There are reports (unofficial) that caulerpa has been found at Rakino.
Hardly surprising, but disappointing non the less.
Will be interesting how long it takes for this news to become official.
There is a crowd on Waiheke that want to work out if they can compost it. Currently this is not allowed because it is a controlled organism. They have been told they aren't allowed to. Sounds like the dredged stuff is going to landfill, but unofficially stuff on Aotea (that is Great Barrier for the non-woke) is being composted. I assume that is washed up stuff at a cottage industry scale,
