The New Zealand Labour Party (Māori: Rōpū Reipa o Aotearoa) is a New Zealand political party. It describes itself as centre-left and socially progressive and has been one of the two primary parties of New Zealand politics since 1935. Labour was last in government from 1999 to 2008 with Helen Clark as party leader and Prime Minister. Since the party's defeat in the 2008 general election, Labour has formed the second-largest (in terms of parliamentary seats) political party represented in the Parliament of New Zealand, and functions as the core of the Official Parliamentary Opposition. Following the 2011 general election, Phil Goff and Annette King stepped down as leader and deputy leader respectively. On 13 December 2011, the parliamentary caucus voted David Shearer and Grant Robertson to replace them. The Labour Party was established on 7 July 1916 in Wellington, bringing together socialist groups advocating proportional representation and "the Recall" of Members of Parliament, as well as the nationalisation of production and of exchange. Its origins lie in the British working-class movement, heavily influenced by Australian radicalism and events such as the Waihi miners' strike.
