Hawke's Bay Winegrowers Association executive officer James Medina said as far as his association was aware, the wine industry was the country's only export sector which "gets punished by the Government with an annual indexed tax on its products".
"It seems both counterproductive and counterintuitive to introduce new taxes on the industry which is growing strongly at a time when other key exports are struggling."
He said in 2014 the average Bay grower received $1.55 per bottle of wine gross income before the costs of growing the grapes, while the Government received "a whopping $2.11 per bottle of wine in excise tax, plus GST on top of that".
"So the Government makes around 40 per cent more than Hawke's Bay growers off every bottle of wine sold in New Zealand."
Mr Green said the wine industry had been a "stand-out performer" in the economy over the past decade.
Exports had grown at a compound rate of over 13 per cent per annum, lifting from $435 million in 2005 to $1.33 billion in 2014 and they were expected to reach $2 billion by 2020.
