Emergencies can happen anytime, anywhere. But you can take steps to be prepared. Please check out www.getready.govt.nz to find out how, and also to learn more about the Emergency Mobile Alerts and to ensure your phone is capable pf receiving them.
In a nutshell, they are messages about emergencies. They are sent by authorised emergency agencies to capable mobile phones. The alerts keep people safe and are broadcast to all capable phones from targeted cell towers. The alerts are targeted to areas affected by serious hazards. They will only be sent when there is a serious threat to life, health or property, and, in some cases, for test purposes.
