Councillor Jenny Duncan said council had no control over big ticket items such as the wastewater treatment plant and damage from last June's record-breaking rainfall event. "Take these two items out of the plan and the rates increase would be minimal. But these items are out of our hands."
Mr Vinsen was also concerned about a 4 per cent increase in council personnel costs which he said could be pared back to no more than 2 per cent. And he questioned the iwi consultation budget of $150,000 .
Councillor Philippa Baker-Hogan said she did not believe operational costs had been looked at closely enough and also expressed concerns about the costs of the Sarjeant Gallery.
The 2016-17 annual plan has added three significant changes to the 10-year plan.
The first is the treatment plant rebuild; the second is a special rate to cover the clean-up costs of the June weather event (1.7 per cent of the rates); and the third is the Westbourne-Gonville stormwater project (0.3 per cent) to reduce the effect of ponding and flooding in those areas which occur in the wake of even medium-sized rainfall events.
The annual plan is out for public consultation until May 6.
