Uncodified national constitution

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. After decades of self governance, New Zealand gained full statutory independence from Britain in 1947. It is a constitutional monarchy with a parliamentary democracy. The monarch of New Zealand is the head of state – represented in the Realm of New Zealand by the governor general – and is the source of executive, judicial and legislative power, although effective power is in the hands of ministers drawn from the democratically elected New Zealand House of Representatives. This system is based on the "Westminster model", although that term is increasingly inapt given constitutional developments particular to New Zealand.

The New Zealand constitution is uncodified and is to be found in formal legal documents, in decisions of the courts, and in practices (some of which are described as conventions). It establishes that New Zealand is a constitutional monarchy, that it has a parliamentary system of government, and that it is a representative democracy. It increasingly reflects the fact that the Treaty of Waitangi is regarded as a founding document of government in New Zealand. The constitution must also be seen in its international context because New Zealand governmental institutions must increasingly have regard to international obligations and standards. The Constitution Act 1986 describes the three branches of Government in New Zealand: The Executive (the Executive Council, as the Cabinet has no formal legal status), the legislature (the House of Representatives and Sovereign in Parliament) and the judiciary (Court system).

As per the Constitution Act 1986, New Zealand is a constitutional monarchy, wherein the role of the reigning sovereign is both legal and practical. The underlying principle is democracy, with political power exercised through a democratically elected parliament – this is often stated as "The [monarch] reigns but the government rules so long as it has the support of the House of Representatives." Section 2(1) of the Act declares "The Sovereign in right of New Zealand" as head of state, with the monarch at the centre of a construct in which the power of the whole is shared by multiple institutions of government acting under the sovereign's authority. The monarch is a component of Parliament, and the Royal Assent is required to allow for bills to become law. In practice the monarch takes little direct part in the day to day functions of government; the decisions to exercise sovereign powers are delegated from the monarch, either by statute or by convention, to ministers of the Crown, or other public bodies, exclusive of the monarch personally. Moreover, as the monarch is not normally resident in the country, the sovereign's representative in and over the Realm of New Zealand is the governor general. such as the ability to dismiss the prime minister in exceptional cases. Section 3(1) of the Constitution Act states "Every power conferred on the Governor General by or under any Act is a royal power which is exercisable by the Governor General on behalf of the Sovereign, and may accordingly be exercised either by the Sovereign in person or by the Governor General". New Zealand has a legislature called the New Zealand Parliament, consisting of the King in Parliament and the House of Representatives. According to the principle of parliamentary sovereignty, Parliament may pass any legislation that it wishes. Since 1996, New Zealand has used the mixed member proportional (MMP) system, which is essentially proportional representation with single member seats (that can affect the proportionality of the House, but only to a limited degree). Seven electorates are currently reserved for members elected on a separate Māori roll. However, Māori may choose to vote in and to run for the non reserved seats, and several have entered Parliament in this way. The Cabinet, which is responsible to Parliament, exercises executive authority. The Cabinet forms the practical expression of a formal body known as the Executive Council. The prime minister, as the parliamentary leader of the political party or coalition of parties holding or having the support of a majority of seats in the House of Representatives, chairs the Cabinet. Section 6(1) of the Constitution Act 1986 states, "A person may be appointed and may hold office as a member of the Executive Council or as a Minister of the Crown only if that person is a member of Parliament". this is the principle of responsible government. New Zealand's judiciary is a hierarchy consisting of the Supreme Court of New Zealand, the Court of Appeal of New Zealand, the High Court of New Zealand, and the District Courts. These courts are all of general jurisdiction. There are several other courts of specialist jurisdiction, including the Employment Court, the Environment Court and the Māori Land Court, as well as the Family Court and the Youth Court, which operate as specialised divisions of the District Courts. There are also a number of specialised tribunals which operate in a judicial or quasi judicial capacity, such as the Disputes Tribunal, the Tenancy Tribunal and the Waitangi Tribunal.

New Zealand law has three principal sources: English common law; certain statutes of the United Kingdom Parliament enacted before 1947 (notably the Bill of Rights 1689); and statutes of the New Zealand Parliament. In interpreting common law, there is a rebuttable presumption in support of uniformity with common law as interpreted in the United Kingdom and related jurisdictions. Non uniformity arises where the New Zealand courts consider local conditions to warrant it or where the law has been codified by New Zealand statute. The maintenance of the Judicial Committee of the Privy Council in London as the final court of appeal and judges' practice of tending to follow British decisions, even though, technically, they are not bound by them, both bolstered this presumption. The Supreme Court of New Zealand, which was established by legislation in October 2003 and which replaced the Privy Council for future appeals, has continued to develop the presumption. Judgment was delivered on 3 March 2015 in the last appeal from New Zealand to be heard by the Privy Council.

