third speed bump came just last week, when NZTA deferred using number-plate spotting cameras on a highway (see below).

The march is mostly one way, though – including to the bank for the tech-makers and marketers, who are known to protest at the media calling their products “surveillance”.

Such sensitivities have not put off governments spending on public-private hybrid systems.

New Zealand has its own, used by powerful state agencies, the police and Immigration.

Many of the camera systems could run facial recognition (FR). Sometimes you are just asked to trust the FR function is not switched on.
