Wanaka was visited annually by Ngāi Tahu who sought greenstone in the mountains above the Haast River and hunted eels and birds over summer, returning to the east coast by descending the Clutha River / Mata-Au in reed boats called mōkihi. Ngāi Tahu use of the land was ended by attacks by North Island tribes. In 1836, the Ngāti 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. Some of the Ngāi Tahu fled down the Waitaki river to the coast; Te Puoho took his captives over the Crown Range to Lake Wakatipu and thence to Southland where he was killed and his war party destroyed by the southern Ngāi Tahu leader Tuhawaiki.
