Politics of New Zealand

The politics of New Zealand function within a framework of a unitary parliamentary representative democracy. The structure 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 Queen Elizabeth II is the sovereign and head of state.

Organisational chart of the New Zealand political system

The New Zealand Parliament holds legislative power and consists of the Queen and the House of Representatives. The Queen is represented by the Governor-General of New Zealand when not present in the country herself. Members of Parliament (MPs) are elected to the House of Representatives usually every three years. The country has a multi-party system, though the dominant political parties in New Zealand have historically been the Labour Party and the National Party (or its predecessors). Minority governments are common and typically dependent on confidence-and-supply agreements with other parties.

Executive power in New Zealand is based on the principle that "The Queen reigns, but the government rules".[1] Although an integral part of the process of government, the Queen and her governor-general remain politically neutral and are not involved in the everyday aspects of governing. Ministers are selected from among the democratically elected members of the House of Representatives. Most ministers are members of the Cabinet, which is the main decision-making body of the New Zealand Government. The prime minister is the most senior minister, chair of the Cabinet, and thus head of government. Other ministers are appointed by the governor-general upon the advice of the prime minister, and are all accountable to Parliament.

The Economist Intelligence Unit rated New Zealand as a "full democracy" in 2016.[2] The country ranks highly for government transparency, and has the lowest perceived level of corruption in the world.[3]
