The Trust's initial feasibility report – the Master Plan (2007) – included the options of:
- building a new multi-purpose stadium with a roof (capacity 30,000 people) – $188 million
- building a new multi-purpose stadium with no roof (capacity 30,000 people) – $131 million
- upgrading Carisbrook Stadium – four options ranging from $29 to $69 million.
The Trust's report favoured the first option as the only "long-term solution" that would "provide significant community benefits, both socially and economically".
DCC agreed, and investigation into the first option continued. Otago University, which was located directly alongside the proposed site, had joined in. The university would contribute to the cost of the stadium, which would include new spaces for university use.
