Kaipara and Hokianga. The company provided Wakefield with a lengthy list of instructions to be carried out on his arrival. He was told to seek land for settlements where there were safe harbours that would foster export trade, rivers allowing passage to fertile inland property, and waterfalls that could power industry. He was told the company was eager to acquire land around harbours on both sides of Cook Strait and that while Port Nicholson appeared the best site he should also closely examine Queen Charlotte Sound and Cloudy Bay at the north of the South Island. He was told to explain to Māori that the company wanted to buy land for resale to allow large-scale European settlement and that he should emphasise to tribes that in every land sale, one-tenth would be reserved for Māori, who would then live where they were assigned by a lottery draw in London. Wakefield was told: Wakefield arrived at Cook Strait on 16 August and spent several weeks exploring the bays and sounds at the north of the South Island. The Tory crossed Cook Strait on 20 September and with the aid of whaler and trader Dicky Barrett—who had lived among Māori in Taranaki and the Wellington area since 1828 and also spoke "pidgin-Māori"—Wakefield began to offer guns, utensils and clothing to buy land from the Māori around Petone. Within a week he had secured the entire harbour and all surrounding ranges, and from then until November went on to secure signatures and marks on parchments that supposedly gave the company ownership of 20 million acres (8 million hectares)—about one-third of New Zealand's land surface at a cost of about a halfpenny an acre. On 25 October he persuaded 10 chiefs at Kapiti to add crosses at the foot of an 1180-word document that confirmed they were permanently parting with all "rights, claims, titles and interests" to vast areas of land in both the South and North Islands as far north as present-day New Plymouth. On 8 November in Queen Charlotte Sound he secured the signature of an exiled Taranaki chief, Wiremu Kīngi, and 31 others for land whose description was near-identical to that of the Kapiti deal. On 16 November as the Tory passed Wanganui three chiefs came aboard the Tory to negotiate the sale of all their district from Manawatu to Patea. The areas in each deed were so vast Wakefield documented
