Labour's Napier candidate Stuart Nash has called on his National opponent's employer to clarify his position on the Napier-Gisborne rail link.
Hawke's Bay Chamber of Commerce chief executive and National candidate Wayne Walford has advocated the mothballed line be turned into a cycleway.
Mr Nash said the chamber had been "extremely supportive" of the rail link and there was no role for party politics in the chamber's business.
"Official statements by the then CEO Mr [Murray] Douglas described the mothballing as 'foolish in the extreme', 'a completely wrong decision for short-term gain', and it was 'inconceivable to have a massively productive part of New Zealand (such as Hawke's Bay) without rail'," Mr Nash said.
"As recently as January 2013, the chamber, in its official statements, expressed support for the reopening of the rail line," Mr Nash said.
