Help with the NZ COVID Tracer app

Last updated: 19 April 2021

Known issues

You can download NZ COVID Tracer from anywhere in the world, but it may be difficult to find on the Google Play Store if you are based in another country. Download NZ COVID Tracer for Android

Some Samsung users have reported issues with their rear camera not focusing, which is impacting their ability to scan easily. Please don’t delete the app as this will delete your digital diary. Please consider adding a manual entry instead.

Some iPhone users are reporting they can’t add manual diary entries. A fix will be available in the next release, but in the meantime, this can be resolved by turning off the Reduce Motion and Prefer Cross-Fade Transitions function in the Accessibility settings. To check this and resolve on your iPhone, 1. Open Accessibility settings, 2. Open Motion settings, 3. See Reduce Motion turned on, 4. Turn off Prefer Cross-Fade Transitions and Reduce Motion.

Latest version

The latest version of NZ COVID Tracer (version 5.0.0) was released on 24 May. This release includes a number of new features which make the app faster, easier to use and more useful.

  • Some iPhone users may have an issue turning on Bluetooth tracing in the app. If this happens, please open your phone’s 'Settings' and find the 'Exposure Notifications' item. Turn on 'Exposure Notifications' and select New Zealand as your region.

System requirements

In the current release of NZ COVID Tracer, Android devices need to have Android 6.0 or later, while Apple devices need iOS 10 or later. 

If you have an older operating system, you may be able to update it to a more recent version. For information on how to update your phone’s operating system, please refer to the guidance for Android users or Apple users as applicable.

Updating the app

If your phone is set to automatic updates, NZ COVID tracer will update automatically within a few days of an update being released.

You can also manually update NZ COVID Tracer:

  • For iPhone users, open the App Store and tap ‘Today’ at the bottom of the screen. Then tap your profile icon to bring up your Account. Scroll down until you see NZ COVID Tracer and then tap ‘Update’.
  • For Android users, open the Play Store and tap on the three horizonal lines at the top-left of the screen to open the sidebar. Open ‘My apps & games’ and select the ‘Updates’ tab. Then scroll down until you see NZ COVID Tracer and tap ‘Update’.

Transferring a digital diary to another device

You can transfer your digital diary from one iPhone to another. Make sure you follow the steps below before you reset or factory restore your old phone.

Unfortunately, this is not currently possible on Android devices as data migration apps do not guarantee the transfer of your digital diary.


  • We cannot guarantee this process will work for all phones, so we highly recommend you take screenshots of your digital diary before you start the back-up process. This will ensure you have a record of your scans if the process is unsuccessful.
  • Make sure the NZ COVID Tracer app is selected as one of the apps you want to restore on your new phone. Re-installing the app from the App Store will instead delete your data. 
  • You cannot transfer your digital diary if you have lost your phone and did not have it backed up.

Back up for iPhone users:

Data usage

The app uses a small amount of data when you register your contact information, when your phone checks for contact alerts, when you enable Bluetooth tracing, and when anonymised analytic information is sent to the Ministry for reporting purposes.

However, your phone doesn’t need to be connected to data to scan QR codes, use Bluetooth tracing, or when you add manual entries to your digital diary.

If you are concerned about data usage, you may want to wait until you are connected to Wi-Fi before you download or update the app. Once you’ve downloaded the app, the ongoing data usage is minimal.

Problem scanning

If you have any problems scanning QR codes, please email [email protected]

Please include the following information:

  • your phone’s make and model
  • the operating system you’re running
  • a description of the issue you are experiencing.

If you can’t use the app

It’s important to keep track of where you’ve been and who you’ve been with in any way that works for you. This makes contact tracing faster in the event that you contract COVID-19.
