A high-tech United States surveillance tool which sweeps up all communications without a warrant was sent to New Zealand for testing on the public, according to an espionage expert.
The tool was called ThinThread and it worked by automatically intercepting phone, email and internet information.
ThinThread was highly valued by those who created it because it could handle massive amounts of intercepted information. It then used snippets of data to automatically build a detailed picture of targets, their contacts and their habits for the spy organisation using it.
Those organisations were likely to include the Government Communications Security Bureau (GCSB) after Washington, DC-based author Tim Shorrock revealed ThinThread was sent to New Zealand for testing in 2000-2001.
