"I'm concerned about the affordability of Crankworx for local families and the cost for them to attend," Ms Tapsell said.
She asked council chief executive Geoff Williams to get staff to report on the issue.
Mayor Steve Chadwick said she understood Ms Tapsell's concerns and supported her request.
But deputy mayor Dave Donaldson, who is on the Crankworx board and stood down from the debate but took questions from councillors, said it would probably be too late to make any changes because tickets had been on sale for months.
However he said he had received similar feedback about ticket prices.
Mr Williams said a report would came back to the next council committee meeting before the start of Crankworx at the end of March.
