Toxic Algae

Toxic algae is a common name for toxic cyanobacteria - naturally occurring bacteria that live in shallow, stoney rivers like the Tukituki. Some cyanobacteria produce toxins that can be dangerous to humans and animals.

Warning signs for the Tukituki catchment

We know that the Tukituki catchment sometimes has high levels of toxic algae during the summer months.

There are signs at areas where there may be more toxic algae during a typical summer. The risk of contact can change in quickly, so it's important for the public to be very careful and look out for the algae. Toxic algae is easy to spot, and the signs show images of what to look out for. 

Te Whatu Ora are responsible for these signs, and updates are posted on the Facebook pages for the Regional Council and Te Whatu Ora.

To find out more about toxic algae and its effects, check out our Toxic algae guide, or more Toxic algae information on the LAWA website.
