The independent constitutional working group says a lot of Maori appear to have abandoned hope of Parliament ever delivering for them.
The tribal group has been set up to consider how a constitution might be based upon Te Tiriti o Waitangi.
Chair Margaret Mutu says dissatisfaction with the New Zealand system of Government was revealed with poor voter turnout in the seven Maori seats, during last year's general election.
She says less than half of all people on the Maori roll cast their ballot and that's a very low turnout.
Dr Mutu says the independent constitutional working group will consult with iwi throughout the country from next month.
