Tens of thousands of farmers could be affected by a "knee-jerk" recommendation to further regulate semiautomatic firearms, Federated Farmers says.
Parliament's Law and Order Committee this month released its report after an inquiry into illegal firearms, with 20 recommendations.
Federated Farmers national board member Katie Milne said the lobby group strongly opposed the recommendation that semiautomatic firearms be further regulated, and that permits be required to lend firearms to other gun licence holders.
"This is a case in which the National Party needs to back up its election promise of less and better regulation," Milne said.
Semiautomatics were the best way of shooting pest species like rabbits, hares and Canada geese, she said.
