Dr Shaun Fogie's farm is only 3.3 hectares, but his livestock are a bit smaller than conventional farm animals.
Fogie farms thousands of dung beetles – and sells them to farmers and local councils.
He says they're a natural and efficient way to to get nutrients down into the soil and could help rehabilitate New Zealand’s waterways.
Dung beetles improve soil structure and keep pastures clean, which helps mitigate runoff into streams during high-rainfall events.
Fogie's dung beetles originally come from south-west Europe and southern Africa and reproduce rapidly, he says.
