The New Zealand Labour Party was founded in Wellington.

The New Zealand Labour Party was founded in 1916, emerging from a merger of several socialist and workers’ organizations, including the United Federation of Labour and the Social Democratic Party. Its formation was rooted in the growing dissatisfaction among the working class with existing political structures, particularly around labor conditions, social welfare, and political representation. From the beginning, Labour positioned itself as a party for workers and the underrepresented, promoting democratic socialism, trade unionism, and progressive reform. It was initially a small parliamentary force but gained traction through its alignment with the labor movement and its advocacy for economic justice.

Labour first came to power in 1935, during the Great Depression, under the leadership of Michael Joseph Savage. This victory marked a transformative moment in New Zealand politics. The party introduced sweeping reforms, including the creation of the welfare state, state housing programs, and the expansion of public healthcare and education. Savage and his government emphasized social security and public ownership, laying down a foundation that would shape New Zealand’s identity for decades. This era established Labour as a central force in New Zealand’s political system, with a strong reputation for promoting egalitarian principles.

Over the decades, Labour has gone through several ideological shifts. The 1984–1990 Labour government, led by David Lange, introduced controversial economic reforms known as “Rogernomics” (after Finance Minister Roger Douglas), which leaned heavily into market liberalization, deregulation, and privatization—departures from Labour’s traditional socialist roots. These policies created internal divisions but also modernized the party’s economic stance. More recently, under Jacinda Ardern, Labour re-emphasized progressive values, focusing on climate change, child poverty, and social inclusivity, winning a historic majority in 2020. Throughout its history, the Labour Party has continuously adapted, balancing its foundational ideals with the evolving political and economic landscape of New Zealand.
