The history of New Zealand's intelligence agencies and those it has spied on have been laid bare in a book by Auckland-based journalist, author, and historian Graeme Hunt.

Spies And Revolutionaries – A History of New Zealand Subversion details how several prominent New Zealanders, all of whom are dead, spied for the former Soviet Union during the Cold War. Accusations and suspicions are laid bare before files and information that has never before been made public. This book will clearly recharge debate as to whether Dr Bill Sutch, diplomat Paddy Costello, and public servant Ian Milner were spies acting against New Zealand's national interest.
