NZ COVID Tracer is a Ministry of Health app that allows you to create a digital diary of places you visit by scanning the official QR codes. This will help contact tracers to quickly identify and isolate anyone who may have been exposed to COVID-19 if there is a further outbreak in New Zealand.
You can download the app in the Apple App Store or from Google Play.
Under Alert Levels 2 and 3, all businesses and services are required to display the official NZ COVID Tracer QR code posters in a prominent place at or near the main entrances to each of their premises. (This info is posted here.)
This must be done before midnight Wednesday August 19. To create your poster go here
Further details about Level 2 and 3 requirements and restrictions for businesses is available from the Government COVID-19 website here.
