It's my understanding that until the NIR solution (that's out new immunisation register than they needed to build for Covid) is further progressed that we have no way yet of doing centralised digital vaccine records. We're not like Australia who has a centralised app for health records - here people just have the likes of manage my health for their local GP.

When I was a working DHB Paediatric Nurse and was first signed off to give, then register paediatric immunisations in 2014, I was appalled at the software being used. The UI was terrible. Over complicated with too many tiny boxes. It certainly came across as being designed by bureaucratic committee and not the coalface users.

I only hope this NIR solution is not based upon that system.

The Covid app Bluetooth data tends to contradict Ashley Bloomfield's comments. 1,932,281 people with Bluetooth active out of 3,103,367 registrations, 61 %.

Just had a peak at my Exposure Notifications and I have only been pinged once on 17/08/2021 at 18:22. So I was alone at home Tauranga. The only thing I can think of that triggered it was I may have, at that time, taken my wheelie bin up the driveway to the curb. Therefore if bluetooth has an approximate range of 10 meters then it was triggered by one of my neighbours.

But I also did not get an on-screen notification!

From what we can tell, that is the last time a payload was sent to your device to check. Not when it met a nearby pair of concern.

Generated keys appear to be hidden away from malicious use.

As pointed out on the main thread.
APIs are opening up to save vaccination data too.

Wonder if it's on the horizon for us.

Australia have adapted the google pay method. While there is a non google pay one opening up too using 'Passes API'

We are working on it, it is close. Dont need NIR (old) just need CIR (Covid) and will later have NIS (all vax).

Re: Bluetooth notifications, we (the tech folks) are aware of the situation and I cant comment further on it.

The NZ implementation of it went slightly off course of standard framework in favour of making people feel safe and secure/not tracked.

The default state is upload everything to a server. In our case, it must be requested of user. Then released. Then payload generated and sent out. And the device does the work instead.

A better NZ based resource once you get a basic handle on it, is the evolving PIA which discloses it for clarity to be signed off

The excuses given regarding Bluetooth are inexcusable (there are close to 2 million using it). Whilst I realise that the Bluetooth implementation has some rough edges, it’s definitely a step up AND should be leveraged aggressively. I have personally helped family members get Bluetooth exposure notifications enabled the moment the functionality was there.

I too, have only seen one exposure poll sent through (night of the level 4 lockdown).

It would be one thing if the government said that the infected didn’t have Bluetooth enabled… but if it’s just a “meh, can’t be bothered” approach, then I don’t see the point of leaving it enabled.

They have said that.

Because of the number of cases, it wasn’t necessarily a question our contact tracers were asking at the first interview because they were trying to get the most essential information. We’ve given them a nudge around that. Secondly, it seems from the demographic of most of our cases, many of them didn’t have Bluetooth turned on

I find it very unlikely that only 1 out of 511 used the Bluetooth exposure tracking stack. How can this be missed in the interviews?

Typo on my behalf, I meant NIS. NIR is the old immunisation register that is being replaced. NIS is a brand new platform being built to store all immunisation and vaccination records and overcome all the limitations of the old NIR.

For those who hadn't read it, this finally made the media today https://www.newsroom.co.nz/govt-hasnt-used-bluetooth-tracing-since-start-of-outbreak

Andrew Chen's write up that this is based on is here - https://www.mcdp.nz/2021/08/whats-wrong-with-bluetooth-tracing.html

Technical folks over the last week have noticed that the most recent Bluetooth data made available to the NZ COVID Tracer app was on 17 August – the day we found out about Case A with the delta variant and the country went into lockdown.

Oops. Guess that's us.

I'm gathering since everyone else got it on the 17th, my 22nd was likely due to the re-enablement again
(was doing some battery marathon testing and had apparently turned it off prior)

Would explain the 18th users likely being the 'blip' of BT users rising the day of/next too.

Not just geekzone, multiple sources were discussing it. I held off as long as I could before "going loud".

The time of the exposure check is basically when your phone decided to check the MOH server, so the earliest it could do this and see the new data was sometime in the afternoon of the 17th. Any date/time later than this is because it was the first time the device did the check since the 17th (hence some people seeing the 18th, some people seeing it later).

Thanks for the write up Andrew, and for taking the time to get the message across with news outlets.

Disappointing but consistent with MoH modus operandi.
