Mediterranean fanworm has been found in Whangarei Harbour, Northland Regional Council Biosecurity Officer Jillian Fulcher, is calling for recreational divers/snorkelers to report any sightings.
This pest is an unwanted organism and is present in New Zealand. It has been detected in Lyttelton Port and in a number of locations in the wider Waitamata Harbour in Auckland.
If you suspect you have found this pest anywhere else in New Zealand (apart from Lyttelton and the Waitemata) please call 0800 80 99 66
If you are the owner/operator of a moored boat, you can help prevent the spread of this marine pest by ensuring your boat’s hull is clean and well antifouled.
The Mediterranean fanworm is a marine animal that is typically found in estuaries or sheltered sites, found at depths of anywhere between one to 30 metres.

The dispersants being used to break up the hundreds of tonnes of oil leaking from the grounded Rena could be “more harmful than the oil itself”.
Maritime New Zealand (MNZ) has used Corexit 9500 to help break up the oil, but University of Southampton oceanography lecturer Dr Simon Boxall said using dispersants could cause unnecessary harm.
The UK banned the use of Corexit dispersants in 1998 and Sweden has a blanket ban on all dispersants in the marine environment, Boxall said.
“In their raw form some dispersants can be very toxic and I believe will do more harm than good,” he said.
“They are more harmful than the oil itself and they are not less toxic than dishwashing liquid.
“Dishwashing liquid doesn’t carry hazchem advice and you don’t wear protective clothing and masks to do the washing up. In this case - with limited knowledge of the region - I’d advise caution on use of dispersants.”

Despite a six hour rescue attempt, Department of Conservation staff were unable to refloat a sperm whale grounded on a Far North beach.
The 12 metre marine mammal grounded itself approximately 20-30 metres off-shore from Coopers Beach (a popular holiday destination in Doubtless Bay, 50 kilometres south of Kaitaia) sometime this morning. According to DOC Incident Controller, Jonathan Maxwell, DOC staff, aided by members of the local community, battled choppy sea conditions and 20 knot on-shore winds to prevent the whale from coming ashore. “We had a DOC boat and the Far North Coastguard boat in the water and attempted to move the whale out of the shallow water using ropes and nets. Unfortunately a spring tide and wave conditions had moved the whale too far up the beach for us to be able to free it,” Mr Maxwell added.Continue Reading "Attempts to rescue stranded sperm whale fail"
