New Zealand was administered as part of the Colony of New South Wales until becoming a separate Crown colony, the Colony of New Zealand on 3 May 1841. Armed conflict began between the colonial government and Māori in 1843 with the Wairau Affray over land and disagreements over sovereignty. These conflicts, mainly in the North Island, saw thousands of imperial troops and the Royal Navy come to New Zealand and became known as the New Zealand Wars. Following these armed conflicts, large amounts of Māori land was confiscated by the government to meet settler demands.
