Prime Minister of New Zealand

The prime minister of New Zealand is the head of government of New Zealand. The prime minister, Jacinda Ardern, leader of the New Zealand Labour Party, took office on 26 October 2017.
The prime minister ranks as the most senior government minister. They are responsible for chairing meetings of Cabinet; allocating posts to ministers within the government; acting as the spokesperson for the government; and providing advice to the sovereign or the sovereign's representative, the governor-general. They also have ministerial responsibility for the Department of the Prime Minister and Cabinet.
The office exists by a long-established convention, which originated in New Zealand's former colonial power, the then United Kingdom of Great Britain and Ireland. The convention stipulates that the governor-general must select as prime minister the person most likely to command the support, or confidence, of the House of Representatives. This individual is typically the parliamentary leader of the political party that holds the largest number of seats in that chamber. The prime minister and Cabinet are collectively accountable for their actions to the governor-general, to the House of Representatives, to their political party, and ultimately to the national electorate.
Originally the head of government was titled "colonial secretary" or "first minister". This was changed in 1869 to "premier". That title remained in use for more than 30 years, until Richard Seddon informally changed it to "prime minister" in 1901 during his tenure in the office. Following the declaration of New Zealand as a Dominion in 1907, the title of Prime Minister has been used exclusively in English. In Māori, the title pirimia, meaning "premier", continues to be used. New Zealand prime ministers are styled as "The Right Honourable", a privilege they retain for life.

Appointment and tenure

The governor-general appoints a prime minister, like other ministerial positions, on behalf of the monarch. By the conventions of responsible government, the governor-general will call to form a government the individual most likely to receive the support, or confidence, of a majority of the elected members of Parliament. In making this appointment, convention requires the governor-general to act on the outcome of the electoral process and subsequent discussions between political parties by which the person who will lead the government as prime minister is identified. In practice, the position generally falls to the parliamentary leader of the largest political party among those forming the government. The prime minister may lead a coalition government and/or a minority government dependent on support from smaller parties during confidence-and-supply votes.
Once appointed and sworn in by the governor-general, the prime minister remains in the post until dismissal, resignation, or death in office. The prime minister, like other ministers, holds office "during the pleasure of the Governor-General", so theoretically, the governor-general can dismiss a prime minister at any time; however, convention heavily circumscribes the power to do so. The governor-general might rarely exercise reserve power to dismiss a prime minister in circumstances pertaining to a non-confidence motion against the government in Parliament.

Responsibilities and powers

The office is not defined by codified laws, but by unwritten customs known as constitutional conventions which developed in Britain and were replicated in New Zealand. These conventions are for the most part founded on the underlying principle that the prime minister and fellow ministers must not lose the confidence of the democratically elected component of parliament, the House of Representatives. The prime minister is leader of the Cabinet, and takes a coordinating role.
The Cabinet Manual provides an outline of the prime minister's powers and responsibilities.

Principal adviser to the sovereign

By constitutional convention, the prime minister holds formal power to advise the sovereign. This means that as long as the prime minister has the confidence of parliament, they alone may advise the monarch on:
As head of government, the prime minister alone has the right to advise the governor-general to:
The prime minister is regarded by convention as "first among equals". They do hold the most senior post in government, but are also required to adhere to any decisions taken by Cabinet, as per the convention of collective ministerial responsibility. The actual ability of a prime minister to give direct orders is largely limited; most of the position's power comes about through other means, such as:
Since the introduction of the MMP electoral system, there has been an increased need for the prime minister to be able to negotiate and maintain relationships with support parties, which places some constraints on their abilities.

Other roles and functions

The prime minister is also expected to take on additional portfolios. Historically, the prime minister looked after colonial and revenue portfolios. As New Zealand expanded, the role of minister of finance became too big; Prime Minister Sir Robert Muldoon was criticised for taking on the finance portfolio during his time in office as it resulted in a large concentration of power in one individual.
Before 1987, it was also common for prime ministers to take the role of minister of foreign affairs, so they could represent New Zealand on an international stage. More recent prime ministers have taken portfolios relevant to their interests, or to promote specific areas they saw as important. For example, David Lange took the education portfolio in his second term; Helen Clark took the role of Minister for Arts, Culture and Heritage; John Key was Minister for Tourism; and Jacinda Ardern is Minister for Child Poverty Reduction.
Although no longer likely to be the minister of foreign affairs, the prime minister is still responsible for welcoming foreign heads of government, visiting leaders overseas, and attending Commonwealth Heads of Government Meetings.
Conventionally, the prime minister is the responsible minister for the Department of the Prime Minister and Cabinet, which is tasked with supporting the policy agenda of Cabinet through policy advice and the coordination of the implementation of key government programmes. Under the Fifth National Government the DPMC expanded to give prime ministers greater supervision of security and intelligence. The prime minister was also responsible for the New Zealand Security and Intelligence Service and the Government Communications Security Bureau.

