Health warning issued for Rotorua Lake

Another health warning has been issued for a Rotorua lake and more are expected to follow.

Water testing at Gisborne Point and Hinehopu at the eastern end of Lake Rotoiti has revealed a significant bloom of blue-green algae or cyanobacteria.

Acting medical officer of health Dr Paul Martiquet said Environment Bay of Plenty's water sampling tests confirmed the blooms in those two areas.

"It's just a seasonal thing ... this is not uncommon for this time of year," Mr Martiquet said.

People are being asked not to use the lake for recreational purposes and to avoid skin contact with the water.

They have also been warned against drinking water from the lake.

He said there were signs of bloom activity in other parts of Lake Rotoiti, but further sampling this week would confirm the extent.

However, he does expect more health warnings to follow when weather conditions become even warmer.

A health warning remains in place for Lake Okaro, 25km south of Rotorua.
