Secret History - Steven Loveridge - Bog

"In 1900, a handful of New Zealand police detectives watched out for spies, seditionists and others who might pose a threat to state and society. The Police Force remained the primary instrument of such human intelligence in New Zealand until 1956 when, a decade into the Cold War, a dedicated Security Service was created. Over the same period, New Zealand's role within signals intelligence networks evolved from the Imperial Wireless Chain to the UKUSA intelligence alliance (now known as Five Eyes)"--Publisher information.
