Waikato Regional Council staff have collected samples from algae blooms found during an inspection of south-eastern Lake Taupō swimming sites this weekend.
Algal mats and surface water bloom samples were collected from Kuratau Beach, Mission Bay, Motutere Bay, Hatepe, Halletts Bay and Whareroa South Beach.
The samples will be analysed by regional council scientists today to determine whether there are any toxic species. The results will be available later this afternoon and reported to the Toi Te Ora Medical Officer of Health.
In the meantime, members of the public are urged to exercise caution and to avoid entering algae-affected areas.
Taupō District Council staff have this morning erected signage at the six beaches.
