Shepherds Watch Over Merino Flock In New Zealand's Mackenzie Country

FAIRLIE, NEW ZEALAND - APRIL 03: Heading dog Tri waits for work at Blue Mountain Station on April 3, 2018 in Fairlie, New Zealand. The station has 15,000 Merino sheep over 30,000 acres of land. Two full time shepherds plus station owner Roddy Brown and casual workers care for the sheep, mustering on foot with dogs. Merinos are prized for their wool, and are regarded as having some of the finest and softest wool of any sheep in the world. New Zealand is the third largest global Merino supplier, with the NZ Merino wool market valued at approximately US$100 million. (Photo by Fiona Goodall/Getty Images)
