In the latest dirty dairying case, a farm company owned by a Fonterra director has been fined more than $72,000.
Armer Farms, which is owned by Colin Armer had already pleaded guilty to allowing effluent from one of its farms to contaminate a stream and beach.
Bay of Plenty's Regional Council's, Pollution prevention manager, Nick Zaman says the fine is appropriate.
"The degree of checking could have been a lot better, in particular the split hosing irrigator had failed a couple of weeks before, clearly enough hadn't been done in terms of actual checking and maintenance of systems."
Mr Zaman says cases of dirty dairying have risen in the Bay of Plenty area in the past few years and he puts this down to the increased use of intensive farming methods.
