Sign in

The first time you open NZ COVID Tracer, you’ll be asked to enter your email address and create a password. You’ll then receive an email with a 6-digit code that will allow you to complete the sign in process.


Register your details

After signing in you can go to the Dashboard to:

  • register your details
  • let us know where you’re staying
  • invite friends and whānau to download the app
  • register your interest in features that will be added to the app in future updates.

Create your digital diary

Once you’ve signed in you can start using NZ COVID Tracer to create a digital diary of the locations you visit. 

Select the ‘Scan’ option and point your camera at any Ministry of Health COVID-19 QR code poster so the code fits within the target area on the display of your phone. 

Your phone will vibrate and a green tick will show up on the display when the QR code has been scanned successfully. 

You can view your digital diary at any time by tapping the icon on the top-left of the ‘Scan’ screen or by opening the 'Check-in history' on the 'My profile' screen.

Sign up for contact alerts

You can make sure you’re signed up for contact alerts by visiting the NZ COVID Tracer dashboard and checking the ‘Receive contact alerts’ tile. 

  • If you are an Android user, contact alerts will be enabled by default. 
  • iPhone users may have to enable contact alerts.

Once you are signed up for contact alerts, NZ COVID Tracer will let you know if you have checked into a location at the same time as a confirmed or probable case of COVID-19, so you can be on the watch for any symptoms and take appropriate steps to protect your friends and whānau.

Contact alerts work through ‘push notifications’ to your phone. Notifications will include information about the locations and timeframes where people may have been exposed to COVID-19. If there is a match with the information stored in your digital diary, you’ll receive a contact alert. This does not involve transmitting any location information from your phone to the Ministry of Health.


Share your digital diary with contact tracers

If you are identified as a confirmed or probable case of COVID-19, a contact tracer will get in touch to provide advice on self-isolation and to check on your health and wellbeing.

During the phone call, the contact tracer will also ask you for information about the places you’ve been and the people you’ve seen.  To help with this, you can open your digital diary by going to the ‘My profile’ screen and bringing up your ‘Check-in history’.

The contact tracer may also ask you to share your digital diary with the Ministry of Health. You can do this by selecting the ‘Upload check-in history’ option within the ‘My profile’ screen. You’ll be prompted to enter your personal information (if you haven’t previously entered it into NZ COVID Tracer).The contact tracer will then provide you with a verification code which will allow you to transmit your digital diary to us.

Sharing your digital diary will help contact tracers identify whether any of your friends, whānau or community members may also have been exposed to COVID-19, so we can respond quickly and stop any further spread of the virus in New Zealand.
