The Holidays Act 1981 specifies each locality observing a Provincial Anniversary Day to celebrate the founding days or landing days of the first colonists of the various colonial provinces.
However the exact dates are not legislated for.
The regions covered are set by provincial district (as they stood when abolished in 1876), plus Southland, the Chatham Islands, South Canterbury and Northland.
The actual observance days can vary even within each province and is due to local custom, convenience or the proximity of seasonal events or other holidays.
This may differ from the official observance day, and may be several weeks from the official day.
The Northern and Central Canterbury regions take Christchurch Show Day as their provincial holiday. The Canterbury Show Day celebration is the second Friday after the first Tuesday in November
The provincial holiday is celebrated on the Monday nearest to 30 November.
Hawke's Bay Anniversary Day is held on the Friday before Labour Day. Hawke's Bay province was created when it was split from Wellington on 1 November 1958. It became a provincial district in 1876. Hawke's Bay was named by Captain Cook in honour of Edward Hawke, First Lord of the Admiralty.
The provincial day in South Canterbury is Dominion Day, which is celebrated on the fourth Monday in September. Dominion Day commemorates 26 September 1907, when New Zealand was granted Dominion status within the British Empire.
