STOP exotic caulerpa seaweed

Exotic caulerpa is a fast-growing seaweed that threatens our native marine ecosystem. It has been found in parts of the Bay of Islands, including Te Rāwhiti Inlet, where there are legal restrictions in place.

To help stop it from spreading:

  • Check for seaweed on your anchor, chain and gear before you move to a new location.
  • Remove any seaweed you find, bag it securely and dispose of it onshore in the rubbish.
  • If you can’t bag it securely, return it to the water where it was found.
