Surely just installing an app voluntarily would get enough tracing to be effective?

As a kiwi who has spent half my life living in different countries, I can say trust in the government here, while not universal, is higher than anywhere else I've been. I think most people would do it

"Without fast case isolation after restrictions ease, modelling shows that the virus could spread exponentially and ultimately kill 100,000 Kiwis." The left out the word "unreasonable". "Unresaonable modelling shows..." See the Tailrisk analysis: http://www.tailrisk.co.nz/documents/Corona.pdf

Yeah but the Tailrisk guy is not an epidemiologist, he's out of treasury and naturally has is more economy focused outlook.

One person's "unreasonable" can be another's "sensible caution"

The big problem with all radio based contact tracing solutions is the receiver. Receivers use at a minimum several mW of power. A typical Bluetooth low energy receiver will use about 50mW so will drain a coin cell battery in a day. Bluetooth low energy saves energy by transmitting for very short periods of time so transmit power is low but receiver power can be high. Even asking most consumers to leave their phone's…

Your phone's Bluetooth scanning IS always on if it's an iPhone or Android. Always. By default.

"The only central register of card IDs would be held by the Government and isolated from other Government databases, so it could not be used for anything other than Covid-19 contact tracing." What does "could not" mean, anyway?

Same argument currently being brought by the German PEPP-PT project. I really don't get why they push for these centralised solutions when clearly defined decentralised models exist.

You literally have a government official who's title is "Chief Censor". I have no doubt that trust in the government is high. Thats what government censorship is for.

Kiwi here, I belive this is either snake oil or a conceptual idea rather than a product. The media are touting it as credit card sized device, but with a battery it would need to be much thicker. Here in lockdown we are allowed to go for a walk or cycle. Potentially this card could register thousands of contacts.

I have wondered why Tile here in the U.S. doesn’t do exactly this. Tile “cards” are about the thickness of a credit card. I have one in my wallet so I can “beep” my wallet when I can’t find it.

The power needs must be miniscule, I assume.

Anyway I think its technical feasability is established vis a vis powering electronics in that form factor.

And gathering a lot of recorded contacts is exactly what the goal is, so that’s not a bad thing.

Agree. compared to the shit-storms politicians are creating in other countries I'm sort of proud of the way our government acted so decisively and unilaterally, and I generally get the feeling they are acting for the good of the people not themselves.

I can already see the cracks appearing as some idiots try to score points or promote their own agendas and the media are happy to give them air time, the "covidcard" or phone tracing app will open another one of those cracks even though like you say the majority would conform
