Earlier quoted context omitted.
Is there anything you guys in New Zealand haven't done better during this pandemic? :-)
"Better" is certainly a point of view here. Having to tell the government all of your whereabouts when you already live on an Island with no spreading is an overreach, IMO.
For most Kiwis this means a bunch of QR code data is stored on their phone and, months or years from now when the emergency is over (depending on how incompetent other countries are) that data is deleted. There is no NZ department of health MySQL database full of geo data of every New Zealand citizen and never will be.
If you're a case (remembering that New Zealand has elimination, so rather than cases being millions of people as in the US for example, they're very rare) then you can choose to help the contact tracers by giving them your data and in that case they do get all the data because you gave it to them. Because New Zealand has elimination contact tracing is something done by a handful of experts.
I would guess that like most countries New Zealand's contact tracing experts worked previously with sexually transmitted infections - so they already understand the sensitivity of this work. COVID-19 is actually less awkward, because at least you don't have to admit to fucking somebody you claim you're not sexually attracted to, just that you were in the same room as them for a period of time.
But of course none of what I wrote above matters much because those are merely facts, and for so many Americans mere facts can't oppose a Truth they have become certain of despite all evidence to the contrary. Not that Mother Nature gives a damn whether you believe her.
