Federated Farmers says the current low price of lamb is unsustainable.
New Zealand lamb is being sold in the UK at almost half the price of meat produced by British farmers.
Bruce Wills says it's because farmers here are more efficient, but the returns they're seeing aren't good enough.
"I'm selling lambs this season at a good 30 to 40 percent less than I got last year so that's a significant drop. It's a drop of well over a third and it's not sustainable."
Mr Wills says a drop in demand for lamb has pushed prices down.
He says New Zealand lamb is usually sold in the UK during their 'off' season.
"From time to time the shoulders of both those seasons cross over, there can be some tension - a bit of pressure, I guess we're all there to make some money and supply the market."
