Maritime Rule Part 24A
Maritime Rule Part 24A sets out the responsibilities of seafarers, ship owners, shippers, consolidators and packers in respect of dangerous goods to be carried by sea. This rule makes mandatory in New Zealand, the packaging and stowage requirements of the International Maritime Dangerous Goods (IMDG) Code.
The transportation, storage, importation, manufacture and use of explosives are now regulated under the Hazardous Substances and New Organisms (HSNO) Act 1996. This Act is administered by the Environmental Risk Management Authority (ERMA).

Oil spills – take immediate steps
Any oil discharge or accidental spill of oil into the water must be reported immediately.
Vessel operators should make all reasonable attempts to stop the discharge and prevent oil reaching the marine environment. For example by plugging scuppers and collecting any oil from the deck. Where possible oil should be contained and recovered from the water.
Permitted versus illegal discharges and spills
While vessels are permitted to dispose of some types of waste at sea, there are strict requirements relating to the type of waste and the distance from land where the disposal may take place.
All pollution sightings should be reported. The appropriate authorities can then determine if the discharge or waste disposal is authorised.
New Zealand’s marine environment protection legislation, regulations and conventions place rules and limits on the discharge of harmful substances into the sea, from for example:
- oil, including waste oil, fuel oil, sludge, lube oil and additives
- garbage including food, paper, bottles and plastics.
Chemicals and their risk to the Marine Environment
A wide variety of chemicals and other noxious liquid substances are shipped to, from and around New Zealand. Release of these chemicals into the marine environment could have serious effects.
Hazardous substances include foodstuffs like vegetable oils, by-products like tallow, and synthetic chemical raw materials (feedstocks) used for industrial processes.
Noxious liquid substances are traded in significant quantities worldwide, and the conditions of their carriage are governed by MARPOL 73/78 (the International Convention on Prevention of Pollution from Ships).
Within the 12 mile limit, there are no permitted discharges of noxious liquid substances from ships carrying these substances in bulk as cargo.
The Resource Management Act 1991 regulations cover discharges in the coastal marine area. The marine protection rules cover:
- the type of ship that must be used to carry particular substances
- permitted volumes of cargo residue that may be left in a tank before being washed (or ballasted)
- the residues permitted to be discharged into the sea
- shipboard records and emergency preparedness requirements.
