The Government Communications Security Bureau (GCSB) is a public service agency.
Our mission is to provide our customers with intelligence advantage and cyber resilience to successfully navigate an unpredictable world.
We are New Zealand’s lead organisation for Signals Intelligence (SIGINT), meaning we specialise in intelligence derived from electronic communications.
We also provide cyber security and resilience for organisations of national significance.
We contribute to:
- The protection of New Zealand’s national security
- The international relations and wellbeing of New Zealand
- The economic well-being of New Zealand.
Under the Intelligence and Security Act 2017 we have four core functions:
- Intelligence collection and analysis
- Protective security advice and assistance, including information assurance and cyber security activities
- Co-operation with other public authorities to facilitate their functions, and
- Co-operation with other entities to respond to imminent threat.
We have offices in three locations; Wellington, Auckland and Waihopai, near Blenheim. We also have a high frequency radio interception and direction-finding station in Tangimoana, near Palmerston North.
