The Intelligence and Security Act 2017 is a New Zealand law that enhances the powers of intelligence and security agencies. It aims to improve national security by allowing agencies like the Government Communications Security Bureau (GCSB) and the New Zealand Security Intelligence Service (NZSIS) to better respond to threats, including terrorism and cyberattacks. The Act also establishes clearer oversight and accountability measures for these agencies. It ensures that their activities are conducted within legal frameworks, protecting citizens' rights while enabling effective intelligence operations. This balance is crucial for maintaining public trust in national security efforts.
