The deputy prime minister of New Zealand is the second-most senior member of the Cabinet of New Zealand. The officeholder usually deputises for the prime minister at official functions. The current deputy prime minister is Winston Peters of the NZ First party, who has held the position twice before, and will serve until 31 May 2025 due an arrangement under the current coalition government in which he would then be succeeded in the position by ACT party leader David Seymour.
