In response to the tragic events of March 15, the New Zealand Government commissioned a royal commission of inquiry into the terrorist attack to investigate all aspects of that attack. The royal commission produced recommendations to the Government to make changes across the system to protect the lives and wellbeing of those who make New Zealand their home. The royal commission highlighted the importance of regulatory stewardship and ensuring that our legislation remains fit for purpose. Recommendation 18 of the royal commission's report was for the New Zealand Government to review all legislation related to the counter-terrorism effort to ensure it is current and enables public sector agencies to operate effectively. The Counter-Terrorism Legislation Bill is the first step in implementing recommendation 18 of the royal commission's report.
