But more importantly, none of it legally matters. Because the GCSB Act doesn't talk about "surveillance" or "collection" - it talks about "interception". What's "interception"?
intercept includes hear, listen to, record, monitor, acquire, or receive a communication, or acquire its substance, meaning, or sense
Its a pretty expansive definition, which covers not just the traditional ideas of someone sitting there with a pair of headphones while you're on the phone, but also recording it for later use, acquiring it from a foreign "partner", or even just being given a summary. They don't have to look at it - simply recording or acquiring it is enough. And it applies to any communication whatsoever, whether phone calls or internet or Morse code.
It is clear from what we've seen so far and what has been admitted that there is mass-interception across the Pacific. Because of the method - "full-take" - that mass-interception necessarily includes the private communications of New Zealand persons. The scale of that interception seems to be well beyond a level where it could be considered "incidental", and to piss on the legal requirement to minimise impacts on third parties. John Key was the Minister in charge of the GCSB at the time, and he still holds overall responsibility through his national security portfolio. The buck for this stops with him, and its time we held him accountable for what the spies have done under his watch.
