Responsibility for the beginning of the musket wars is usually attributed to Ngāpuhi chief Hongi Hika, who in 1818 used newly acquired muskets to launch devastating raids from his Northland base into the Bay of Plenty, where local Māori were still relying on traditional weapons of wood and stone. In the following years he launched equally successful raids on iwi in Auckland, Thames, Waikato and Lake Rotorua,[1] taking large numbers of his enemies as slaves, who were put to work cultivating and dressing flax to trade with Europeans for more muskets. His success prompted other iwi to procure firearms in order to mount effective methods of defence and deterrence and the spiral of violence peaked in 1832 and 1833, by which time it had spread to all parts of the country except the inland area of the North Island later known as the King Country and remote bays and valleys of Fiordland in the South Island.
