The disposal of waste in New Zealand’s waters is managed under both domestic and international legislation. Read below about the regulations that apply, including for burials and disposal of vessels at sea.

Waste disposal beyond the 12 nautical mile limit

Marine dumping permit
Burials at sea
National policy on the sea disposal of waste
The most common types of material that are disposed of are dredge spoil from ports and harbours, and decommissioned vessels.
Waste disposal within the 12 nautical mile limit of New Zealand's territorial waters is regulated by regional councils under the Resource Management Act 1991. It is the Marine Pollution Regulations 1998 made under the Resource Management Act that specifically applies here.

Waste disposal beyond the 12 nautical mile limit in New Zealand's exclusive economic zone is administered by Maritime New Zealand under the Maritime Transport Act 1994. The Act authorises the Director of Maritime New Zealand to issue a permit for the disposal of waste or other matter:

Five locations are identified as preferred areas for marine disposal beyond the 12 nautical mile limit in New Zealand's exclusive economic zone (within the jurisdiction of Maritime New Zealand). These locations are existing explosives dumping grounds.
Applications may be considered for other areas in accordance with Marine Protection Rule Part 180 and the National Policy on the Sea Disposal of Waste, but any such proposals will require a greater level of environmental impact assessment and clear justification why existing sites cannot be used.

Dumping standards for both jurisdictions (see points 1 and 2 above) in New Zealand are derived from the 1996 Protocol, to which New Zealand is a party. The 1996 Protocol refers to the International Convention on the Prevention of Marine Pollution by Dumping of Wastes or Other Matter, 1972. It is also known as the London Convention.
The global aim of the 1996 Protocol is to:
“Protect and preserve the marine environment from all sources of pollution and take effective measures (according to scientific, technical and economic capabilities), to prevent, reduce and where practicable eliminate pollution caused by dumping or incineration at sea of wastes or other matter.”
A key principle of the 1996 Protocol is the consideration of avoidance, re-use and minimisation of waste sources in order to minimise the amount of material that is required to be dumped at sea. This principle is a well-established requirement of the New Zealand domestic legislation.
The 1996 Protocol embodies the precautionary approach to dumping waste at sea. Rather than setting out the wastes that are NOT allowed to be dumped, the 1996 Protocol defines categories of wastes that MAY be considered for dumping at sea, provided the applicant can demonstrate that no adverse effects will result. All other categories are prohibited from disposal at sea.

The following wastes or other matter may be considered for dumping, provided that any material capable of creating floating debris or otherwise contributing to pollution of the marine environment has been removed to the maximum extent. Also provided that the material dumped poses no serious obstacle to fishing or navigation.
Wastes or other matter may be considered for dumping:
Applicants are required to demonstrate that no pollutants are on board vessels intended for disposal at sea and that no other viable disposal options are possible.
In addition, applicants needing to tow a vessel to a disposal location must demonstrate that it is 'fit for tow'. This will ordinarily involve the use of an independent surveyor of ships and provision of a passage plan.

Applications for burial at sea will be considered at the five existing Exclusive Economic Zone marine disposal sites. Please contact Maritime New Zealand for more information.
A dumping permit is required to dump waste in New Zealand’s waters, including for the disposal of vessels and sea and burial at sea.
There are no fixed fees associated with applications for dumping permits. An hourly rate however is applied for staff involved in accordance with the Shipping (Charges) Regulations 2000. Usually this will involve scientific staff or staff at managerial levels, charged at a rate of $141 per hour inclusive of GST.
