Opposing was Councillor Rick Curach who said the original decision effectively meant the performance centre was off the radar because it would be a 10-year plan discussion.
Councillor Gail McIntosh said some councillors discussed the decision after the September 6 meeting and decided there would be efficiencies in doing the three investigations at the same time. "It was a bit of a slip up."
Councillor Matt Cowley said doing the investigation in 2016-17 would maintain flexibility in the master plan and ensure the community had an informed discussion.
Councillor Steve Morris said he would like to kick the project into touch, but he understood it was not the will of the majority. Councillor Leanne Brown said it was logical to get the steps right.
Councillor John Robson feared that it was another $100,000 that would go into a pot and come out with something that was less than the quality needed to make a decision.
Councillor Catherine Stewart opposed bringing it back into 2016-17, saying that if and when the city needed a performance centre, it may need more than 1000 to 1200 seats.
Opponents of shifting the investigation back to the current financial year were Councillors Rick Curach, John Robson and Catherine Stewart. Supporting were Mayor Stuart Crosby and Councillors Leanne Brown, Kelvin Clout, Matt Cowley, Bev Edlin, Bill Grainger, Gail McIntosh and Steve Morris.
The council had previously agreed to spend $300,000 to develop a detailed business case for a new museum that would include looking at the alternative site on Cliff Rd, and $400,000 to develop a business case for a "fit-for-purpose, future-proofed" city library.
