Does the new NZ COVID app pass muster?

As contact tracing apps become a feature of life during the Covid pandemic - just how many are we going to have to put up with? The government's NZ COVID Tracer hit Apple's App Store and Google Play stores on Tuesday night, and by the time the Director General of Health Ashley Bloomfield did his media appearance at 1pm yesterday 92,000 people had downloaded it. It's an app of two halves: your personal information will be registered with the Ministry of Health, while your phone will store location information collected via QR code scanning. But you'll still have to use various registers provided by businesses. Joining Lynn to talk about the app is computer systems engineer Andrew Chen, a research fellow with Koi Tu: The Centre for Informed Futures at the University of Auckland.
