Maritime security in New Zealand

The New Zealand Government has implemented measures to address maritime security. Despite its geographic isolation, New Zealand is not immune from the threat of terrorism.

Why maritime security is necessary

The world-wide escalation of acts of terrorism has highlighted the vulnerability of the global transport infrastructure. This includes ports, which are critical infrastructure for most economies, including New Zealand’s.

Ships may be the target of attacks and hijacking; and may be used as weapons, or to transport weapons and terrorists. Ports may also be a terrorist target or be the location of an attack by a ship.

New Zealand is almost entirely dependent on seaborne trade carried by foreign shipping which means that New Zealand's supply chain is particularly vulnerable to disruption.

The New Zealand Government has implemented a range of measures to address security risks in trade and travel at the border, including the Maritime Security Act. New Zealand expects all ports and vessels that operate under the International Ship and Port Security (ISPS) Code, to maintain international best practice with regard to maritime security.

The Maritime Security Act 2004

The Maritime Security Act 2004 and its associated regulations bring the requirements of the International Ship and Port Security (ISPS) Code into legislation.

The Maritime Security Act makes Maritime New Zealand responsible for ensuring that the provisions of the ISPS Code are complied with by:

  • international trading ports in New Zealand
  • commercial freight and passenger vessels visiting New Zealand.