Salary and perquisites

Under the Remuneration Authority Act 1977, and the members of Parliament Act 2013, a prime minister's salary is determined annually by the Remuneration Authority, an independent body established by parliament to set salaries for members of parliament and other government officials. For the fiscal year from 1 July 2017 to 30 June 2018, the prime minister's salary is NZ$471,049, plus a tax-free allowance of NZ$22,606 to cover out-of-pocket official expenses such as meals, gifts, and entertainment. In addition, like all other ministers and members of parliament, the prime minister receives annual allowances for travel and lodging, as do the prime minister's spouse and children.
The incumbent prime minister's official residence is Premier House, Tinakori Road, Wellington. Unlike the residences of certain other heads of government, Premier House does not serve as the government headquarters; instead the Beehive is the location of the prime minister's office. The prime minister's governmental work is supported by the non-partisan Department of the Prime Minister and Cabinet. The separate Private Office of the Prime Minister provides advice and support on political party matters.
The style of "The Right Honourable" is always granted to the prime minister upon taking office. Former prime ministers retain this style for the remainder of their lives. The written form of address for the head of government should use their full parliamentary title as applicable: The Right Honourable , , Prime Minister of New Zealand. It is also traditional for the monarch to bestow a knighthood on prime ministers after they leave office, and two prime ministers were knighted while still in office.
Should a serving or former prime minister die, she or he is accorded a state funeral. Two prime ministers who died in office were buried in mausoleums: William Massey in the Massey Memorial in Wellington, and Michael Joseph Savage in the Savage Memorial at Bastion Point in Auckland.


The Diplomatic Protection Service is a special branch of the New Zealand Police that is charged with protecting the prime minister and other senior government officials, as well as diplomats.


Assuming that Henry Sewell is counted as the first prime minister, 40 individuals have held the office since it was established. Some of these people have held it on several different occasions, with the record for maximum number of times being shared between William Fox and Harry Atkinson. The longest that anyone has served in the office is 13 years, a record set by Richard Seddon. The first holder of the office, Henry Sewell, led the country for the shortest total time; his only term lasted just 13 days. The shortest term belonged to Harry Atkinson, whose third term lasted only seven days, but Atkinson served longer in total than did Sewell. The youngest was Edward Stafford, who was appointed premier in 1856, at 37 years, 40 days old. The oldest was Walter Nash, who was 78 years old when he left office in 1960.
New Zealand is one of the few countries in the world to have had three female heads of government, and one of only three countries to have had a female head of government directly succeed another. The first female prime minister was Jenny Shipley of the National Party, who replaced Jim Bolger in late 1997; Shipley was succeeded by Helen Clark in 1999. Jacinda Ardern, the second female leader of the Labour Party after Clark, became prime minister in 2017.

Early leaders

On becoming the Colony of New Zealand in 1841, New Zealand was directly governed by a governor, appointed by the Colonial Office in Britain. Self-government was established in 1853, following the New Zealand Constitution Act 1852, and the First Parliament met on 24 May 1854.
The origins of the office of prime minister are disputed. Use of the words "prime minister" as a descriptive term date back to the First Parliament, where they are applied to James FitzGerald and Thomas Forsaith. FitzGerald and Forsaith had no official titles, however, and New Zealand had not yet obtained self-government. As such, they are not usually considered prime ministers in any substantive sense.
The first person to be formally appointed to a position of executive leadership was Henry Sewell, who formed a brief ministry in April 1856, at the beginning of the Second Parliament. Despite his formal leadership role, however, his only actual title was "colonial secretary", a position comparable to a minister of internal affairs. His successor, William Fox, was also given a formal leadership role, but was not colonial secretary. When Frederick Weld became the sixth person appointed to formal leadership, a substantive leadership title, "premier", appeared. Weld's successor, Edward Stafford, briefly changed the title to "first minister", but it was soon restored to premier during the second tenure of Fox. From that point, the term "premier" was used almost exclusively for the remainder of the 19th century. Nevertheless, in the Schedule of the Civil List of 1873, provision was made for the salary of the head of government, referred to as the "Prime Minister".
Initially, premiers acted as mere advisers to the governor—with the governor at times a very active partner. This began to change during the first tenure of Edward Stafford. Stafford met with his ministers and made decisions outside of the Executive Council, thus establishing the modern convention of cabinet government. Stafford also clashed with the governor over control of native affairs, which was eventually to fall within the premier's powers.

