Title: New Zealand Government
Content:  The New Zealand Government (Te Kāwanatanga o Aotearoa), formally termed Her Majesty's Government, is the central government through which governing authority is exercised in New Zealand. As in most 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 Queen 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. Executive power is exercised by ministers, all of whom are sworn into the Executive Council and accountable to the elected legislature, the House of Representatives. Several senior ministers (usually 20) constitute a collective decision-making body 
Title: Politics of New Zealand
Content:   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. 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. 
Title: Politics of New Zealand
Content:  power in New Zealand is based on the principle that "The Queen reigns, but the government rules". 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. The country ranks highly for government transparency, and has the lowest perceived level of corruption in the world.

Queen Elizabeth II is the country's monarch and is represented by the governor-general. In addition, New Zealand is organised into 11 regional councils and 67 territorial authorities for local government purposes. The Realm of New Zealand also includes Tokelau (a dependent territory); the Cook Islands and Niue (self-governing states in free association with New Zealand); and the Ross Dependency, which is New Zealand's territorial claim in Antarctica. New Zealand is a member of the United Nations, Commonwealth of Nations, ANZUS, OECD, ASEAN Plus Six, Asia-Pacific Economic Cooperation, the Pacific Community and the Pacific Islands Forum.
Title: New Zealand Government
Content:   In New Zealand, the term Government can have a number of different meanings. At its widest, it can refer collectively to the three traditional branches of government—namely, the executive branch, legislative branch (the Queen-in-Parliament and House of Representatives) and judicial branch (the Supreme Court and subordinate courts). Each branch operates independently of the others in an arrangement described as "separation of powers". More commonly, the term is used to refer specifically to the executive branch. The largest party or coalition in the House of Representatives, with a sufficient number of MPs to win crucial parliamentary votes, will form a Cabinet—this is the sense intended when it is said that a political party "forms the government". The Constitution Act 1986, the principal part of New Zealand's constitution, locates the executive government in the Executive Council, which also includes ministers outside Cabinet. The Executive Wing of Parliament Buildings, commonly called the "Beehive" because of the building's shape, houses many government offices and is also where the Cabinet meets. Thus the name Beehive is sometimes used metonymically to refer to the New Zealand Government. The official website of the New Zealand Government uses the web address.

The New Zealand Parliament holds legislative power and consists of the Queen and the House of Representatives.

Title: New Zealand Government
Content:  The New Zealand Government is formally termed Her Majesty's Government on the Seal of New Zealand. This is a reference to the monarch, currently Queen Elizabeth II, who is identified as the head of state in the Constitution Act 1986. The legal authority of the state that is vested in the monarch, known as "the Crown", remains the source of the executive power exercised by the Government. Sovereignty in New Zealand has never rested solely with the monarch due to the English Bill of Rights 1689, later inherited by New Zealand, which establishes the principle of parliamentary sovereignty. Nonetheless, the Constitution Act describes the monarch as the "Sovereign". In many areas the Crown possesses a body of powers known as the royal prerogative. For example,

Content:  New Zealand is a constitutional monarchy with a parliamentary democracy, although its constitution is not codified. Elizabeth II is the queen of New Zealand and thus the head of state. The queen is represented by the governor-general, whom she appoints on the advice of the prime minister. The governor-general can exercise the Crown's prerogative powers, such as reviewing cases of injustice and making appointments of ministers, ambassadors, and other key public officials, and in rare situations, the reserve powers (e.g. the power to dissolve parliament or refuse the royal assent of a bill into law). The powers of the monarch and the governor-general are limited by constitutional constraints, and they 
Title: Constitution of New Zealand
Content:  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).
