Boaties will now have to think twice about where they anchor in the Hauraki Gulf. Those without holding tanks or treatment facilities will not be able to stop overnight in such popular spots as Kawau, Waiheke and Great Barrier Islands because the anchorages are less than 500 metres from shore.
Boaties have had two years to prepare for the changes, which prohibit vessels discharging sewage closer than 500 metres from shore or from a marine farm. Water depth must be at least five metres. Breaking the laws could attract a fine of up to $200,000 under the Resource Management Act, but that level of punishment is unlikely.
