Five Nations is a relatively new immigration meeting established in May 2002 by the CEOs of immigration from United States, United Kingdom, Canada and Australia. New Zealand was subsequently invited to join the group. The main aims are to share technical information, embark on joint operational initiatives and co-operation on Advanced Passenger Information systems and common standards. It is a useful forum for sharing information about unilateral API systems with like-minded countries, and ensures compatibility of systems in the future.
