Ngāi Tahu use of the land was ended by attacks by North Island tribes. In 1836, the Ngati Tama chief Te Puoho led a 100-person war party, armed with muskets, down the West Coast and over the Haast Pass: they fell on the Ngāi Tahu encampment between Lake Wānaka and Lake Hāwea, capturing 10 people and killing and eating two children. Although Te Puoho was later killed by the southern Ngāi Tahu leader Tuhawaiki, Māori seasonal visits to the area ceased.
