Two reports have found discrepancies in the Home of Cycling Trust's proposal for a Waikato velodrome.
One is an economic assessment putting the annual benefit to Waikato at $4.9 million - less than half the $11.5 million earlier identified.
The second report, to be considered by the Waikato Regional Council on Wednesday, casts doubt on the number of cyclists who will use the facility, which could lead to on-going financial support being needed to cover costs.
Regional councillors will on Wednesday consider the Covec economic impact assessment and the Sapere report comparing the velodrome proposal with other indoor velodromes, along with 1026 public submissions, at a full council meeting.
At issue is whether the council will contribute $6 million needed to get the proposed velodrome started.
