The politics of New Zealand function within a framework of an independent, unitary, parliamentary democracy. The system of government is based on the Westminster system, and the legal system is modelled on the common law of England. New Zealand is a constitutional monarchy in which King Charles III is the sovereign and head of state, while his prime minister serves as the head of government.
Mixed-member proportional representation is a mixed electoral system in which votes are cast for both local elections and also for overall party vote tallies, which are used to allocate additional members to produce or deepen overall 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.
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.
The House of Representatives is the sole chamber of the New Zealand Parliament. The House passes laws, provides ministers to form Cabinet, and supervises the work of government. It is also responsible for adopting the state's budgets and approving the state's accounts.
The Cabinet of New Zealand is the New Zealand Government's body of senior ministers, accountable to the New Zealand Parliament. Cabinet meetings, chaired by the prime minister, occur once a week; in them, vital issues are discussed and government policy is formulated. Cabinet is also composed of a number of committees focused on specific areas of governance and policy. Though not established by any statute, Cabinet wields significant power within the New Zealand political system, with nearly all government bills it introduces in Parliament being enacted.
Sir Geoffrey Winston Russell Palmer is a New Zealand lawyer, legal academic, and former politician, who was a member of Parliament from 1979 to 1990. He served as the 33rd prime minister of New Zealand for a little over a year, from August 1989 until September 1990, leading the Fourth Labour Government. As minister of justice from 1984 to 1989, Palmer was responsible for considerable reforms of the country's legal and constitutional framework, such as the creation of the Constitution Act 1986, New Zealand Bill of Rights, Imperial Laws Application Act, and the State Sector Act. He served as president of the New Zealand Law Commission, from 2005 to 2010.
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. The most recent general election took place on 14 October 2023.
Parallel voting is a type of mixed electoral system in which representatives are voted into a single chamber using two or more different systems, most often first-past-the-post voting (FPTP) with party-list proportional representation (PR). It is the most common form of mixed member majoritarian representation (MMM), which is why these terms are often used synonymously with each other. In some countries, parallel voting is known as the supplementary member (SM) system, while in academic literature it is sometimes called the superposition method within mixed systems.
The Electoral Commission is an independent Crown entity set up by the New Zealand Parliament. It is responsible for the administration of parliamentary elections and referendums, promoting compliance with electoral laws, servicing the work of the Representation Commission, and the provision of advice, reports and public education on electoral matters. The commission also assists electoral agencies of other countries on a reciprocal basis with their electoral events.
An electorate or electoral district is a geographic constituency used for electing a member (MP) to the New Zealand Parliament. The size of electorates is determined such that all electorates have approximately the same population.
The constitution of New Zealand is the sum of laws and principles that determine the political governance of New Zealand. Unlike many other nations, New Zealand has no single constitutional document. It is an uncodified constitution, sometimes referred to as an "unwritten constitution", although the New Zealand constitution is in fact an amalgamation of written and unwritten sources. The Constitution Act 1986 has a central role, alongside a collection of other statutes, orders in Council, letters patent, decisions of the courts, principles of the Treaty of Waitangi, and unwritten traditions and conventions. There is no technical difference between ordinary statutes and law considered "constitutional law"; no law is accorded higher status. In most cases the New Zealand Parliament can perform "constitutional reform" simply by passing acts of Parliament, and thus has the power to change or abolish elements of the constitution. There are some exceptions to this though – the Electoral Act 1993 requires certain provisions can only be amended following a referendum.
The Royal Commission on the Electoral System was formed in New Zealand in 1985 and reported in 1986. The decision to form the Royal Commission was taken by the Fourth Labour government, after the Labour Party had received more votes, yet it won fewer seats than the National Party in both the 1978 and 1981 elections. It was also a reaction to the power displayed by Prime Minister Robert Muldoon, whose action of illegally abolishing the Superannuation scheme in 1975 without any repercussions highlighted the need to distribute power in a more democratic way. The Royal Commission's report Towards a Better Democracy was instrumental in effecting New Zealand to change its electoral system from first-past-the-post to mixed member proportional.
The New Zealand electoral system has been 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 MMP, 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 New Zealand Government is the central government through which political authority is exercised in New Zealand. As in most other parliamentary democracies, the term "Government" refers chiefly to the executive branch, and more specifically to the collective ministry directing the executive. Based on the principle of responsible government, it operates within the framework that "the [King] reigns, but the government rules, so long as it has the support of the House of Representatives". The Cabinet Manual describes the main laws, rules and conventions affecting the conduct and operation of 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 British settlers. The first New Zealand Constitution Act was passed in 1852, and the first parliamentary elections were held the following year.
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.
