New Zealanders should prepare for a nationwide test of the emergency mobile alert system this Sunday, June 14. Between 6 p.m. and 7 p.m., the National Emergency Management Agency (NEMA) will broadcast a test alert to all capable, SIM-connected devices. The exercise is designed to ensure the system functions correctly and to familiarize the public with the signal before a real emergency occurs.
How the alert system functions
The emergency mobile alert system operates by broadcasting to cellphone towers rather than targeting individual devices, according to NEMA. This allows authorized staff to trigger alerts for specific geographic areas, down to a single tower if necessary. While the alert is designed to override silent mode on most phones, it will not reach devices placed in flight mode. NEMA director John Price has previously stated that because citizens cannot opt out of an emergency, they cannot opt out of the system’s alerts.
Who will receive the alert
Not every mobile device will sound an alarm. Reception depends on a handset’s make, model, age, and software version. Historically, roughly nine out of ten phones receive the message during national tests. However, coverage is likely to improve over time, as all new phones sold in New Zealand are now required to support the emergency mobile alert system. As older devices are retired and replaced with newer models, the percentage of successful deliveries is expected to rise.
Recommended precautions and usage
NEMA advises individuals who may be affected by sudden loud noises—or those who keep a hidden phone for personal safety—to switch off their SIM-connected devices or enable flight mode during the 6 p.m. to 7 p.m. window. For those who receive the alert, Price suggests pressing the volume button on the side of the phone to silence the alarm while keeping the notification visible on the screen. If dismissed, the alert can typically be found in the notification center on iPhones or within emergency alert settings on Samsung devices.
Context of the test
Sunday’s event marks the ninth annual test of the system. It follows a year of significant activity; according to NEMA, 66 alerts were sent in the past 12 months, making Sunday’s test the 67th activation. The system is managed by approximately 200 authorized users across various agencies, including Police, Fire and Emergency New Zealand, the Ministry of Health, the Ministry for Primary Industries, and the 16 Civil Defence Emergency Management groups.
What happens next
While the mobile alert is a powerful tool, it is only one component of the national emergency communication strategy. Price urged the public not to rely solely on digital notifications during a crisis. In a real-world emergency, officials expect residents to listen to the radio and trust their own “danger sense” to take immediate action if they feel unsafe. The test serves as a reminder that electronic alerts are a supplement to, rather than a replacement for, personal situational awareness.