The place of the Treaty of Waitangi in the constitution is the subject of much debate. The Treaty has no inherent legal status, but is treated in various statutes and is increasingly seen as an important source of constitutional law. The Treaty of Waitangi Act 1975 put the text of the Treaty in statute for the first time (as a schedule) and created the Waitangi Tribunal to investigate claims relating to the application of the principles of the Treaty. The Act was initially prospective but was amended in 1985 so that claims dating back to the signing of the Treaty in 1840 could be investigated. References to the "principles of the Treaty of Waitangi" appear in a number of statutes, although the principles themselves have not been defined in statute. They are instead defined by a common law decision of the Court of Appeal from 1987, the famous "Lands case" brought by the New Zealand Māori Council (New Zealand Maori Council v Attorney General) over concerns about the transfer of assets from former government departments to state owned enterprises, part of the restructuring of the New Zealand economy by the Fourth Labour Government. Because the state owned enterprises were essentially private firms owned by the government, they would prevent assets that had been given by Māori for use by the state from being returned to Māori by the Waitangi Tribunal. The Māori Council sought enforcement of section 9 of the State Owned Enterprises Act 1986: "Nothing in this act shall permit the Crown to act in a manner that is inconsistent with the principles of the Treaty of Waitangi."

The New Zealand Bill of Rights Act sets out the civil and political rights of New Zealand citizens against the three branches of government and entities and persons exercising public functions. The Act is not entrenched, and can, in theory, be amended by Parliament by a simple majority.

Prior to European settlement of New Zealand, Māori society was based largely around tribal units: iwi and hapū. As contact with Europeans increased, there arose a need for a single governing entity. In 1788, the colony of New South Wales was founded. According to Governor Arthur Phillip's amended Commission dated 25 April 1787, the colony included "all the islands adjacent in the Pacific Ocean" and running westward on the continent to the 135th meridian east. Until 1840, this technically included New Zealand, but the New South Wales administration had little interest in New Zealand. Amid increasing lawlessness and dubious land transactions between Māori and Europeans, the British Colonial Office appointed James Busby as British Resident to New Zealand. Busby convened the Confederation of Chiefs of the United Tribes of New Zealand, which adopted the Declaration of Independence of New Zealand at Waitangi in 1835. While the Declaration was acknowledged by King William IV, it did not provide a permanent solution to the issue of governance. In 1839 Letters Patent were created purported to extend the jurisdiction of the colony of New South Wales to New Zealand, in effect to annexe "any territory which is or may be acquired  within that group of Islands known as New Zealand". This strategy was adopted by the Colonial Office in order to allow time for Captain William Hobson to legally acquire sovereignty from the United Tribes of New Zealand by treaty. On 6 February 1840, the first copy of the Treaty of Waitangi (Te Tiriti o Waitangi) was signed at Waitangi. Several subsequent copies were signed at various places around the North and South Islands. On 21 May Hobson issued two proclamations of British sovereignty over New Zealand, one for the North Island by Treaty, and the other for the South Island by discovery (the South Island was declared "Terra nullius" or devoid of people.) A further declaration on 23 May decried the "illegal assumption of authority" by the New Zealand Company settlements in Port Nicholson (Wellington and Britannia, later Petone) establishing their own 12 member governing council. Hobson sought to prevent the establishment of what he saw as a 'republic', that is, an independent state outside of his jurisdiction. In August 1840, the Parliament of the United Kingdom passed the New Zealand Government Act of 1840, allowing the establishment of a colonial administration in New Zealand separated from New South Wales. Following this enactment, the Royal Charter of 1840 was declared. The Charter allowed for the establishment of the Legislative Council and Provincial Councils; Hobson was then declared Lieutenant Governor of New Zealand and divided the colony into two provinces (North Island—New Ulster, South Island—New Munster), named after the Northern and Southern Irish provinces. On 3 May 1841, New Zealand was established as a Crown colony in its own right, with Hobson declared governor.

The Imperial Conference of 1907 resolved to allow certain colonies to become independent states, termed 'Dominions'. Following the Conference, the House of Representatives passed a motion requesting that King Edward VII "take such steps as he may consider necessary; to change New Zealand's official name from 'The Colony of New Zealand' to 'The Dominion of New Zealand'. Prime Minister Sir Joseph Ward prompted to move to "raise up New Zealand" and assured that it would "have no other effect than that of doing the country good". On 9 September, a Royal Proclamation granting New Zealand Dominion status was issued by King Edward VII. The proclamation took effect on 27 September. As a result, the office of governor became governor general under the Letters Patent 1917 to reflect New Zealand's status as a dominion more fully. The Letters Patent also removed a number of powers the governor previously held while New Zealand was a colony. In 1908, two enactments of constitutional importance were passed: the Judicature Act, which describes the Jurisdiction of the New Zealand Judiciary; and the Legislature Act, setting out the powers of Parliament. The latter is now largely repealed, with only certain provisions that codify aspects of parliamentary privilege remaining. The Imperial Conference of 1926 affirmed the Balfour Declaration of 1926, which stated Britain's Dominions were "equal in status". In respect of the governor general, the Declaration stated that they held: "the same position in relation to the administration of public affairs in the Dominion" as was held by the monarch in the United Kingdom. The governor general was thus bound by the advice of their responsible ministers. To give effect to the 1926 conference declarations, the Statute of Westminster 1931 was passed thus lifting the restrictions created by the Colonial Laws Validity Act 1865. The Statute applied to New Zealand but would have to be adopted by the New Zealand Parliament as its own law to have application in New Zealand. After much debate, this occurred in 1947 with the Statute of Westminster Adoption Act. At the request of the New Zealand Parliament, Westminster passed the New Zealand Constitution (Amendment) Act 1947 to grant the New Zealand Parliament full sovereign powers to amend or repeal the New Zealand Constitution Act 1852. The Parliament of the United Kingdom could still pass laws at the request of the New Zealand Parliament. This residual power, which was used only for the 1947 Amendment Act, was abolished with the passing of the Constitution Act 1986, which repealed the 1852 Constitution Act. As a result of these changes, New Zealand became a "Realm", with a legally separate Crown. It was not until the 1983 Letters Patent, the first amendment of the Letters Patent since 1917, that New Zealand was described as the Realm of New Zealand, which includes the self governing territories of the Cook Islands and Niue.

