"This is really important for our region for our regional brand, not only on a national level but on a global level.
"I make this call in good faith - I am more than happy to work really closely with Craig on this for what is good for our region," he said.
Tukituki MP Mr Foss didn't say whether he would work with his Labour colleagues, but said: "I am always Backing the Bay."
"I stand for ensuring our region has every opportunity to grow and succeed, balanced, of course, with protections for our stunning environment." He said Labour cannot have it both ways. "They cannot, on one hand, deny our growers the opportunity to export goods to markets around the world under the Trans-Pacific Partnership, and, on the other, say 'GMO-free' is a unique marketing opportunity internationally."
Member for Ikaroa-Rwhiti Ms Whaitiri questioned whether or not Mr Foss was "backing the Bay". She said from both economic and environmental levels it would be silly not to support Hastings' bid to go GMO free.
"It makes complete sense that we would protect the integrity of our agriculture and growers sector in the greater Hawke's Bay area," she said.
