Iwi leaders are urging the Crown to wait for the Waitangi Tribunal to make a call on who can change Maori land laws, before making any alterations.
More than 500 people attended a series of hui around the country in January.
As a result of those meetings, they are recommending that the rewritten Ture Whenua Maori Act not be introduced to the House next month as planned.
They want to wait for the findings of the Waitangi Tribunal, which heard claims against the government process in November last year.
The reforms will be discussed with Prime Minister John Key in the iwi leaders' hui at Waitangi tomorrow.
