This is about the bigget teeth the privacy commissioner has. Suprised to see such a heavy handed response from them given it was only 20% of the population.
Really, the NZ privacy commissioner's office is a joke. You can see this when they say things like:
> The Office of the Privacy Commissioner also encourages individuals to challenge hard why an agency needs to collect and retain their personal information.
I've talked to people who work in govt that have had full cctv surveillance at city wide (Hamilton) level Ok'd by them. Like no worries mate, they're in public so you can use casino face detection technology on them to track wherever anyone within the inner city is detected for 40 days of collection capacity.
