The Crimes Act 1961 is an act of New Zealand Parliament that forms a leading part of the criminal law in New Zealand. It repeals the Crimes Act 1908, itself a successor of the Criminal Code Act 1893. Most crimes in New Zealand are created by the Crimes Act, but some are created elsewhere. All common law offences are abolished by section 9, as are all offences against acts of the British Parliaments, but section 20 saves the old common law defences where they are not specifically altered.
