To download the Covid Tracer app, people should visit the Apple Store or Google Play on their device.
When people visit a business or premises, a QR code poster should be on display. The app will provide instructions on how to use the QR code to check-in.
If app users have been put at risk of exposure to Covid-19, health officials will ensure they receive a notification on their device to let them know of the next steps and whether or not they need to be tested.
If people need help with the app they can call 0800 800 606, or email help@covidtracer.min.health.nz
For businesses, information on downloading QR code posters is on the Unite Against Covid-19 website at covid-19.govt.nz
If people do not have access to a device that is capable of downloading the app, they are asked to track their movements manually.
It is recommended that you keep track of the 3 Ws: where you went, when you went there and who you were with.
You can track this by keeping a diary or list, or taking time-stamped photos of where
you've been.