The National Party won the promising to abolish the Legislative Council. The council was then stacked with the so nicknamed "suicide squad" to allow the passage of the Legislative Council Abolition Act 1950 by the House of Representatives to abolish the upper house. Despite proposals to re establish an upper house, such as Jim Bolger's Senate proposal in 1990, New Zealand's Parliament remains unicameral. As such, legislation is able to progress through the legislative stages much faster in comparison to other Westminster style parliament. Legal academic and politician Geoffrey Palmer described the New Zealand Parliament in 1979 as the "fastest law maker in the West".

Immediately following the in which the Labour Party gained a parliamentary majority, a constitutional crisis arose when incumbent Prime Minister Sir Robert Muldoon of the National Party refused to implement the instructions of Prime Minister elect David Lange to devalue the New Zealand dollar to head off a speculative run on the currency. The crisis was resolved when Muldoon relented three days later, under pressure from his own Cabinet, which threatened to install Deputy Prime Minister Jim McLay in his place. Following the constitutional crisis, the incoming Fourth Labour Government formed an Officials Committee on Constitutional Reform to review the transfer of power. As a result of the committee, the Government released the Bill of Rights White paper and also introduced the Constitution Act 1986, the first major review of the New Zealand Constitution Act for 134 years. Prior to this Act, only 12 of the 82 provisions of the 1852 Act remained in place. The Act consists of five main parts, covering the sovereign, the executive, the legislature, the judiciary, and miscellaneous provisions. Parliament also passed the Imperial Laws Application Act 1988 to clarify which Imperial and English Acts are to apply to New Zealand. The Fourth Labour government also began the process of electoral reform. It convened the Royal Commission on the Electoral System in 1986. The Commission suggested New Zealand change to the mixed member proportional (MMP) electoral system. Two referendums were held during the 1990s on the issue, with MMP being adopted in 1993 and implemented in 1996. Although MMP has resulted in many changes to New Zealand's political system, such as more complex governing arrangements negotiated between multiple parties, significant aspects of New Zealand's constitution remained the same following its adoption. For example, a proposal to create a supreme bill of rights that would grant courts the ability to invalidate Acts of Parliament via judicial review was rejected. Parliament still functions as the supreme lawmaker. The last major constitutional reform of the Fourth Labour Government was the New Zealand Bill of Rights Act 1990 (NZBORA). The NZBORA puts New Zealand's commitment to the 1977 International Covenant on Civil and Political Rights (ICCPR) into effect in New Zealand law. However, the Act is neither entrenched nor supreme law (as was mooted in the White Paper of 1985) and can, therefore, be repealed by a simple majority of Parliament.

A poll by TVNZ in 2004 found 82% of those surveyed thought New Zealand should have a "written constitution". In 2016, former Prime Minister Geoffrey Palmer and Andrew Butler created a "Constitution for Aotearoa New Zealand" to spark public discussion on a written constitution.

In December 2010, a Constitutional Review was announced as part of the confidence and supply agreement between the National Party and the Māori Party, starting in 2011. The agreement was part of the debate over the future of the Māori electorates. National had a policy of abolishing the seats while the Māori Party wanted the seats entrenched in law. The Constitutional Review was agreed as a way to satisfy both parties. An advisory panel supported ministers Bill English and Pita Sharples, who were to make a final report to Cabinet by the end of 2013. The ministers' first report to Cabinet agreed on the make up of the advisory panel, a plan for public engagement and how the review would interact with other government projects with a constitutional dimension, such as the referendum on MMP.

In 2010 the National Iwi Chairs Forum, a forum made up of people from iwi organisations across New Zealand set up a constitutional working group to create conversation with Māori how to develop a constitution for New Zealand from a Māori point of view. The Iwi Chairs' Forum directed the working party to frame the conversation based on He Whakaputanga (the 1835 Declaration of Independence), Te Tiriti o Waitangi, the United Nations Declaration on the Rights of Indigenous Peoples and principles of tikanga. Chaired by Margaret Mutu and convened by Moana Jackson, the working group held 252 meetings with Māori at marae and other settings between 2012 and 2015. The findings were launched in 2016 in a document called Matike Mai Aotearoa.
