A Hawke's Bay wine producer wants a pro-genetically modified organism speaker to be banned from a national conference this week.
John Bostock said New Zealand Wine's conference, Bragato, was weighted towards pro-GMO representatives.
He said the first day of the conference included the chief executive of Futurity Food, Jack Bobo - who Bostock said was known to push genetic modification.
"It's unbelievable that New Zealand Wine is spending significant money to fly a GMO spin doctor from the United States to GM Free Hawke's Bay to take centre stage at the annual conference, providing a free platform for him to promote GMOs," Bostock said.
