The 5th Eye documentary
This film is about the Waihopai 3 who broke into the Spybase and deflated one of the radomes. But it is also about New Zealand's role in Afghanistan, focusing on reporting by journalist Jon Stephenson, and the surveillance and harassment he received unearthing details about secret NZSAS raids that killed civilians.
