 Early evidence reported by the teams surveying boats at anchor in Northland is that around 85% of boats, both local and visiting the region, are free of marine pests.
It confirms a steady increase in the number of vessels ensuring their boat’s hulls are clean and free of marine pests “It shows that most of our boatyards and haulouts not only in Northland but in regions where visiting vessels originate are doing a great job of cleaning,” Kathryn Lister of Northland Regional Council. “Boat owners are also to be credited and thanked for understanding the need to complete this maintenance before they arrive.” Kathryn says this is in large part due to work done in the regions, including Auckland and Bay of Plenty in both education and surveillance. For example, Auckland Council run a summer Outreach programme that sees friendly ambassadors at marinas and busy boat ramps, raising awareness with boaties and the public on marine biosecurity. Rules were introduced to Northland in 2010 to help ensure that marine pests could not be transferred to pristine places on moving vessels. Since then, the councils involved in the marine biosecurity partnership have worked hard to educate and inform boaties about marine pests, the harm they can do, and the need to check and clean boats. Many thousands of boats visit Northland each summer, many from Auckland. Some marine pests are prevalent in Auckland, but are not present in the majority of Northland’s harbours. Boats entering Northland or moving between the regions different harbours can have no more than a slime layer and small patches of visible fouling, according to the region’s biofouling rules.  A citizen science project has captured the curiosity of young Kiwis and is emerging as a potentially powerful marine biosecurity tool.
Marine Metre Squared – or Mm2 – encourages communities to explore what is living on their local shore and get involved in long-term monitoring by observing and recording changes on their coastlines. Mm2 is be a useful way for communities to investigate issues of local concern that may impact local biodiversity – such as the establishment of pest species. By having many eyes (and hands) searching along the coast, everyone can be on the lookout for unusual looking things, report them to their local government and aid in protecting Aotearoa’s unique coastline. Anyone interested in learning more about the Mm2 programme is invited to visit the website here Please add these species to your list of species to look out for: The sea squirt Clavelina is emerging as a concern and we are working to understand more about how it may impact our coastlines. Clavelina forms large colonies on hard surfaces (including marinas and rocky shores) and also attaches to boat hulls and there is a high chance it will have the edge over native species when it comes to competing for food and space. The sea squirt Clavelina lepadiformis has been found in several locations and is emerging as a concern because of its ability to quickly form large colonies. Clavelina oblonga is only know to be present at one site in Aotearoa; Smokehouse Bay at Aotea Great Barrier Island. Clavelina lepadiformis is distinctive: it is called a ‘lightbulb tunicate’ because with its transparent tubes and white, yellow or pink bands, it can look like a glowing light bulb. It was recently found in Gulf Harbour and has been observed on a number of vessel hulls in regions outside of the known established populations – giving rise to concerns that it may be spread by moving vessels.

 The Bay of Plenty Regional Pest Management Plan 2020 – 2030 became operative in December 2020 and contains new rules to protect the region’s marine environment.
Rule 1 - The occupier in charge of a craft moving to, or within Bay of Plenty waters must ensure the hull is sufficiently cleaned and antifouled, so that the hull has no more than a slime layer and/or barnacles. Rule 2 - All aquaculture equipment (including ropes and floats) used within Bay of Plenty waters must not have been used outside Bay of Plenty waters or used within a known pest incursion zone in the Bay of Plenty. By directly targeting the movement of vessels and the marine industry equipment, the rules ensure that craft owners and the marine industry take responsibility for helping to stop the spread of marine pests. Read the Regional Pest Management Plan  In a pivotal move for marine biosecurity in the Auckland Region, marine pests are now listed in Auckland’s Regional Pest Management Plan. This extends effective biosecurity protection from the land into the sea, providing vital protection to the Hauraki Gulf and its islands.
Auckland Council is introducing new rules from the Regional Pest Management Plan 2020-2030 (RPMP) that cover the entire Auckland region, and also regulations that affect those who live and visit the Hauraki Gulf and islands given effect by the Hauraki Gulf Controlled Area Notice. Through a phase in process, Auckland Council will assist commercial operators, private users and landowners within the Hauraki Gulf in understanding and complying with the rules over the next few years. Important points from the new RPMP are: Auckland region-wide:
