The New Zealand spy agency, the Government Communications Security Bureau (GCSB), worked in 2012 and 2013 to implement a mass metadata surveillance system even as top government officials publicly insisted no such program was being planned and would not be legally permitted.
Documents provided by NSA whistleblower Edward Snowden show that the government worked in secret to exploit a new internet surveillance law enacted in the wake of revelations of illegal domestic spying to initiate a new metadata collection program that appeared designed to collect information about the communications of New Zealanders.
