Environmental groups say a court ruling confirms the approval system for oil and gas drilling waters is a box-ticking exercise, and draft regulations will further reduce public scrutiny.
The High Court has rejected Greenpeace's challenge to the Environmental Protection Authority's handling of Texan oil company Anadarko's application to drill exploration wells in deep water off Taranaki and the Canterbury coast.
Greenpeace claimed the EPA was wrong to accept Anadarko's environmental impact assessment as complete, because the company did not provide sufficiently detailed contingency plans on how it would respond to a well blowout.
But Justice Alan Mackenzie found the EPA's role was limited to assessing whether an application contained information listed in New Zealand's Exclusive Economic Zone (EEZ) Act, rather than assessing the merits of the content.
Another agency, Maritime NZ, decides the merits of a company's full discharge management plan which includes detailed emergency response documentation.
