One of the major issues of the bill was the constraints on quad bike use, many said.
The legislation forbids passengers on quad bikes.
Owner of Hawea Farms Hugh Pearse said this could be to the detriment of animal welfare.
"If I have a crook animal, I can't even take the vet on the bike out to treat him.
"Why should safety regulations come at the cost of our animal's health?" Mr Pearse said.
American legislation classifies quad bikes as an "active single rider machine".
All quads come with signage stating that no passengers are to be taken on the bike.
"The farming industry is being badly affected by the reform."
However, Mr Pearse said a "culture change' had occurred within the industry which is responsible for a 50 per cent decrease in quad bike accidents since 2013.
"Farmers are far more aware of the dangers posed on a farm," Mr Pearse said.
"Accidents on a farm can never be completely avoided.
"Piles of paperwork will not prevent death or injury," he said.
The group will make recommendations to Worksafe around risk management, quad bike training, education and incentive initiatives to ensure a safe and productive future for the industry.
