For thirty years, caulerpa seaweed has been known as the single worst marine weed pest
We have it in New Zealand on Aotea Great Barrier Island and Ahuahu Great Mercury Island
But Northland Regional Council is determined to keep it out of Te Tai Tokerau due to the risks to local environment, cultural practices, marine industries and traditional collection of kaimoana
Deputy Chair of Northland Regional Council, Councillor Jack Craw has a 40 year career in biosecurity behind him and joins us now
