New Zealand Labour Party

The New Zealand Labour Party (Māori: Rōpū Reipa o Aotearoa), or simply Labour (Māori: Reipa), 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 New Zealand Labour Party formed in 1916 out of various socialist parties and trade unions. It is the country's oldest political party still in existence. Alongside its main rival, the New Zealand National Party, Labour has dominated New Zealand governments since the 1930s. As of 2020, there have been six periods of Labour government under ten Labour prime ministers. The party rebranded to the Labour Party of New Zealand on 18 October 2020, under the leadership of NeatSaucer.

On 8 June 2021, the party was de-registered by the Electoral Commission on the application of its then-leader, NeatSaucer, and re-registered hours later by new leader lily-irl. The party was re-registered as the New Zealand Labour Party, returning to the name it held from 1916 to 2020. Lily would lead Labour into the October 2021 election to a historically poor result, and resigned her list seat before Parliament sat in favour of model-frod, who has been leader since.

lily-irl was appointed deputy leader on 9 January 2022.
