Wood chips are transported by truck to Port Marsden while a small amount of timber is trucked to Auckland and Tauranga to be shipped out.
Mr Broughton said carrying wood chips by rail to Marsden Point would be an option for his company if the rail link went that far.
"Ultimately I am concerned about a loss of regional capability. We need to have good infrastructure and rail infrastructure is shrinking and I challenge anyone whether roading infrastructure is really improving or are they just tinkering with it."
"If roads are going to be Northland's infrastructure of choice, then it needs to be funded with that focus."
Mr Broughton said the rot started 10 years ago when the deep water port was moved to Marsden without any requirement for a rail link.
Former Far North mayor Wayne Brown told the forum there was enough money in the Government coffers for rail if the state highway improvement on the north side of the Brynderwyns was anything to go by.
New Zealand First leader Winston Peters said his party would reinvigorate rail freight and lines and build a link to Northport to handle Auckland freight. "The neglect of rail around New Zealand has become a national disgrace. We must restore such state assets and stimulate the economy in the regions."
Forum organisers are working on a petition to be submitted to the Government and plans are under way to host another forum in Auckland with the Super City's mayoral candidates.
