More complaints about cattle owned by the Chief Justice Dame Sian Elias roaming in waterways have been received by the Canterbury Regional Council.
Dame Sian and her husband, businessman Hugh Fletcher, were investigated in January after cattle from their North Canterbury station were photographed cooling off in a high country lake.
They were warned, but not fined, after the investigation found no evidence of faecal matter in the lake - just a few cowpats on the shore.
Environment Canterbury spokesperson Kevin Heays told Morning Report since then it has received three complaints about their farm, but there was no definitive proof the law had been broken again.
"To fence off Lake Sumner is one humungous job, as you can imagine, tens of kilometres of fencing. However, I can say that management and the owners have been extremely co-operative around that. They've started doing that already, they're keeping the cows out of the paddock that surrounds the lake and they have started their fencing, with one or two kilometres done already."
