The Government Communications Security Bureau (GCSB) (Māori: Te Tira Tiaki) is the public-service department of New Zealand charged with promoting New Zealand's national security by collecting and analysing information of an intelligence nature. The GCSB is considered to be New Zealand's most powerful intelligence agency, and has been alleged to have conducted more espionage and data collection than the country's primary intelligence agency, the less funded NZSIS. This has at times proven controversial, although the GCSB does not have the baggage of criticism attached to it for a perceived failure to be effective like the NZSIS does. The GCSB is considered an equivalent of GCHQ in the United Kingdom or the NSA in the United States. More information...
