In 1987, Gerald Hensley, Chair of the NZIC, stated that the State Services Commission became attracted to the concept of "comprehensive security", taking into account not only human-made threats such as terrorism but also natural hazards. This was also a response to the severing of intelligence-sharing arrangements New Zealand had with the United States in 1985 over nuclear policy. Following the attempted hijacking of an Air New Zealand flight and the bombing of the "Rainbow Warrior" in 1985, Parliament enacted the International Terrorism (Emergency Powers) Act 1987. The Act gave censorship powers to the government around matters of national security and terrorism. This was a significant departure from New Zealand's previous conformance to international norms and laws.
