A West Coast farming company has been fined $66,000 on seven charges relating to dirty dairying.
In sentencing Moir Farms Maimai Ltd, Judge Paul Kellar commented on the company's "extensive history of non-compliance''.
The company was convicted in the Greymouth District Court last month, but Judge Kellar's written decision was released only this week.
Moir Farms owns six dairy farms in the Mawheraiti and Maimai valleys. The charges, relating to two farms, include illegal and unconsented works in the bed of an unnamed tributary of Casolis Creek during the construction of an extra effluent treatment pond, and illegal discharges of effluent to land and water.
Tests showed that the farm discharges led to a massive increase of e.coli (faecal content) and high levels of ammonia.
