Conservatism in New Zealand is related to its counterparts in other Western nations, but developed uniquely over time. Advocates followed a political ideology that argued against progressivism and emphasised the preservation of traditional beliefs and practices.
Initially conservatism was a philosophy used by the "men in possession" of a new country, but most of all it espoused the spirits of individualism akin to Herbert Spencer's theories. Prior to the mid-1870s, New Zealand's political factions were based less on ideologies and more on provincial allegiances. This was to change however, with members of parliament becoming more identifiable as one of two groups—"Conservative" or "Liberal"—akin to Britain. The labels often walked hand in hand with each MP's stance on land policy. Nearly all those calling themselves conservatives supported freehold policy, while those labelled as liberals advocated for leasehold legislature.
From 1876 to 1890 the conservative factions dominated the House of Representatives. The so-called "Continuous Ministry" governed almost this whole period, with two breaks from October 1877 to October 1879 and August 1884 to October 1887, when "Liberal" ministries were formed under George Grey and Robert Stout, respectively. The Continuous Ministry was governing once again in 1887–88, the worst years of the Long Depression, when Premier Harry Atkinson became very unpopular, even with the wealthy his erstwhile supporters. The ensuing election in 1890 was a disaster. An ailing Atkinson resigned and a new ministry was formed under John Ballance and his recently formed Liberal Party.
The beginning of party politics in New Zealand was a setback for conservative-oriented politicians, worsened by the accession of the immensely popular Richard Seddon to the premiership. His opponents struggled to set up an equivalent full-scale organisation in competition to the Liberal Party. Conservative politicians operated under various banners in this period such as the Political Reform Association (1887–91), the National Association (1891–99) and the Political Reform League (1905), with Leader of the Opposition William Massey accepting endorsement from the latter in the 1905 and 1908 elections. The conservatives struggled to contrast with appeal against Seddon and his Liberal political vehicle. William Pember Reeves, when asked of what differentiated the Conservatives from the Liberals in parliament, phrased them as "parties of resistance and progress" respectively.
