The discharge of oil, fuel and oily waste poses a threat to the marine environment. There are a number of regulations in place to prevent oil pollution.
Discharge of oil is prohibited and all possible measures should be used to prevent accidental spills.
New Zealand is a party to Annex I of MARPOL 73/78, the International Convention on Prevention of Pollution from Ships. Annex I includes regulations for the prevention of pollution by oil.
Oil and petroleum products must not be discharged anywhere within New Zealand’s territorial waters or within the Exclusive Economic Zone. The only exception to this is where the discharge has the purpose of avoiding, remedying or mitigating an oil spill or for saving life at sea.
Chemical oil dispersants may not be used anywhere within New Zealand’s territorial waters or Exclusive Economic Zone without prior approval from Maritime New Zealand.
Oily wastes such as bilge water and machinery waste can only be discharged if the dissolved hydrocarbon content is less than 15mg of oil per litre of water, and the ship is en-route and the oil is not being carried as cargo. Oily rags and other oiled solid waste must not be discharged anywhere within New Zealand’s territorial waters or Exclusive Economic Zone.
Facilities for the reception of oiled solid and liquid waste are available at all New Zealand ports.

The land disposal of these wastes is regulated under the Resource Management Act (RMA).

In the event of an oil spill, vessel operators should make all reasonable attempts to stop the discharge and prevent oil reaching the marine environment. For example by blocking scuppers and collecting any oil from the deck. Where possible oil should be contained and recovered from the water.
Regional councils and Maritime New Zealand have spill response expertise and equipment to activate once a spill has been reported.
