For the purposes of its signals intelligence activities, the GCSB maintains two "listening stations": a satellite communications interception station at GCSB Waihopai near Blenheim and a radio communications interception station at GCSB Tangimoana near Palmerston North. On 16 March 2015, the former National Security Agency contractor and whistleblower Edward Snowden disclosed that New Zealand's GCSB agency had a secret listening post, codenamed "Caprica", at the New Zealand High Commission in Honiara, the capital of the Solomon Islands. The "Caprica" outpost was reportedly modeled after the American National Security Agency's Stateroom outposts at selected United States Embassies across the world.
