The South Taranaki District Council is proposing to add an additional seat around the council table, after a representation review recommended a change to the council's makeup.
Councillors met last week to discuss the review which was triggered by the council's vote to establish a Māori constituency.
Representation reviews legally must be conducted every six years, and determine the council's makeup for the following two elections.
Under the new proposal put forward by the council, there would be 13 councillors, two of whom would be elected by a Māori constituency.
A single position - one of the three Taranaki Coastal Ward seats - would be scrapped to make room for the new Māori wards.
