Canterbury Regional Council says it's working with Ngai Tahu and the community to try and prevent further illegal discharge of effluent into Te Waihora (Lake Ellesmere).
The White Gold company was recently fined $90,000 in Christchurch District Court for discharging about 45,000 litres of diluted effluent from a Springston property onto land, as well as drains and streams that feed into the lake in October 2010.
That penalty is on top of a $20,000 fine and community service sentence for the farmer manager involved in the offences.
The company had a resource consent to discharge effluent only onto a paddock.
Resource management director Kim Drummond says the council has been working with Ngai Tahu on rejuvenating and restoring Te Waihora since August last year.
He says Ngai Tahu was involved in the court case by providing a cultural impact statement.
Mr Drummond says this show both the council and iwi are working to protect the lake.
He says the council is also working with the community.