Party leadership

The political position of the premier was enhanced by the development of modern political parties; premier John Ballance organised the first formal party in New Zealand, forming the Liberal Government in 1891.. Although not every government would have a large majority, the party system and tight control of party members by whips helped heads of government to direct the passage of legislation in the House of Representatives. In 1893, the premier gained the ability to restrict the term of appointments to the Legislative Council.
The title of "prime minister" was used by Richard Seddon after 1901, following New Zealand's self-exclusion from the Federation of Australia. Seddon's immediate successor, William Hall-Jones, was the first to be sworn-in as "prime minister", in 1906.
The expanding power of the prime minister was kept in check by the need to build consensus with other leading members of Cabinet and of the governing party, including those who represented various ideological wings of the party. Other institutions, including Parliament itself and the wider state bureaucracy, also acted as limits on prime ministerial power; in 1912 Thomas Mackenzie was the last prime minister to lose power through an unsuccessful confidence motion in the House of Representatives.

Towards modern leadership

One change brought about by the First World War was direct participation in governing the British Empire. Previously, New Zealand prime ministers had attended occasional colonial and imperial conferences, but they otherwise communicated with London through the governor. In 1917, however, British prime minister David Lloyd George offered the New Zealand prime minister a seat in the Imperial War Cabinet, the British Empire's wartime coordinating body. In 1919, Bill Massey signed the Treaty of Versailles on behalf of New Zealand, signalling both prestige within the empire as well as a new independence for the country.
Constitutional conventions adopted in 1930, following the Imperial Conference held that year, increased the domestic and international prestige of the prime minister. The Statute of Westminster 1931 confirmed that Dominions had exclusive power to make their laws. New Zealand initially resisted greater autonomy and did not adopt the statute until 1947. Increasingly, however, New Zealand began to act independently in foreign affairs. During the 1940s the prime minister's profile rose as New Zealand signed a number of international treaties. In 1967, Keith Holyoake became the first New Zealand prime minister to select candidates for the position of governor-general without any involvement of the British government. Holyoake advised the monarch, Queen Elizabeth II, to appoint Sir Arthur Porritt, the first New Zealand-born governor-general.

After the mixed-member proportional system was introduced in 1996, prime ministers have had to manage minority governments. The skill of MMP management was exemplified by Helen Clark's nine years as prime minister, when her Labour government remained in power thanks to a range of confidence-and-supply agreements with five smaller parties.
Until the premiership of Helen Clark, it was customary for senior members of the legislature, executive and judiciary—including the prime minister—to be appointed to the British Privy Council, granting them the style "Right Honourable". This practice was discontinued at the same time as the abolition of knighthoods and damehoods in 2000 from the New Zealand honours system. National's John Key became prime minister in 2008 and moved to restore titular honours, but did not resume appointments to the Privy Council, meaning Key was styled "The Honourable". However, on 3 August 2010 the Queen granted the prime minister, along with the governor-general, speaker of the House of Representatives and chief justice, the style "Right Honourable" upon appointment.
On 21 June 2018, Labour's Jacinda Ardern became the first prime minister of New Zealand to give birth while in office.

Living former prime ministers

As of, there are six living former New Zealand prime ministers, as seen below.
The most recent prime minister to die was Mike Moore, on 2 February 2020, aged 71.

Deputy Prime Minister

A position officially titled deputy prime minister has existed since 1954. The deputy typically holds important ministerial portfolios and, by convention, becomes acting prime minister in the absence or incapacity of the prime minister. The deputy is commonly a member of the same party as the prime minister, but not necessarily so; in coalition governments the parliamentary leader of a junior party may be offered the post. Winston Peters, leader of New Zealand First, is the current deputy prime minister, also serving as Minister of Foreign Affairs.
