1856 Sewell Ministry
From 7 May onwards, Henry Sewell held office as colonial secretary, considered to be the equivalent of a prime minister or premier.Sir George Grey, the 3rd Governor of New Zealand, greatly influenced the New Zealand Constitution Act 1852 (UK), which granted the colony self-government, allowing for a bicameral Parliament consisting of an elected House of Representatives of 24 to 42 members, and an appointed Legislative Council of not fewer than ten members.It also allowed for provinces to be formed, each presided over by an elected Superintendent, for initially Auckland, Taranaki, Wellington, Nelson, Canterbury and Otago.[1] Once the provincial governments had been set up, New Zealand had given itself six miniature parliaments, endeavouring to emulate Westminster as best they could, for a total European population of about 30,000.He was appointed to the Executive Council on 18 April 1856, and became Colonial Secretary (considered to be the equivalent of Prime Minister), at the head of New Zealand's first responsible government, on 7 May.
