The Shadow Cabinet of Judith Collins formed the official Opposition in the 53rd New Zealand Parliament, and previously in the 52nd Parliament. It comprised the members of the New Zealand National Party, which is the largest party not a member of the Government. On Collins' dismissal as leader on 25 November 2021, the cabinet essentially ceased to exist, but what remained was de jure led on an interim basis by her deputy leader, Shane Reti, until the next leadership election. The cabinet was succeeded by that of Christopher Luxon.
