Labour's Dover Samuels has said publicly that the legislation is seriously flawed.
Maori Party co-leader Tariana Turia criticised the delays, and today the Marlborough District Council has said that thethe marine farming industry is stagnating and Labour's reforms are unworkable.
Mr Heatley says he's not at all surprised at growing criticism that progress in aquaculture has been hopeless for Maori.
"Not one single new Aquaculture Management Area (AMA), where marine farming isn't already happening, has been created anywhere in the country in the 894 days since the reforms came into effect."
As part of the reforms, which came into force in January 2005, Maori were promised 20% of existing aquaculture space, and 20 per cent of future space.
