Many Kiwis' Sunday afternoons would have likely been interrupted by the alarming sound of an emergency mobile alert.
Thankfully the alert was just a test but for those who didn't hear anything – there's an explanation.
National Emergency Management Agency (NEMA) director John Price said overall the test was a success with it transmitted to all parts of New Zealand with cell phone reception.
"Our 2023 annual preparedness survey showed 90 percent of people received an alert or had been with someone who had. Given this year's successful transmission, we can safely estimate over 5 million phones will have received the alert," Price said.
He said NEMA has carried out six nationwide tests of the system since it was launched, and it has "shown itself to be an extremely reliable channel for pushing emergency messages to people in New Zealand when there is a severe threat to life, health or property".
"It's important to remember that Emergency Mobile Alerts are not meant to replace other ways of staying informed, such as radio, TV, social media and online channels, or the need to take action after natural warnings. If you feel in danger, don't wait for an official warning. Take immediate action. Remember - your safety is your responsibility.
"Starting today, we'll be undertaking this year's independent Annual Preparedness Survey. This survey will help us to better understand how people stay informed during an emergency, and how many people received the test alert."
Price said they're keen to hear feedback from people about whether they received their alert through their website.
For those who didn't receive an alert, there are several reasons for it."We encourage you to rely on several different ways to stay informed. For help with troubleshooting visit the Emergency Mobile Alert troubleshooting page on NEMA's Get Ready website."One of the reasons could be the variability in how phones pick up the alerts.
Price said while the system itself is reliable, people will have a range of experiences due to the variability of how different devices receive the alerts.
"For example, we have received comments around the alert sound not overriding silent mode on some phones, and people not being able to find the alert message after dismissing the sound."Unfortunately, these are quirks of the operating system on your phone, to do with the phones manufacturer and not something we can control.
"Good news is, if you have dismissed the alert, it may still be viewable on your phone."
For Android phones:
Although each Android phone is different, emergency alerts are generally found in your 'Messages' app.
For example:
Go to Messages app
Find the menu (...) and select 'settings'.
Select 'Emergency alert history'.
For Apple phones:
The alert will be in your notifications. Access your notifications by swiping down from the top of your screen. If you delete your notifications, you will also delete the alert.
