Multiple convictions highlight environmental enforcement as improper effluent discharges draw penalties from regional authorities.
In late 2025, Waikato Regional Council successfully prosecuted three separate dairy effluent cases, resulting in fines totaling $108,000 for two farmers and two farming companies after unlawful discharges were found. These convictions arose under New Zealand’s Resource Management Act (RMA) for improper effluent irrigation practices that led to contamination risks in the Te Awamutu region between March and August 2024.
In the Huntly District Court on December 1, Judge Jeff Smith imposed penalties on Stella Farming Ltd ($44,000), LTB Farms Ltd ($26,000), individual farmer Scott Blundell ($2,000) and Michael Davison ($36,000) for the environmental breaches. Blundell was also sentenced to 100 hours of community service related to his role in one of the offences, underscoring that consequences can include non-monetary penalties alongside fines.
Waikato Regional Council’s enforcement manager Patrick Lynch stressed that correct effluent irrigation is an essential part of responsible dairy farm management, and that poorly executed systems can cause significant harm to waterways and surrounding land when misused or neglected. These convictions reflect ongoing efforts by regulators to uphold water quality standards and protect environmental resources in a region with intensive dairy operations.
The breaches involved improper use of effluent irrigators, which can lead to runoff entering streams and tributaries if not managed with appropriate infrastructure and oversight. In the case of Stella Farming Ltd, an additional charge was added for failing to exclude livestock from a waterway, amplifying the environmental concern and penalty.
For dairy producers and environmental compliance officers, this series of convictions serves as a clear signal that regulatory scrutiny remains high in New Zealand’s dairy sector, particularly regarding effluent management. Effective infrastructure, regular maintenance and adherence to effluent discharge standards are crucial to avoid both environmental harm and costly legal penalties.
