Working from 6pm and through the night, Lisa Roach keeps watch on pregnant mares at New Zealand's most prestigious stud nursery in the Waikato, tending to them and helping them give birth.
Roach spends her nights walking around the "nursery paddocks" at Cambridge Stud making sure all is well as members of a new generation of champion race horses are born.
"You treat each one like they're carrying a future Melbourne Cup winner," Roach said of the mares brought to the farm to foal.
