TVNZ+ notifications are managed in the settings on your device.  Navigate to Settings > Notifications > TVNZ to turn off push notifications.

TVNZ+ can send you push notifications to your iOS or Android devices when new episodes of favourite shows are available for you to view.

Push notifications are alerts or updates that appear automatically on your device, depending on the settings you have in place on your phone.

Simply click the My List button to add a show to your favourites and you will be notified when a new episode is made available on your chosen mobile device.

Double check that you have enabled notifications in your TVNZ+ app.
