New Zealand public law

The Centre explores New Zealand public law issues concerning the constitution, administrative law, and a wide range of areas of governance.

Our focus

We analyse and discuss issues pertaining to New Zealand public law. This includes core constitutional law issues related to the nature and limits of the power of the New Zealand state, the constitutional status of the Treaty of Waitangi, and the past and future of the country’s constitution.

Other issues we examine include administrative law and aspects of governance, such as resource management, immigration, the public health system, criminal justice, and the regulation of the economy.

The Centre holds an annual Government Law Year in Review half-day seminar, where new developments in many of these areas are discussed. We also hold public lectures by academics, judges, and other state officials.

Our research, publications, and projects examine many different aspects of New Zealand’s system of public law.
