Lead agency Sparc has set a deadline for the Home of Cycling Trust to secure 80 per cent, or $22.8 million, of the money needed for the project.
It will enter discussions with short-listed bidders Auckland and Palmerston North if the Waikato/Bay of Plenty bid does not deliver. Sparc is contributing $7 million towards the indoor centre.
Covec's economic impact assessment, commissioned by the Waikato Regional Council, found discrepancies between its economic assessment and the initial report by APR Consultants on behalf of the trust.
Covec put the significant differences between the two economic impact assessments down to the Home of Cycling Trust commissioned report ignoring income tax, GST and other leakages from the regional economy when working out the flow on effects.
It also said that there was an incorrect assumption that carded athletes earned $60,000 a year, when the majority received much less.
APR's estimated $11.5 million economic benefit for the indoor velodrome and Bike NZ headquarters was also much higher than Taupo's and Manawatu's bids, which were $1.04 million and $1.51 million respectively.
The Sapere report found the proposed location of the velodrome between Hamilton and Cambridge was a deterrent, as most people would have to travel to get there.
