Halter, a New Zealand tech company specialising in virtual fencing and animal management technology, has raised $165 million in a Series D fundraising round, valuing the company at $1.65 billion.

Started in 2016, Halter’s solar-powered, smart collars were guiding thousands of cattle by sound and vibration cues, allowing farmers to get rid of fencing on paddocks.

CEO and founder Craig Piggott says the technology helps farmers be more productive - and sustainable.
