You may have heard the term 'risk-based pricing'. This relates to the way insurance is calculated and is based on how 'risky' a place is to live. New Zealand has many natural hazards, or risks, including floods, earthquakes, and landslips, and some places are riskier than others. As these types of events are harder to predict, we use statistical modelling carried out by actuaries and scientists to help estimate the probability and impact of these events.
As New Zealand continues to experience earthquakes and more frequent and severe weather events, the number of claims continue to increase, which also increases the cost of reinsurance.
Previously, the difference in risk across the country wasn't always fully reflected in premiums. That's because it was often balanced using cross-subsidisation, so premium differences were off-set by other customers.
To make sure we can continue to provide cover for our customers long term, we have had to consider the way we calculate premiums to better include natural risks.
Will this change the cost of my home insurance?
All areas in New Zealand carry a different cost of reinsurance which we will now take into consideration when pricing home insurance policies. This means that customers in areas with a higher risk of natural hazards, such as earthquakes, floods, and landslips may see an increase in their premium.
