"We need investors who will invest in the land and buildings. We've got interested parties that will do that. One option is a bunch of local investors get together and we potentially could be part of that if we want to be."

Two weeks ago, Jones announced the Provincial Growth Fund (PGF) would invest $60,000 towards the development of Otago's Economic Development Strategy and a further $820,000 in the Dunedin Waterfront Project.
Dunedin City Council will receive $820,000 to complete a full feasibility assessment and development of a business case for the project, which will include engineering, environmental and commercial feasibility.
Jones said the funding in Otago has set a precedent for the likes of NDC to do likewise, although there was obviously a criteria to follow.
"The PGF has scope for working with the regions and a feasibility study is often the first port of call if they want to seek input from the Crown. I'd encourage them to submit an application."
He said his ministry has a broad mission that included wealth creation and job growth in regions, particularly in large-scale projects like the size planned by NDC.
The Whangārei District Council said since it has not received a resource consent application on the proposed Riverside Dr development yet, it could not comment on the project's impact on existing infrastructure.
Any application would be a very comprehensive document that would include a wide range of technical reports commissioned by and paid for by the developer, including assessment of the development's impact on traffic and infrastructure, spokeswoman Ann Midson said.
"Council's policy is that a developer pays the costs of the impact of the development on public infrastructure."
