A 51 per cent shareholding from the regional council is proposed, with a contribution of about $5.46 million through to the 2018-2019 year, with investors from Hawke's Bay and the Gisborne region holding the remaining 49 per cent interest in a holding company, which would be formed especially for the purpose.
But any investment by the council would require the Government and/or KiwiRail to fully fund the restoration of the railway line, satisfactory leases on the line and locomotives, and agreements on freighting of logs and fruit and vegetable produce beyond 2020, to ensure the long-term viability of the service.
A spokesman for Mr Brownlee said yesterday the Minister wrote to NGR after meeting with them in December and the letter made it clear the government would not support the initiative.
NGR is chaired by former Napier mayor and current regional councillor Alan Dick who said at the weekend that negotiations with the government were at "a sensitive stage".
Mr Dick said last night the group was contesting the Minister's response which he said "contained significant misunderstandings of our proposal".
"We may not have communicated as well as we should have," he said.
"As far as I'm concerned the matter is not determined at all. The [Minister's] misinterpretation is fundamental in terms of our proposition to the government and the safeguards and risk minimisation that's in it for them."
NGR had responded to the minister's letter.
A spokesman for Mr Brownlee confirmed the Minister had received a reply to his letter.
"We are going to be responding to [NGR] again but I don't think it will be changing anything."
Mr Dick said under NGR's proposal the Government was being asked to spend $3-5 million "to repair their own rail line".
That figure was based on an earlier KiwiRail estimate that the work would cost $3.3-$4.4 million, and allowing for additional work that may now be required. He said regardless of the Minister's's stance he wanted the regional council to pursue the proposal.
"I would still be pressing the council to keep it in the annual plan and let the public of Hawke's Bay express their opinions because a lot of things can happen in a few years in politics and it's election year."
Submissions on the plan close on May 12.
