New Zealand's constitutional journey began with the Treaty of Waitangi in 1840, setting the stage for a unique partnership between Māori and the Crown. Over time, the country moved from British control to independence, developing its own constitutional framework.

Key milestones include the 1852 Constitution Act, 1947 Statute of Westminster adoption, and the 2004 Supreme Court establishment. These changes reflect New Zealand's evolving identity and governance, blending British traditions with local innovations.
