When it came to marine threats, such as Mediterranean fanworm, however, it seemed the costs were lumped on to ratepayers through regional councils, and now boaties.
Also, the new biosecurity fee would be paid mostly by boaties in areas free of the worm, while those in Auckland, where the pest was rife and no attempt had been made to eradicate it, didn't pay a cent.
Kerikeri Cruising Club spokeswoman Gill Durham said the council should adopt the system used in Fiordland, where all boats, local or visiting, had to obtain a 'clean vessel pass,' which would spread the cost across all boaties.
Under the current system the estimated 2000-4000 boats visiting Northland each year didn't contribute to biosecurity costs. Requiring boaties to obtain a pass was also a chance to educate them about Northland's biosecurity rules, she said.
NRC chief executive Malcolm Nicolson said the council had spent years lobbying the Government to take a bigger role in marine biosecurity. Initially MPI had seen fanworm as a lost cause, but it had recently begun contributing to the fight, including when the pest was detected at Tutukaka.
Efforts to keep the fanworm out of Northland waters had not been completely successful, but it had been contained.
In the meantime the council could not sit back and do nothing.
Mr Nicolson said the 'clean vessel pass' system had been considered during the consultation process, but the clean hulls programme, as adopted by the council, was more likely to be successful in Northland.
Fiordland had just 300 vessels visiting each year, all of which were inspected. Northland, on the other hand, had up to 4000, with the council aiming to inpsect 60 per cent of them.
Council chairman Bill Shepherd said a significant number of Auckland boaties owned berths or moorings in Northland, so would in fact be contributing to biosecurity costs.
Under the NRC plan about 4000 mooring and marina berth holders, plus boatshed owners, will pay a biosecurity fee of $79.50, with large commercial facilities paying $3737.50.
The bills were sent out last week, the roughly $300,000 raised each year covering about two-thirds of the cost of inspections, education, enforcement and other marine biosecurity activities. The remaining third will come from the general rates take.
