Cleaning your boat

Keeping your hull clean has lots of benefits. To protect our marine environment, there are rules about how and where you can do it in Northland.

Why clean my boat's hull?

A clean hull is important to help keep a vessel in good shape and improve its fuel economy and speed. Having a hull free from hitchhiking pests also helps protect Northland's precious marine environment.

How do I keep my hull clean?

Antifouling paint cover is the easiest way to do this. Regular haul-outs for cleaning your hull and reapplying antifouling is crucial. However, as the ingredients in antifouling paint – including copper – can harm marine life, they must be applied and removed with careful consideration.

Where can I clean my hull?

We advocate the use of dedicated boat maintenance facilities for routine maintenance, including hull cleaning between antifouling.

No hull maintenance can be undertaken on the foreshore. This includes the cleaning, scraping, sanding, blasting, painting or anti-fouling of a vessel hull on the foreshore.

The only exception is at an authorised facility, such as a consented grid (with approval of the grid owner and following grid rules).

In-water hull cleaning can be undertaken in limited circumstances, as described below.

In-water hull cleaning rules

In-water cleaning of vessel hull and niche areas or structures in the coastal marine area or a river is a permitted activity, provided:

  1. the vessel or structure has not been in foreign territorial waters, unless a) since arrival in New Zealand, it has been removed from the water and cleaned
  2. there is only light fouling or barnacles
  3. the cleaning is not undertaken within 50 metres of a Significant Ecological Area, and
  4. the vessel is not a barge, and
  5. the in-water cleaning of the vessel or structure is undertaken in an in-water cleaning zone, and
  6. the cleaning method does not compromise existing anti-fouling, and
  7. if any marine pest is found then a) all cleaning must cease, and b) the Regional Council's biosecurity manager and the Ministry for Primary Industries must be notified immediately.

Light fouling is defined as “A slime layer, and any extent of barnacles and small patches (up to 100mm in diameter) of visible macrofouling totalling less than five percent of the normally wetted hull and niche areas.”

To report a marine pest, please email: [email protected] and we will tell you what to do next to prevent spreading the pest.

Before you clean

If – and only if – you meet the strict requirements for in-water cleaning, there are still a number of factors to consider. Northland's marinas, wharfs and jetties have their own rules too: check first. Don't work in busy areas such as commercial wharfs and main channels. If you have a diver in the water, ensure you fly a dive flag, and have a lookout aboard to warn – and keep an eye out for – approaching vessels. If in doubt, haul out instead.

What are the penalties?

Ignorance of our rules is no defence. People illegally cleaning boat hulls risk fines of at least $750.
