Herd surveyed parts of the harbour at Hokianga, where either he or the company's agent on board negotiated the "purchase" of tracts of land from Māori in Hokianga, Manukau and Paeroa. The price for the land was "five muskets, fifty three pounds powder, four pair blankets, three hundred flints and four musket cartridge boxes". After several weeks Herd and the New Zealand Company agent decided the cost of exporting goods was too high to be of economic value and they sailed to Sydney, where Herd paid off the crew and sold the stores and equipment, then returned to London. The venture had cost the New Zealand Company £20,000. Wakefield's influence The failure of Lambton's project came to the attention of 30-year-old aspiring politician Edward Gibbon Wakefield, who was serving three years in jail for abducting a 15-year-old heiress. Wakefield, who had grown up in a family with roots in philanthropy and social reform, also showed an interest in proposals by Robert Wilmot-Horton, Under-Secretary of State for War and the Colonies for state-assisted emigration programmes that would help British paupers escape poverty by moving to any of Britain's colonies. In 1829 Wakefield began publishing pamphlets and writing newspaper articles that were reprinted in a book, promoting the concept of systematic emigration to Australasia through a commercial profit-making enterprise. Wakefield's plan entailed a company buying land from the indigenous residents of Australia or New Zealand very cheaply, then selling it to speculators and "gentleman settlers" for a much higher sum. The immigrants would provide the labour to break in the gentlemen's lands and cater to their employers' everyday needs. They would eventually be able to buy their own land, but high land prices and low rates of pay would ensure they first laboured for many years. In May 1830 Wakefield was released from prison and joined the National Colonisation Society, whose committee included Wilmot-Horton, nine MPs and three clergymen. Wakefield's influence within the society quickly grew and by the end of the year his plans for colonisation of Australasia had become the central focus of the society's pamphlets and lectures. Despite the £20,000 loss incurred in his earlier venture, Lambton (from the 1830s known as Lord Durham) continued to pursue ways to become involved in commercial emigration schemes and was joined in his endeavours by Radical MPs Charles Buller and Sir William Molesworth. In 1831 and again in 1833 Buller and Molesworth
