"Tsunamis are rare events, but that very fact makes understanding the risk and knowing what to do and where to evacuate before a wave strikes, vital,'' he said.
"Testing our alert systems allows us to practice our activation procedures, ensure the systems are functioning correctly and helps to increase public awareness around responding to emergency events."
"For those that have registered for text alerts this means that this Saturday you will receive a text not long after 12pm as part of the test. For those who haven't registered for text alerts or email updates, there is still plenty of time, you simply need to visit our website or call our toll free number".
Saturday's test at 12pm will include:
•Text alerts
•Email updates
•Social media updates on facebook.com/bopcivildefence and twitter.com/bopcivildefence
•Fixed sirens will also be tested in the eastern Bay of Plenty
