Health warnings issued for Lake Maraetai and Lake Ohakuri
Health warnings have been issued by the local Medical Officer of Health for Lake Maraetai and Lake Ohakuri due to blooms of potentially toxic blue-green algae.
The health warnings mean that people should avoid any activity which results in contact with the water.
These algal blooms have the capacity to release toxins into the water which can cause significant ill-health to anyone who has contact with the water. The toxins can affect the nervous system causing numbness and difficulty with breathing, and also sparking asthma attacks. Contact with the water can also cause skin rashes, stomach upsets and visual problems.
Signage advising the public about the algal blooms will be erected at the lakes.
