The Otago Regional and the Queenstown Lakes District councils are investigating a potential sediment discharge into the Clutha River from a subdivision - and not for the first time.
Members of the public complained to the councils after sediment from the Northlake development in Wanaka was seen flowing into the river after heavy rain last week.
The developers of the Northlake subdivision, Winton Partners, were served with an abatement notice by the QLDC on Wednesday.
Winton Partners could not be contacted for comment yesterday.
An abatement notice is a warning to the recipient that they are contravening the Resource Management Act.
