Clean Hull Requirements for arrival in NZ

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

I sent some feedback to MPI and got the following from them which throws more light on the subject.

The recent web update aimed to streamline the number of documents linked to the site. However, if you are still having trouble finding what you are looking for, I would suggest the following as the most relevant for yachts:

· Guidance Document for the CRMS (in particular, appendices 2-3)

· Frequently Asked Questions about the CRMS

· CRMS Recreational Vessel Fact Sheet

MPI has also published an article on the cruising website that explains the requirements for yachts, which has gotten very positive feedback from the cruising community for its clarity: .

As you’ll see from these documents, MPI has not made it a requirement that the vessel is hauled out to be cleaned prior to arrival-vessel owners are welcome to clean their own vessels, provided they follow all local regulations and carry documentation that all hull and niche areas have been thoroughly cleaned (such as date-stamped photos of the cleaned hull, and records in the vessel’s log book). From my interactions with international cruisers and various cruising groups throughout New Zealand and the Pacific Islands, the general consensus is that most vessel owners perform some form of cleaning prior to departure anyway, and we have not gotten much of response indicating that the requirements will be unduly onerous for vessel owners.

We have also updated the materials to be sent out in this year’s yacht packs to reflect the new requirements. The yacht packs can be found on the NZ Customs webpage, as they are technically issued by Customs. I have attached some of the updated biofouling information to this email (note that these updates have not yet been reflected in the version of the yacht pack on the Customs page).

I hope this has attended to some of your concerns, and we will take your comments into consideration for further revisions of the webpage. Please feel free to get in contact with any further questions.
