The New Zealand Oath of Allegiance is defined by the Oaths and Declarations Act 1957. The Oath is required under New Zealand law to be made in certain circumstances, including as a requirement for individuals to hold certain offices, as well in judicial proceedings.
Since 2002, all Oaths can be taken in either Māori or English form. It is possible to take an affirmation, which has the same legal effect as an Oath.
