Judicial review in New Zealand

Judicial review, under which executive actions of the Government are subject to review, and possible invalidation, is used in New Zealand. Judicial review is carried out by a judge of the High Court of New Zealand. Legislative action is not justiciable in the High Court under New Zealand's Westminster constitutional arrangements; Parliament remains supreme in law.

The Judicature Act 1908 and its amendments, especially the Judicature Amendment Act 1972, govern the process of judicial review.
