Founder and CEO of Halter, Craig Piggott

Craig Piggott

Founder and CEO of Halter

Several years ago, between working as Mechanical Engineer at Rocket Lab and returning to his Waikato dairy farming roots, Craig Piggott saw an opportunity to innovate.

After spending time in both the agriculture and engineering industries, Craig realised how an important gap could be filled, giving birth to a truly transformational tool; Halter.

Founded in 2016, Halter leverages artificial intelligence to guide cows around the farm, set up virtual fences and detect health events with the ultimate aim of creating a future of farming that is more simple, ethical and sustainable.

Since its launch, Halter has grown to a team of 130 employees whose work has received widespread recognition and investment from both New Zealand and American venture capitalists. Halter has won awards at the 2017 New Zealand Innovation Awards and 2021 NZ Hi-Tech Awards. 

Craig was also a finalist for the 2018 NZ Hi-Tech Young Achiever Award and EY Entrepreneur of the Year award, and won the NZ Hi-Tech Young Achiever Award in 2020.

While he leads a business making waves in the agri-tech industry, Craig firmly believes it is having the opportunity to work on something meaningful, solving tough problems, and being part of a high performing team that brings him the greatest reward.
