This page provides information on the International Convention for the Prevention of Pollution from Ships, 1973 (MARPOL), which New Zealand acceded to on 25 September 1998.
New Zealand’s coastal and marine resources are at risk from land-based sources of marine pollution, ocean dumping and oil spills. Several of our international obligations regulate activities with potential for these environmental effects. These include the 1973 Convention on the Prevention of Marine Pollution by Dumping of Wastes and the 1971 Convention on the Prevention of Marine Pollution by Dumping of Wastes and Other Matter (London Dumping Convention).
MARPOL aims to eliminate pollution of the sea by oil and other toxic substances which might be discharged during normal operations, or released accidentally as a result of collisions or stranding of ships. It is primarily implemented through the Exclusive Economic Zone and Continental Shelf (Environmental Effects) Act 2012 and Maritime Transport Act 1994 [NZ Legislation website].
