New Zealand spies were cogs in the American "war on terror" machine, intercepting radio and cellphone calls and mapping targets for bombers and infantry, according to Nicky Hager's new book.
Other People's Wars contains details about New Zealand intelligence agents who were trained in the United States and sent to Afghanistan to monitor suspected insurgents.
Meanwhile, resources in New Zealand were dramatically boosted to increase spying and share intelligence with the US, Britain, Canada, and Australia - at the expense of focusing on issues of national interest.
A 2007 US Embassy cable suggested Helen Clark was aware of the focus; US diplomat David Keegan wrote that she was "willing to address targets of marginal benefit to New Zealand that could do her political harm if made public".
Hager's book names intelligence specialists Helen Murphy, Darby Allen and Steve Mahoney (pseudonym) as extra manpower for US intelligence.
