What are natural disasters and how can you minimise your risks if they occur?
Natural hazards and natural disasters
A natural disaster is an event caused by forces beyond human control that causes great damage to property and, in the worst cases, people. Natural disasters can include
- severe weather events, including storms, wind and rain
- volcanic and hydrothermal activity.
Each of these is called a natural hazard until it happens, after which we call it a natural disaster.
Risks to New Zealand
New Zealand is a small island nation on the Pacific Rim. Our location makes us vulnerable to natural hazards.
New Zealand sits on the Ring of Fire subduction zone, where the Earth's Pacific- and Australian tectonic plates meet, causing increased seismic (earthquake), volcanic and hydrothermal activity. Our large coastline and the lack of other islands between us and the Pacific Ocean increases our tsunami risk. And the fact we're positioned in the "roaring forties" - an area of the planet exposed to strong, westerly winds - subjects us to frequent extreme weather, including winds, rain and storms.
Our vulnerability to natural hazards is clear in our history, and the Canterbury and Kaikōura earthquakes are proof of the importance of building our resilience against natural disasters.
Resilience is about our ability to recover from loss or damage, particularly when that loss or damage is widespread.
ICNZ and insurers actively engage with central and local government and other stakeholders to raise awareness of natural hazards and promote New Zealand's resilience.
In 2013, ICNZ has developed a 15-point plan called Protecting New Zealand from Natural Hazards to help reduce the social and economic impact of natural hazards in New Zealand. It urges decision-makers to implement a range of legislative and strategic recommendations because of New Zealand's ongoing status as one of the most vulnerable countries to the impact of natural disasters on an economy of our size.
Following the steps in this plan will help keep insurance available and affordable for all.
Insurance's role in natural disasters
Without the help of the insurance industry, the community would have faced more than $24 billion in additional costs to recover from the Canterbury and Kaikōura earthquakes.
ICNZ and the insurance industry aim to make New Zealand more resilient to natural hazards and natural disasters by educating the public about the risks they pose and by providing insurance to help manage those risks.
Reinsurance is critical
Reinsurance is like the insurance our insurers have. It helps them pay for large-scale disasters.
The Canterbury earthquakes were by far the most damaging and expensive natural disaster New Zealand has ever faced. They were so huge, and cost so much, that insurance policies in New Zealand changed to allow cover levels (and reinsurance) to be more accurately calculated. As a result, the cost of cover rose.
Local insurers are working hard for New Zealanders to maintain the supply of affordable reinsurance from global providers, at a time when there has been a rise in dramatic and costly natural disasters around the world. Canterbury will benefit from more than $22 billion in reinsurance money through private insurers alone — more than 15% of New Zealand's GDP. Without strong investment in insurance, bearing this cost through other means would have been a massive burden on our small nation.
How the insurance industry responds in emergencies
All ICNZ members have emergency response procedures in place. These procedures allow them to deal with the large numbers of claims that are expected after emergency events.
Their emergency response procedures include
- special call centres
- teams of specially trained loss adjusters
- technical advice from ICNZ.
In a disaster, ICNZ's role is to
- gather information on the nature and severity of the emergency event and pass it on to your insurer
- provide information to you through the media and our social media channels
- facilitate coordination between your insurance company, your local council and EQC.
