Te Arawa River Iwi Trust co-chairman Roger Pikia hoped that introducing Maori seats would encourage Maori to vote and would enhance rather than replace consultation with tangata whenua.
Tainui chairman Tukoroirangi Morgan supported Maori representation provided it reflected the interests of each iwi in the region.
The constituency boundaries would be determined next year in consultation with iwi should the council adopt Maori seats.
But Waikato Regional Council chairman Peter Buckley said there were mixed views within the council.
"There will be some for it and there will be some who have concerns around it."
Mr Buckley questioned how all the iwi groups could be represented by two members and what the boundaries would be.
He was unsure whether there could be two Maori seats for the whole region or whether it would be split into geographical areas such as east and west.
Maori are 20 per cent of the population of the Waikato region, and since the council was set up in 1989 there have been no Maori representatives elected.
The Bay of Plenty Regional Council has three Maori seats and Mr Buckley said he had received positive feedback on the system.
The council has until November 23 to make a decision.
