 Many of the early Māori names were replaced by Europeans during the late 18th and early 19th centuries.Government amendments in 1894 and the establishment of the New Zealand Geographic Board in the mid-1940s led to the encouragement of original Māori names, although differing spellings and anglicised pronunciations persisted.Many names now have alternative or dual English and Māori names or, in a few rare cases, dual Māori names or dual English names.
