Deputy Leader of the New Zealand Labour Party

The deputy leader of the Labour Party is the second-most senior politician within the Labour Party in New Zealand. The officeholder deputises for the leader of the Labour Party at party-specific events. Unlike other political party leaders, the Labour Party's leader does not have the power to dismiss or appoint their deputy; both the leader and deputy are elected. In all cases where the leadership is vacant, the deputy leader shall also serve as acting leader until a new leadership election. When the Labour Party forms the Official Opposition the deputy leader typically serves as deputy leader of the Opposition.

Carmel Sepuloni is the current Deputy Leader, elected on 7 November 2023.
