At a council meeting this week it discussed a report outlining how each ward in the region was represented.
Moeraki was the most under-represented region with one councillor for every 20,400 people.
Dunstan had one for every 19,113, Dunedin one for every 18,467 and Molyneux one for every 17,800.
A report recommended the council not change its representation.
However, councillors decided to workshop potential changes.
Cr Michael Laws said he did not understand why Mosgiel was in the Molyneux Ward, which also includes South Otago.
"The people of Mosgiel very much identify with Dunedin. They shop here, go to school here."
He also said figures predicting the population growth in the Dunstan Ward, which contains much of the Central Otago and Queenstown Lakes districts, were incorrect.
"Population projections are much more extreme than in this paper. I could easily make a case for a fourth member there."
Cr Ella Lawton agreed and said the council needed to assess the way the councillors were split.
"We owe it to ourself to have a blank slate."
As the sole representative of the Queenstown Lakes area, more emphasis needed to be placed on representatives there, she said.
"Driving seven hours every week for these meetings is taxing. I can see why there's not people putting their hand up."
Cr Sam Neill said he thought Crs Laws and Lawton were making the discussion "more complicated and important than it really was".
"I'm perfectly happy with what has been proposed."
He admitted he would be the least likely to be impacted.
Cr Bryan Scott said historically there was a lack of work from the regional council in the Queenstown area, and that was because the council had not had representatives from there in the past.
"I think we need to workshop and put our thinking caps on rather than slipping into the status quo."
Council chairman Stephen Woodhead said there were people standing for election in Queenstown, they just were not elected.
Councillors signed oaths to work for the good of the whole region, not just their ward, he said.
