Electronic eavesdropping systems, computer programmes that automatically index and search captured communications, and databases where details of a whole region's communications are stored: these are all standardised parts of the global surveillance system run by the US National Security Agency (NSA).
Some people would be surprised to learn we have spy bases like these in New Zealand. One of the portfolios I picked up as a new Green MP is security and intelligence.
The role took me down to the Waihopai spy base last month, and I got to speak at the annual protests at the gates of the facility, near Blenheim. The giant white spy domes, which look like something out of a sci-fi movie, are a lot more foreboding and ominous in real life.
The spy base is operated by New Zealand's Government Communications Security Bureau (GCSB) in the interests of the foreign powers grouped together in the super-secret UKUSA Agreement.
New Zealand is a member of the UKUSA Agreement, a multilateral agreement for signals intelligence (SIGINT) co-operation. This international alliance is also referred to as the Five Eyes, and Waihopai functions as a cog in that spying machine. It is the alliance's main eye on the South Pacific region.
