The Arahura Deed was a land sale and agreement between KÃÂi Tahu iwi and James Mackay on behalf of the New Zealand settler government, signed on 21 May 1860 by Poutini chiefs at MÃÂwhera (modern-day Greymouth).
The signed document provided for the chiefs to give up their people's customary title on of whenua (land) in return for ã300 (about 1d per 100 acres) with 6,724 acres reserved for the people of the iwi, another 3,500 for "religious, social and moral purposes", 2,000 acres for later sale to cover surveying costs and 472 acres allocated to NgÃÂti Apa. It also allowed KÃÂi Tahu to buy back land between the river and Tà «hua mountain at 10s. per acre (12,000 times as expensive as the acres sold to the government). In 1991 the Waitangi Tribunal found that, "In offering to pay no more than a nominal price for land which had the potential for a very early substantial rise in value, the tribunal concluded that the Crown failed to act with the degree of good faith required of one Treaty partner to the other."
