The 2nd New Zealand Parliament was a term of the Parliament of New Zealand. It opened on 15 April 1856, following New Zealand's 1855 election. It was dissolved on 5 November 1860 in preparation for 1860–61 election. The 2nd Parliament was the first under which New Zealand had responsible government, meaning that unlike previously, the Cabinet was chosen (although not officially appointed) by Parliament rather than by the Governor. Historical context At this time political parties had not been established (they were not established until after the 1890 election), meaning that anyone attempting to form an administration had to win support directly from individual MPs. This made forming (and retaining) a government difficult. The Sewell Ministry, the first responsible government, led by Henry Sewell, lasted only two weeks. The first Fox Ministry, the second responsible government, led by William Fox, also lasted only two weeks. The third responsible government, the first Stafford Ministry, led by Edward Stafford, was more stable, governing for the remainder of the 2nd Parliament and for the beginning of the 3rd.

The 1858 Amendment changed the boundaries to: Initial composition of the 2nd Parliament Changes during term The turnover of MPs was very high in the 2nd Parliament, with 32 by-elections and a supplementary election being held. This situation was partly the result of a redistribution of boundaries to seven electorates, and the creation of four new electorates – agreed upon in the Electoral Districts Act, 1858, with the total number of MPs in Parliament rising from 37 to 41, and the number of electorates rising from 24 to 28. The northern portion of the Northern Division electorate was split off and became the electorate of Marsden. The Wairarapa and Hawke's Bay electorate was split into two separate components, and . All the previously unincorporated areas in the lower North Island were divided between Wairarapa, County of Hawke, , and . In the South Island, the southern portion of Wairau electorate, plus part of Christchurch Country, became the new Cheviot
