The Constitution Act in 1852 established the system of government and these were later consolidated in 1986. Constitutional rights are protected under common law and are strengthened by the Bill of Rights Act 1990 and Human Rights Act 1993, although these are not entrenched and can be overturned by Parliament with a simple majority. The Constitution Act describes the three branches of Government in New Zealand: The Executive (the Sovereign and Cabinet), the legislature (Parliament) and the judiciary (Courts).
