The Dominion of New Zealand is the historic predecessor to the Realm of New Zealand. Originally administered from New South Wales, New Zealand became a separate British Crown colony in 1841 and received a large measure of self-government following the New Zealand Constitution Act 1852. New Zealand chose not to take part in Australian Federation and assumed complete self-government as the Dominion of New Zealand on 26 September 1907, Dominion Day, by proclamation of King Edward VII.
