New Zealand environmental law

Environmental law in New Zealand is an increasingly well defined body of national law that has a specialist court, The Environment Court of New Zealand (Māori: Te Kooti Taiao o Aotearoa), to decide related issues.
History.
The roots of New Zealand environmental law can be traced to the common law of Australia. The increasing environmental awareness of the 1960s led to a specific body of environmental law that developed in many Western countries including New Zealand. Environmental law became more integrated in the 1980s with the passing of the Environment Act 1986 and the Conservation Act 1987. These Acts set up the Ministry for the Environment, Parliamentary Commissioner for the Environment and the Department of Conservation. 
The most significant Act of Parliament concerning environmental law was the passing of Resource Management Act 1991. Issues under the Act are adjudicated by the Environment Court of New Zealand.
