Just over thirty years ago, in the High Court decision Huakina Development Trust v Waikato Valley Authority, Justice Chilwell famously stated: “There can be no doubt that the Treaty is part of the fabric of New Zealand society.” ¹ At a symposium celebrating 30 years of the Huakina decision, Tom Bennion described the judgment as “a marker, a significant new structure sticking out in the legal landscape, indicating the shape of arguments to come.” This collection of work brings together a range of arguments for our time concerning the meaning and importance of the Treaty of Waitangi, shaped by different perspectives on its context and history.
