member proportional (MMP) electoral system, and produced a parliament considerably more diverse than previous elections. Under the new MMP system, 65 members were elected in single-member districts by first-past-the-post voting, while a further 55 "top-up" members were allocated from closed lists to achieve a proportional distribution based on each party's share of the nationwide party vote.
In New Zealand politics, Māori electorates, colloquially known as the Māori seats, are a special category of electorate that give reserved positions to representatives of Māori in the New Zealand Parliament. Every area in New Zealand is covered by both a general and a Māori electorate; as of 2020, there are seven Māori electorates. Since 1967, candidates in Māori electorates have not needed to be Māori themselves, but to register as a voter in the Māori electorates people need to declare that they are of Māori descent.
The New Zealand parliamentary electoral system has been based on the principle of mixed-member proportional (MMP) since the 1996 election. MMP was introduced following a referendum in 1993. It replaced the first-past-the-post (FPP) system New Zealand had previously used for most of its history. Under the MMP system, New Zealanders have two secret ballot votes to elect members of Parliament (MPs). The first vote is for a candidate from an electorate, a geographic electoral district. The second is the party vote for the political party the voter wants to form the government.
The Fourth National Government of New Zealand was the government of New Zealand from 2 November 1990 to 27 November 1999. Following electoral reforms in the 1996 election, Jim Bolger formed a coalition with New Zealand First. Following Bolger's resignation, the government was led by Jenny Shipley, the country's first female prime minister, for the final two years.
Voting in New Zealand was introduced after colonisation by Britain. The first New Zealand Constitution Act was passed in 1852, and the first parliamentary elections were held the following year.
Te Tai Tokerau is a New Zealand parliamentary Māori electorate that was created out of the Northern Maori electorate ahead of the first Mixed Member Proportional (MMP) election in 1996. It was held first by Tau Henare representing New Zealand First for one term, and then Dover Samuels of the Labour Party for two terms. From 2005 to 2014, it was held by MP Hone Harawira. Initially a member of the Māori Party, Harawira resigned from both the party and then Parliament, causing the 2011 by-election. He was returned under the Mana Party banner in July 2011 and confirmed at the November 2011 general election. In the 2014 election, he was beaten by Labour's Kelvin Davis, ending the representation of the Mana Party in Parliament.
The Electoral Reform Coalition (ERC) is a group advocating electoral reform in New Zealand. It was founded in 1986. The group has been reformed as the Campaign for MMP to fight to retain Mixed-member proportional representation at the 2011 referendum on the issue.
The 2011 New Zealand voting system referendum was a referendum on whether to keep the existing mixed member proportional (MMP) voting system, or to change to another voting system, for electing Members of Parliament to New Zealand's House of Representatives. It was held on 26 November 2011 in conjunction with the 2011 general election.
Electoral reform is a change in electoral systems which alters how public desires are expressed in election results.
The 50th New Zealand Parliament was elected at the 2011 general election. It had 121 members, and was in place from December 2011 until September 2014, followed by the 2014 general election. The first sitting of the 50th Parliament was held on 20 December 2011, where members were sworn in and Lockwood Smith was elected Speaker of the House. This was followed by the speech from the throne on 21 December. John Key continued to lead the Fifth National Government. Following the resignation of Smith, David Carter was elected Speaker.
The dual-member mixed proportional (DMP) voting method is a mixed electoral system using a localized list rule to elect two representatives in each district. It is similar to other forms of mixed-member proportional representation, but differs from the better-known additional-member system in that all representatives are elected locally in small districts, rather than requiring separate list seats to be filled in large regional or nationwide districts. In the first step, one seat in each district is awarded to the candidate or party with the most votes, as with first-past-the-post voting rules. In the second step, underrepresented parties are assigned secondary seats in the districts in which they won the most votes, which creates an overall proportional result.
A referendum on electoral reform took place by mail-in ballot between October 22 and December 7, 2018, in the Canadian province of British Columbia. 61.3 percent of voters supported maintaining the first-past-the-post voting system rather than switching to a proportional representation voting system, which was supported by 38.7 percent of voters. This was British Columbia's third referendum on electoral reform, following ones in 2005 and 2009.
Mixed-member majoritarian representation (MMM) is type of a mixed electoral system combining winner-take-all and proportional methods, where the disproportional results of the winner-take-all part are dominant over the proportional component. Mixed member majoritarian systems are therefore categorized under semi-proportional representation, and are usually contrasted with mixed-member proportional representation (MMP) which aims to provide proportional representation compensation ("top-up") seats.
