The Hutt Valley campaign was an armed conflict in the lower North Island of New Zealand between indigenous Māori and British settlers and military forces in 1846. The campaign was among the earliest of the 19th century New Zealand Wars that were fought over issues of land and sovereignty. It was preceded by the Wairau affray (June 1843) and followed by the Wanganui campaign (April–July 1847) and was triggered by much the same pressures—the careless land purchasing practices of the New Zealand Company, armed government support for settler land claims, and complex intertribal tensions between local Māori. The three conflicts also shared many of the same combatants.
