When is Chatham Islands Anniversary Day?
In 2026, Chatham Islands Anniversary Day falls on Monday, November 30, 2026. It is classified here as a New Zealand public holiday.
History of Chatham Islands Anniversary Day
Chatham Islands Anniversary Day is one of New Zealand's regional public holidays. Anniversary days preserve local identities associated with the former provincial system, although the provinces were abolished in 1876 and their old borders do not always match present councils. The date customarily observed can differ greatly from the nominal historical anniversary. It is not a second national holiday and should never be assigned automatically to workers outside the relevant locality.
The Chatham Islands observe the Monday nearest November 30. The islands are Rēkohu to Moriori and Wharekauri in Māori usage, and their history cannot be reduced to a former provincial date. Local identity includes Moriori settlement, later Māori arrivals, colonisation and enduring island communities far east of mainland New Zealand.
Employment New Zealand lists 30 November for Chatham Islands in 2026 but warns that anniversary information may contain errors and recommends checking the local council. Under the Holidays Act, payment and time off depend on whether that regional date would otherwise be a working day for the employee. Work attracts at least time-and-a-half and, where applicable, an alternative holiday; businesses and essential services are not required to close uniformly.
