Constitution of New Zealand
There is no entrenched law that forms the New Zealand constitution. The Constitution Act 1986 and a collection of statutes (Acts of Parliament), the Treaty of Waitangi, Orders in Council, letters patent, decisions of the Courts and unwritten constitutional conventions, comprises only a portion of the uncodified constitution of New Zealand.New Zealand is a constitutional monarchy with a parliamentary system of government. This system is based on the Westminster system, although that term is increasingly inapt given constitutional developments peculiar to New Zealand. The head of state, the monarch of New Zealand is represented in the Realm of New Zealand by the Governor-General and is the source of executive, judicial and legislative power.
