The Government Communications Security Bureau (GCSB) is a public service department with its head office in Pipitea St in Wellington. It also has two communications collection or interception stations: a high frequency radio interception and direction-finding station at Tangimoana, near Palmerston North, and a satellite communications interception station at Waihopai, near Blenheim.
The National Cyber Security Centre (NCSC) has been located within the GCSB since 2011. The NCSC provides enhanced services and advice to government agencies and critical infrastructure providers to help them to defend against cyber-borne threats.
The Director of the GCSB since January 2012 is Ian Fletcher. The Director reports directly to the Minister responsible for the GCSB, traditionally the Prime Minister.
GCSB has approximately 300 staff in a wide range of disciplines, including foreign language experts, communications and cryptography specialists, engineers, technicians, and support staff. GCSB’s appropriation is $63 million for the 2012/2013 year.
