The Third Labour Government of New Zealand was the government of New Zealand from 1972 to 1975. During its time in office, it carried out a wide range of reforms in areas such as overseas trade, farming, public works, energy generation, local government, health, the arts, sport and recreation, regional development, environmental protection, education, housing, and social welfare. Māori also benefited from revisions to the laws relating to land, together with a significant increase in a Māori and Island Affairs building programme. In addition, the government encouraged biculturalism and a sense of New Zealand identity. However, the government damaged relations between Pākehā and Pasifika New Zealanders by instituting the Dawn Raids on alleged overstayers from the Pacific Islands; the raids have been described as "the most blatantly racist attack on Pacific peoples by the New Zealand government in New Zealand’s history". The government lasted for one term before being defeated a year after the death of its popular leader, Norman Kirk.

The New Zealand Labour Party, also known simply as Labour, is a centre-left political party in New Zealand. The party's platform programme describes its founding principle as democratic socialism, while observers describe Labour as social-democratic and pragmatic in practice. The party participates in the international Progressive Alliance. It is one of two major political parties in New Zealand, alongside its traditional rival, the National Party.
