The Government Communications Security Bureau (GCSB) is a New Zealand government agency responsible for providing intelligence and security services. Its primary role is to protect the country's communications and information systems from foreign threats, ensuring national security and the safety of sensitive data. In addition to its protective functions, the GCSB also gathers intelligence to support the government in making informed decisions on security matters. The agency works closely with other intelligence organizations, both domestically and internationally, to enhance New Zealand's overall security posture and respond effectively to emerging threats.
