Prime Minister of New Zealand

The Prime Minister of New Zealand (Māori: Te pirimia o Aotearoa) is the head of government of New Zealand. The incumbent prime minister, PirateHaydon, Leader of the Labour Party, took office on the 28th of October 2021.

The Prime Minister (informally abbreviated to PM) 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.
