The Bay of Plenty public are being asked for their views on whether a single set of vessel hull cleaning rules should be developed to help stop the spread of marine pests across New Zealand’s four busiest boating regions.

For several years, the Bay of Plenty, Northland, Auckland, and Waikato regions – alongside the Ministry for Primary Industries and boaties from all over – have been working together to stop the spread of unwanted marine pests like Mediterranean fan worm hitchhiking on vessel hulls.

Greg Corbett, Bay of Plenty Regional Council Biosecurity Manager says while Biosecurity New Zealand manages national rules to minimise the risk of new pest species arriving on vessels from overseas, the regulations for (mainly Kiwi-based) vessels moving around within coastal waters vary from region to region.

“Given our four northern-most regional councils (Northland, Auckland, Waikato and Bay of Plenty Toi Moana) are also collectively home to the country’s biggest boating populations, we think creating better, consistent rules across them is a crucial part of how we respond to the growing threat of marine pests,” he says.

Corbett says New Zealand’s coastline and rich, diverse marine life has long been at the heart of our shared national identity, but as the population – and an associated increase in boat movements – grew, so too did the risks of marine pest spread.

“These pests threaten our incredible coastal playground and its underwater life, including kaimoana. They also pose considerable risks to our tourism and aquaculture industries.”

Corbett said there are a number of potential options ranging from a requirement for a clean hull at all times, only when moving or only when moving to specially identified places, and each option has its pros and cons.

The four northern councils believe there are good reasons for shared local rules governing vessel movements and pests and it’s important they hear what their respective local communities think before advancing the initiative further.

“We’d like to encourage as many people as possible to take this unusual opportunity to have a say on a local authority issue that traverses several different regional boundaries,” says Corbett.

A discussion document outlining the different options, including their pros and cons, can be found on the Bionet website, along with the opportunity to give feedback online.

The two-month feedback period runs from Monday 18 March until Friday 24 May 2019.

Corbett says all the feedback will be reported back to each of the four councils around the middle of 2019 and guide future decisions on whether a single set of vessel hull cleaning rules should be developed.

“Before going down that road, any such proposal for new rules would need to be agreed to by each council, and would follow a formal public process to provide an opportunity for public input.”
