Allow the phone to deliver notifications
The TVNZ help places the basic permission in the device settings. On iPhone or iPad, open Settings, TVNZ+, Notifications and change Allow Notifications. On Android, use Settings, Apps or App management, TVNZ+ and Notifications. This system permission is the first layer; selecting an alert category inside the app does not establish that the operating system permits its delivery.
Choose episode and marketing pushes separately
Once device notifications are enabled, open the TVNZ+ app’s Settings and Notifications. New episodes and Marketing have independent switches, so a viewer can retain release alerts for saved shows while changing promotional pushes. TVNZ says this push feature is for mobile and tablet apps, rather than a notification service on smart televisions or computers.
Change promotional email through its own route
For email, sign in on a web or mobile browser, open the profile, Account and Preferences, and change the option allowing TVNZ to contact you about new or interesting things. A marketing email also has an unsubscribe link for that email type. This email preference is separate from the phone’s notification permission, so changing one should not be assumed to configure the other.
Expect essential account messages to continue
TVNZ expressly retains emailed login codes and account or payment confirmations regardless of marketing choice. These are needed for the account to operate. Its help also says marketing emails go to the primary account-holder address; secondary profiles have no separate email addresses. If the purpose is reducing promotions, adjust the relevant category rather than expecting an unsubscribe action to disable necessary sign-in messages.
