Visiting Northland waters this summer?
Northland Regional Council guidance
Boat hulls must be free of any marine pests when you travel to our region. An antifoul, lift-and-wash or waterblast, or (if allowed within your region) an in-water clean by divers just prior to leaving will generally be sufficient.
However, please note that there have been instances where arriving boats which have completed this process have still had Mediterranean fanworm and other marine pests remaining in hard-to-reach 'niche' areas (the base of the keel, bow thrusters, intakes/outlets, prop and rudder areas and even live bait tanks). Boat owners are encouraged to double-check these areas before their vessel is returned to the water.
As in previous years, Northland Regional Council will be contracting local divers to carry out extensive random hull checks during the summer months and intends to inspect 1500 visiting and local vessels between September 2016 and May 2017. Any vessels found to be carrying fanworm will be required to be cleaned at the owners' expense, and the owners may also be subject to a $500 fine.
Please also note that Northland marina operators have separate requirements, which are outlined below.
- In early 2017, public consultation is scheduled to take place on a Marine Pathways Management Plan for Northland, focusing on the human activities that may transport marine pests from one place to another.
Given that biofouling (marine growth) on vessel hulls is the main way that marine pests are spread, Northland Regional Council is looking at introducing rules that set limits for the amount of biofouling vessels can have on their hulls.
In June 2016, we ran an online survey of boaties about the timing and frequency of hull maintenance and any issues they anticipate in regards to possible future hull biofouling rules. The survey drew more than 180 responses and a summary of the preliminary findings is below.

Marinas have put a number of measures in place to ensure they protect their structures against marine pests. To visit a marina in Northland, boat owners will need to provide evidence of complying with a 'six or one' requirement: either an antifoul within the previous six months, or a lift-and-wash within one month of leaving an area infected with marine pests. Receipts are the best form of evidence; however, some marinas may also accept date-stamped photos of a clean hull. Check the image below for more details.
