Terrorism Suppression Act 2002 is New Zealand counter-terrorism legislation passed under the Clark-led Labour government . Enacted following the September 11 attacks , the Act was designed to better address contemporary terrorism issues , both domestically and abroad . Until May 2019 , the Act had not been formally used in a prosecution ; however there were several failed attempts by the Crown to do so . Many individuals and organisations have however been designated as " Terrorist entities " under the Act 's provisions , in line with UN Security Council designations . The Act was amended in 2007 . In May 2019 , a charge of engaging in a terrorist act was laid against the alleged shooter in the Christchurch mosque attacks , under section 6A of the Act
