Radio and television stations will broadcast civil defence information and advice before and during a disaster. Ask your support network to alert you to warnings and keep you informed. Contact the emergency management staff at your local council to find out what local warning systems are in place in your community.
Consider installing a system appropriate to your needs such as an alarm with flashing strobe lights to get your attention. Replace the batteries once a year. You may want to consider giving a key to a neighbour so they can alert you to a warning. Keep a writing pad and pencils and a torch in your getaway kit so you can communicate with others.
The following video series contains useful information on the types of hazards that can happen in New Zealand and provides advice on how to be better prepared. The information is presented in both sign language and it is captioned.
