The Environmental Defence Society says there is inadequate Maori representation on the new Environmental Protection Agency.
The agency has two people with Maori backgrounds on the board, former Ngai Tahu chief executive Anake Goodall and Taria Tahana from Ngati Pikiao.
EDS chair Gary Taylor says a co-governance model would have been preferable.
''Rather than having one or two Maori, I prefer boards established on a co-governance basis,'' he told Waatea News.
