A pending deal between corporations and the Government has raised concerns that the Environmental Protection Authority's independent status could be undermined.
Minister for the Environment, Nick Smith, has been cited as a potential selector of the EPA board of inquiry in the future, which could affect its power.
This comes shortly after the EPA declined two applications for seabed mining, and organisations such as Greenpeace have expressed concern that this is why the changes to the EPA are being considered.
Greenpeace's executive director, Dr Russel Norman, has referred to the move as a "dirty back-door deal" which could strip the EPA of its current power.
"It's like being able to choose one of your friends to mark your exam paper rather than having someone independent do it - it's ludicrous."
