Crucial figures for the $68.5 million Claudelands Events Centre were influenced by city council staff who increased the number of events and inflated the revenue expected in the first three years of operation.
A $30,000 peer review of the original "overly optimistic" 2009 Claudelands business case has revealed Hamilton City Council staff told the original author of the business case, Campbell Consulting, to increase the already optimistic number of events in the business plan by up to 50 per cent.
Staff also used higher revenue projections than those provided in the business case in the council's 10-year budget - inflating the figures in the first three years by between 6 and 11 per cent. But at the same time they lowered the operating costs by 6 to 9 per cent, which made the budgets look more attractive.
Hamilton mayor Julie Hardaker said she was waiting for chief executive Barry Harris to complete his investigation into what happened and refused to speculate on whether the council had been deliberately deceived. Council staff had been unable to explain the variation.
The review by Horwath HTL, commissioned in November after staff alerted the council to the centre's poor performance, said the revenue earning estimates were significantly overstated because of "overly optimistic pricing activity and pricing assumptions".
