Four small changes across the system. Big gains over time.

Kaiwaiwai Dairies is a South Wairarapa equity partnership between Featherston and Martinborough, and its six shareholders have long argued for lower-impact dairying. In this case study they walk through the wetland built to capture nitrogen from the farm's peat soils, precision pivot irrigation, reduced fertiliser and cropping, and a solar array that powers the cow shed and irrigators.

Shareholder Aidan Bichan ties the changes back to family, saying the goal is to leave the farm in better shape for the generations still to come.
