"If he's planning on putting money into a private company, I have a few issues with that," the National Party MP said.
"If he wants to start a new SOE, I have a problem with that, too."
Mr Borrows said the Government had already put money into supporting the Whanganui regional economy - and that included $500,000 funding into a feasibility study for the redevelopment of the port.
Mr Borrows said government investment in manufacturing during the 1970s was positive for the region, but it was no longer viable under a "borrower government".
"Whanganui has benefited from government intervention in the past," he said, "but that was a different world."
Mr McDouall said Mr Little's idea was "fantastic", but he also advocated for some government services to be distributed into the regions to boost local economies.
Not surprisingly, both potential Labour candidates for Whanganui support the new Labour policy.
Philippa Baker-Hogan praised the new plan and claimed the current Government had not done enough for the regions.
"This National-led Government is belatedly back-tracking to throw small tasters at provincial New Zealand, like the $500,000 for Whanganui's Port."
Labour's other potential candidate, Steph Lewis, also favoured the idea, and supported more funding for the port redevelopment.
Mr Little said the Gisborne plan would also help with the housing crisis, as the prefabrication plant would improve home affordability.
"Too many logs are being shipped straight offshore without jobs and value being created for locals," he said.
Labour is expected to announce policies for other regions over the next few months.
