New Zealand is vulnerable to flooding due to its varied terrain, significant rainfall, and numerous rivers. Floods can occur suddenly, caused by heavy rain, storms, or rapid snowmelt. They can lead to widespread damage, including property loss, infrastructure destruction, and, in severe cases, loss of life. Understanding the risk factors, being prepared, and knowing how to respond can significantly enhance safety and minimize the impact of floods.

Key Advice for Flooding

Stay Informed

• Monitor flood warnings and updates from reliable sources like MetService and local authorities.
• Download emergency alert apps to receive real-time updates on flood conditions.

Prepare Your Home

• Elevate electrical appliances and utilities above potential flood levels.
• Install check valves in plumbing to prevent floodwater from backing up into your home.
• Keep sandbags or other flood barriers on hand to protect your property.

Emergency Supplies

• Have an emergency kit ready with essentials such as water, non-perishable food, medications, flashlights, batteries, and a first aid kit.

Evacuation Plan

• Know your community’s evacuation routes and have a plan for where to go if you need to leave.
• Keep your car’s gas tank full and have an emergency bag packed with necessities.
• Plan for the evacuation of pets and livestock.

During the Flood

• Move to higher ground immediately if you are in a low-lying area and flooding is imminent.
• Avoid walking or driving through floodwaters, as they can be deeper and faster-moving than they appear.
• If you are trapped in a building, move to the highest floor but avoid attics without exits.

After the Flood

• Listen to authorities for information and return home only when it is declared safe.
• Avoid floodwaters, as they may be contaminated with sewage, chemicals, or other hazards.
• Inspect your home for structural damage, mold, and other hazards before entering.

Communication

• Keep family and friends informed of your status and location.
• Use text messages or social media to communicate, as phone lines may be overloaded.
