The NZ COVID Tracer app helps you keep track of where you’ve been. Using the app is one thing we can all do to help contact tracing go faster when a case of COVID-19 is detected, and stop the virus from spreading.
Use the NZ COVID Tracer app to:
scan QR codes to create a private digital diary of the places you visit
use Bluetooth tracing to keep an anonymised record of the people you’ve been near
register your contact details so contact tracers can get in touch if they need to
save your National Health Index (NHI) number to speed up the process if you need a test.
Scan QR codes or add a manual entry
Scan QR codes at businesses, services and events with NZ COVID Tracer to create a private digital diary of the places you visit.
If you visit the same place — at around the same time — as someone who later tests positive for COVID-19, you will receive an alert through the app with information on how to stay safe.
Scanning QR codes keeps us 1 step ahead of the virus — the more we scan the safer we’ll be.
How to scan QR codes
When you’re out and about, and you see a QR code, open your NZ COVID Tracer app.
Tap ‘Record a visit’ if it isn't already open.
Point your phone at the QR code so it fits within the target area on your screen. Your phone will vibrate and a tick will appear to show you have successfully scanned the code and the entry has been saved.
Tap on the text box if you want to add any further details such as who you were with or what you were doing.
Then tap ‘Finish’ or ‘Okay’ to close the screen. There is no need to sign out of a place with the app when you leave.
Add a manual diary entry
You can add a manual entry to your digital diary if you cannot scan a QR code. You can also view and edit your diary at any time.
Turn on Bluetooth tracing
Bluetooth tracing allows you to receive an alert if you have been near another app user who tests positive for COVID-19. It is safe, private and anonymous.
Bluetooth tracing is not intended to replace scanning QR codes. You still need to scan QR codes to keep track of where you’ve been. Bluetooth tracing helps keep track of the people we’ve been near.
How to turn Bluetooth tracing on
To turn on Bluetooth tracing:
open the app (version 3.0.0 and later) and tap on ‘Dashboard’ if it isn't already open
if Bluetooth tracing is already turned on, the dashboard will say ‘Bluetooth tracing is on’ — otherwise, it will say ‘Bluetooth tracing is off’
tap on ‘Bluetooth tracing is off’ to bring up the option to turn it on.
Once you have turned Bluetooth tracing on, it lets your phone exchange anonymous random keys with other nearby phones that also have Bluetooth tracing turned on. It’s like your phone is giving digital high-fives to other phones you are near. The Bluetooth tracing function records how close the other phone was, and for how long.
You do not have to have the app open for it to work.
If you or another app user in your community tests positive for COVID-19, a Bluetooth alert can be sent to quickly notify any other app users who have been in close contact. This alert will advise you on what to do to keep yourself and your whānau safe.
Watch our Bluetooth tracing video on this page to see how it works.
Your privacy is protected
Bluetooth tracing is entirely anonymous. No personal or identifying information is exchanged between phones, and Bluetooth tracing cannot be used to track your movements.
This means no one will ever see who you’ve been near, or when or where you were near them, even if you test positive for COVID-19.
If you need to visit a COVID-19 testing station, it's helpful to have your National Health Index (NHI) number with you, as this can help speed up the process. An NHI number is a unique identifier that is assigned to every person who uses health and disability support services in New Zealand.
Save your NHI number in NZ COVID Tracer by going to the ‘My data’ screen and tapping on ‘My NHI details’.
