Quite simply, this bill will allow New Zealand's existing laws against serious criminal offending to be enforced in international waters where New Zealand has extra-territorial jurisdiction. This includes offences that take place on a New Zealand - flagged vessel in international waters, offences that take place on board a foreign-flagged or a stateless vessel in international waters but where New Zealand has extra-territorial jurisdiction, and in situations where a person is suspected of committing an offence against New Zealand law and is located on a foreign, New Zealand, or stateless vessel.
