By Wakefield it was that the Colonial Office was forced to annex New Zealand. In the face of the causes making for annexation sketched in the last chapter, the officials hung back to the last. In 1837 a body of persons appeared on the scene, and opened siege before Downing Street, whom even permanent officials could not ignore. They were composed of men of good standing, in some cases of rank and even personal distinction. They were not traders, but colonizers, and as such could not be ignored, for their objects were legitimate and their hands as clean as those of the missionaries. They first formed, in 1837, a body called “The New Zealand Association.” At their head was Mr. Francis Baring. Their more prominent members included John Lambton Earl of Durham, Lord Petre, Mr. Charles Enderby, Mr. William Hutt, Mr. Campbell of Islay, Mr. Ferguson of Raith, Sir George Sinclair, and Sir William Molesworth. The Earl of Durham was an aristocratic Radical of irregular temper, who played a great part in another colonial theatre—Canada. Sir William Molesworth did much to aid the agitation which put an end to the transportation of convicts to Australia. For the rest, the Association thought the thoughts, spoke the words, and made the moves of Gibbon Wakefield. Yet though he pervaded it sleeplessly, its life was but an episode in his career. He fought against the convict system with Molesworth and Rentoul of the Spectator. He went to Canada as Lord Durham’s secretary and adviser. He was actively concerned in the foundation of South Australia, where his system of high prices for land helped to bring about one of the maddest little land “booms” in colonial history. And as these things were not enough to occupy that daring, original, and indefatigable spirit, he threw himself into the colonization of New Zealand. He and his brother, Colonel Wakefield, became the brain and hand of the New Zealand colonizers.
