Several thousand eels have died in mysterious circumstances in a Southland stream — prompting an investigation by environmental officials.

Thel deaths in the Low Burn Stream near Mataura.

Environment Southland compliance manager Donna Ferguson said the team estimates several thousand eels had died over about a 10km distance.

“Our staff have spent extensive time out investigating any potential causes and we have identified one potential source. We have sent a suite of samples away for testing and will continue to look for further evidence.”

It is likely that people would continue to see dead eels as they make their way down the waterway and into the Mataura River.

“We know the deaths of these eels and other stream life in the area will be distressing. This is an active investigation and our teams are working hard to establish the cause.

"As this is an open investigation, we are unable to make further comment."

Environment Southland asked people to please avoid contact with the water, and report any further eel deaths to the compliance team.
