New Zealand operates as a constitutional monarchy under a Westminster parliamentary system with Prime Minister Christopher Luxon leading a centre-right coalition government of National, ACT, and New Zealand First since late 2023. The unicameral House of Representatives uses MMP voting, with the next election scheduled for 2026. Recent reforms focus on local government simplification, resource management overhaul, and electoral enhancements.
