Otago regional councillors will consider at a meeting tomorrow whether to review the council's representation in time for elections next year.
Under the Local Government Act 2001, the council is required to review representation at least once every six years.
In its last review three years ago, the council dropped one councillor from the Moeraki constituency.
The council could review representation now or it could choose to wait until 2012, a report to tomorrow's finance and corporate committee says.
If it went ahead, it would have to give the public notice by September 8 and take into consideration community of interest and effective and fair representation.
The council has four constituencies - Dunedin (six representatives), Dunstan (two), Molyneux (two) and Moeraki (one) - which roughly follow territorial boundaries, although Taieri and Mosgiel are included in the Molyneux constituency.
The constituencies complied with the representation to population criteria except for Dunstan which just exceeded the ratio, the report said.
