The Colony of New Zealand was a colony of the United Kingdom from 1841 to 1907. British authority was vested in a governor. The colony had three successive capitals: Okiato in 1841; Auckland from 1841 to 1865; and Wellington from 1865. Following the New Zealand Constitution Act 1852, the colony became a Crown colony with its first elected parliament in 1853. Responsible self-government was established in 1856 with the governor being required to act on the advice of his ministers. In 1907, the colony became the Dominion of New Zealand.
