How to stop messages from this shortcode
Reply STOP to the number 5805. Under the NZ TCF Mobile Messaging Services Code, commercial and premium senders are required to honour STOP requests within two business days.
Note: transactional notifications (delivery updates, appointment reminders, OTP codes) are generally exempt from STOP obligations — you need to unsubscribe via the service itself.
