ony Fullman is a middle-aged former tax man and a pro-democracy activist. But four years ago, a botched operation launched by New Zealand spies meant he suddenly found himself deemed a potential terrorist — his passport was revoked, his home was raided, and he was placed on a top-secret National Security Agency surveillance list.

The extraordinary covert operation, revealed Sunday by Television New Zealand in collaboration with The Intercept, was launched in 2012 after New Zealand authorities believed they had identified a group planning to violently overthrow Fiji’s military regime.

As part of the spy mission, the NSA used its powerful global surveillance apparatus to intercept the emails and Facebook chats of people associated with a Fijian “thumbs up for democracy” campaign. The agency then passed the messages to its New Zealand counterpart, Government Communications Security Bureau, or GCSB.

One of the main targets was Fullman, a New Zealand citizen, whose communications were monitored by the NSA after New Zealand authorities, citing secret evidence, accused him of planning an “an act of terrorism” overseas.

But it turned out that the claims were baseless — Fullman, then 47, was not involved in any violent plot. He was a long-time public servant and peaceful pro-democracy activist who, like the New Zealand and Australian governments at that time, was opposed to Fiji’s authoritarian military ruler Frank Bainimarama.

Details about the surveillance are contained in documents obtained by The Intercept from NSA whistleblower Edward Snowden. More than 190 pages of top-secret NSA logs of intercepted communications dated between May and August 2012 show that the agency used the controversial internet surveillance system PRISM to eavesdrop on Fullman and other Fiji pro-democracy advocates’ Gmail and Facebook messages. Fullman is the first person in the world to be publicly identified as a confirmed PRISM target.

At the time of the spying, New Zealand’s surveillance agency was not permitted to monitor New Zealand citizens. Despite this, it worked with the NSA to eavesdrop on Fullman’s communications, which suggests he is one of 88 unnamed New Zealanders who were spied on between 2003 and 2012 in operations that may have been illegal, as revealed in an explosive 2013 New Zealand government report.

In response to questions for this story, the NSA declined to address the Fullman case directly. A spokesperson for the agency, Michael Halbig, said in a statement to The Intercept that it “works with a number of partners in meeting its foreign-intelligence mission goals, and those operations comply with U.S. law and with the applicable laws under which those partners operate.”

Antony Byers, a spokesperson for New Zealand’s intelligence agencies, said he would not comment “on matters that may or may not be operational.” The country’s spy agencies “operate within the law,” Byers said, https://theintercept.com/2016/08/14/nsa-gcsb-prism-surveillance-fullman-fiji/
