A hardline approach is being taken to policing lifejacket and speeding rules on the water this summer.
Maritime New Zealand is funding what it calls a "no excuses" trial campaign and boaties caught breaking council bylaws will be slapped with fines of up to $300.
It's targetting boaties in Northland, Bay of Plenty, Waikato, Hawke's Bay, Canterbury, Tasman, Marlborough and Nelson.
