A select number of Waikato dairy farms are testing cow collars using a "Cowgorithim" to keep an eye on their herds.
Smart-cow startup Halter is a solar-powered, GPS-enabled collar for cows which enables farmers to shift, manage and monitor their herds remotely.
Halter is currently working with Waikato dairy farmers using a patented technology called "Cowgorithim" to guide cows around the farm using sound and vibrations.
Pete Morgan, who runs 630 cows in the Waikato said he couldn't wait to start using it, as it would save him "around three hours of work a day".
"Right now, I'm incredibly challenged to find enough time and labour to manage the farm. The ability to control herd movement and drafting remotely, while using virtual break fences to precisely manage grazing will profoundly reduce my workload."
