Of course, New Zealand, as the previous speaker, Christopher Luxon, said, has been something of an outlier on this. In fact, in November 1973 the International Maritime Organisation (IMO) adopted the International Convention for the Prevention of Pollution from Ships (MARPOL), which remains today the main international convention covering preventing the pollution of maritime environments by ships from operation or accidental causes. Obviously, this is a piece of legislation that now underlies efforts to do what the world is now increasingly seeking to do: reduce pollution. New Zealand joined MARPOL in 1998 and is a party to four of the six annexes of that treaty.
