Procurement competition is expected to continue to put some upward pressure on lamb prices this month.
However, ever-tightening processor margins might limit just how much higher prices could go, Rabobank's latest Agribusiness Monthly report said.
Schedule prices in both islands had been pushed through the $8kg threshold, the highest price recorded for August.
As of the start of August, the slaughter price in the North Island averaged $8.10 cwt (3% higher month-on-month) while South Island lamb averaged $8 (4% higher).
As was normal for this stage of the season, ongoing price lifts were predominantly driven by procurement competition for an increasingly shrinking supply of lambs for slaughter.
