The Supreme Court of New Zealand is the highest court and the court of last resort of New Zealand. It formally came into being on 1 January 2004 and sat for the first time on 1 July 2004. It replaced the right of appeal to the Judicial Committee of the Privy Council, based in London. It was created with the passing of the Supreme Court Act 2003, on 15 October 2003. At the time, the creation of the Supreme Court and the abolition of appeals to the Privy Council were controversial constitutional changes in New Zealand. The Supreme Court Act 2003 was repealed on 1 March 2017 and superseded by the Senior Courts Act 2016.

The Fifth Labour Government of New Zealand was the government of New Zealand from 10 December 1999 to 19 November 2008. Labour Party leader Helen Clark negotiated a coalition with Jim Anderton, leader of the Alliance Party. While undertaking a number of substantial reforms, it was not particularly radical compared to previous Labour governments.
