"The New Zealand Government doesn't get it," Ms Hall said.
"Under the Treaty and UNDRIP, Maori people have the right to design and lead the process for reforming through self-governing legislation, through our own representative institutions.
"The minister [Dr Sharples] is still wanting reforms [regarding Maori Wardens] but who will be the governing authority? The problem is the Crown cannot lead those changes," Ms Hall said.
"The New Zealand Maori Council is the only representative authority with legislation force behind it who represent all Maori."
Dr Sharples said the council still had a role to play in Maori community development. This followed on from 20 hui across the country, led by Te Puni Kokiri in September, for public consultation.
"The overwhelming view was that the New Zealand Maori Council should remain and provide services in Maori communities.
"The council has also advised me that it is currently rejuvenating its structure. I have taken those views on board, and this week Cabinet agreed there would be no changes to the act in respect of the New Zealand Maori Council," Dr Sharples said.
