The Colony of New Zealand is a British colony that exists in New Zealand from 1841 to 1907, created as a Crown colony. The power of the British Government is vested in a governor, but the colony is granted self-government in 1852. The 1852 Constitution is inaugurated after the first parliament is elected in 1853, and the first government of New Zealand is formed in 1856.

The Colony of New Zealand had three capitals: Old Russell (1841), Auckland (1841–1865), and Wellington (after 1865). In 1907, the colony becaomes the Dominion of New Zealand with a more explicit recognition of self-government within the British Empire.
