In-water (and beach) hull cleaning
Hauling out is the preferred option for hull cleaning. In-water hull cleaning may be carried out subject to strict restrictions. You must ensure that no contaminants (marine pests or anti-fouling paint) are discharged into the coastal environment during the cleaning process.
Hull cleaning on the foreshore can release contaminants from antifouling paint into the coastal environment.
Boat sewage is a serious risk to human and animal health and to the environment. To continue to enjoy Northland's coast and safely gather and eat kaimoana (seafood), our waters must be kept free of sewage. There are strict rules covering sewage discharges from boats in Northland waters – these apply to every type of boat or craft.
Northland's marine pollution rules
It's illegal to discharge untreated sewage into any coastal waters that are:
- Shallower than five metres
- Less than 500 metres from the high tide mark
- Less than 500 metres from a marine farm or gazetted Maitaitai reserve
- Less than 200 metres from a marine reserve
- Within all Northland harbours* an in the Bay of Islands
*Except, in certain conditions, in the emergency areas within Whangaruru and Whangaroa.
If you suspect a boat is illegally discharging sewage, phone the Northland Regional Council's 24/7 Environmental Hotline 0800 504 639.
Stock in the Coastal Marine Area
To help protect our important coastal marine areas, Northland rules require farmers to keep their stock out of the tide.
When stock get into tidal areas they can pollute the water and cause real damage to important ecological environments.
