We were warned in 2015 that there would be significant changes to the requirements for a clean hull for vessels arriving in NZ. This arose from the Mediteranean Fan worm issue that was causing problems in the Auckland area. Well the three years are up and the new requirements come into effect May15, 2018. There is a lot of information available from the Ministry - no fewer than 10 downloads in fact. The summary letter from Tracey Bates follows. I will discuss this in full later in the season on Gulf Harbour Radio. This is just to warn you that you will need to keep all records of cleaning, boat hull paint used, and make sure you start your passage home with a clean hull. Patricia Dallas. GHRadio

From Tracey Bates
Compliance with the CRMS will depend on the ability of a vessel operator to submit documentation that shows that one of the following has taken place: The vessel has been continually maintained using best practices The vessel has been cleaned <30 days prior to arrival The vessel is booked to be hauled out within 24 hours of arrival at an MPI-approved facility In the case of yachts, which will be long stay vessels (subject to stricter requirements of a slime layer and gooseneck barnacles only), MPI encourages compliance by cleaning within 30 days of arrival, or having a booking at an MPI approved haul out facility. The skipper must have evidence (photos of the hull and niche areas, haul out receipts, proof of booking, etc.) to show compliance when they arrive. More information can be found in Appendix 2 and Appendix 3 of the guidance document. We have also produced the following fact sheets for recreational vessels arriving into New Zealand
