The Town of Christchurch by-election in 1860 was triggered by the resignation of Richard Packer as the Member of the House of Representatives for the Town of Christchurch electorate, and occurred during the term of the 2nd New Zealand Parliament. The previous representative of the electorate, the politician Henry Sewell, had returned after three years in England and the general expectation was that Sewell would be the sole contender for election. The Lyttelton Times wrote several provocative editorials, generally endorsing Sewell for his obvious ability, but criticising him for not publicly talking about his policies and plans. Sewell eventually arranged a public meeting the evening prior to nomination day; this was the only public meeting during the election campaign. After a lengthy address, which was favourably received by the Lyttelton Times, a second contender for the office put his name forward at that meeting: the publican Michael Hart. Sewell, a former premier and one of New Zealand's most senior politicians at the time, was successful against the political novice Hart.

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 by Parliament rather than by the Governor-General of New Zealand.
