The NZSIS was established in 1956 as the New Zealand Security Service. Until then, apart from a brief period during the Second World War, national security had been handled by the Police.
Between 1956 and 1969, we existed without a legislative base.
Our first governing legislation was introduced in 1969 (the NZSIS Act). The NZSIS Act:
- Gave the NZSIS a new name (the New Zealand Security Intelligence Service)
- Recognised our existence in statute, and
- Defined our role: to protect New Zealand from threats of espionage, sabotage and subversion.
