Even though recent figures from New Zealand show that sheep numbers continue to decline, Mike Petersen, special agricultural trade envoy, from New Zealand, says that they may have reached a plateau.A downward trend in hogget and breeding ewe numbers has seen New Zealand’s national sheep flock shrink by 3.2% in the past 12 months, to currently stand at 29.8m head. The largest contributor to the overall decline was the continued change in land use towards dairy on the south island. Drought was another cause.
