Apps, alerts and some fixed sirens will be tested this weekend, as Bay of Plenty Emergency Management carries out their second alerting test of the year.
Director Clinton Naude said the focus for Sunday's test was to make sure the systems and processes in place behind the scenes were all working as they should.
"Importantly, it also provides a valuable opportunity for the public to make sure they're ready should an emergency occur," Naude said.
"If you have a smartphone and haven't already downloaded the Red Cross Hazard App and set it up, I strongly recommend you do. The app is free, and there are instructions about how to set it up so it works for you on the Red Cross website – it's an incredibly useful tool for keeping informed."
The app could be set up to monitor different locations and hazard types, and users only got alerts for the locations they were monitoring.
