For frozen french lamb racks, the benchmark price in the US rose to US$8.25/kg from US$7.60/kg in February, US$6.50/kg a year earlier and hitting the highest level since January 2013. In Europe, the benchmark rose to 16.75 euro/kg from 16.50 euro/kg in February, 12.75 euro/kg a year earlier and the highest since April 2012.
The benchmark lamb flap price increased to US$5.75/kg from US$5.60/kg in February, US$3.80/kg a year earlier and at the highest since September 2014, AgriHQ said.
AgriHQ's Brick noted that it has been easier for meat processors to source lambs in the South Island than in the North Island, where processors have found it "particularly difficult" to source lambs for slaughter in recent weeks.
"Weather conditions have fallen in farmers' favour since late summer, and they are therefore sitting on what numbers they have until they reach desirable kill weights," he said.
Brick said industry estimates for lamb numbers this season also appear to have been too high, which means it's debatable how many lambs remain to be slaughtered.
Meat is New Zealand's second-largest commodity export product behind dairy.
