As a "child of the '60s" - I'm amazed at the complacency shown here (and elsewhere) about constant round the clock surveillance by the state (or in this case by an agent of the state working for the state).
The "law and order"argument is all good and fine, but crime was/is falling anyway, and despite hysteria (media fueled), NZ (even Auckland) is a very safe place to live by international standards.
Having lived through a decade of hysteria about the "Red Threat" - much of which was based upon criticism of how those (totalitarian) regimes surveilled their citizens - compared with "western freedom" - it does surprise me how positively this is being received.
