Waikato iwi are urging the Waikato Regional Council to introduce two Maori seats in time for the 2013 local government elections.
But the regional council has mixed views on Maori representation and a lively debate is expected at tomorrow's council meeting.
The regional council has been preparing to introduce two Maori seats since it last reviewed its voting process in 2006 and reduced the number of elected members from 14 to 12.
A decision to go ahead with Maori representation would mean councillors would have to approve a reduction in their salaries as the same amount of remuneration money would be shared between 14.
The Maniapoto Maori Trust Board, Raukawa Settlement Trust, Te Arawa River Iwi Trust and Waikato Tainui have written letters to the council supporting the move, saying it is a positive and important step forward for Maori.
