More about the book

This book describes the secret activities of the many people and places involved with listening to and decoding the enemy's signals during two world wars. Known as SIGINT for Signals Intelligence, this is New Zealand's unseen contribution.
The authors have unearthed and brought to light much of what has been lost or hidden during these years, including New Zealand's significant contribution to the nerve-wracking scramble to locate the Scharnhorst battle cruiser in the northern Atlantic Ocean in 1943. Because secrecy was paramount, their station locations and personnel, their triumphs and failures, were never reported. And this secrecy continues to the present day, having all but sunk out of sight.
As Dr Warren Tucker, the Director of the Security Intelligence Service, comments in his foreword:
"I am delighted that this book now puts firmly into the public arena a record of New Zealand's small but important SIGINT contribution to the wartime Allied effort."
This book is a must for all with an interest in intelligence matters, as well as those who enjoy insider histories of the war."
