Insurance price hikes: Why premiums keep rising so fast

Canterbury and Wellington are being hit harder than Auckland by continued insurance price hikes that the industry says is partly outside its control.

Latest figures from Stats NZ show insurance premiums have increased 6% in the past year, compared to an overall inflation rate of 2.7%.

House insurance prices are up 9.1%, while contents insurance prices up 10.3%.

Insurance comparison website Quashed has seen average house insurance quotes rise 12% and average contents insurance quotes rise 3%.

The Insurance Council said insurance prices aren鈥檛 rising as fast as they were after the Auckland Anniversary Weekend floods and Cyclone Gabrielle and insurers are doing what they can to keep costs down.

鈥淭he impact of repair costs continues to run ahead of general inflation and taxes and levies, which are out of the control of insurers and account for around 40% of a premium,鈥 a spokesperson said.

鈥淚nsurers are also moving toward greater risk-based pricing as more is known about natural hazards such as earthquake and flooding risks, which is also affecting premium levels.鈥

While Wellington has seen stark rises in insurance premiums in recent years, Canterbury is now seeing steeper hikes too.

Quashed鈥檚 data shows average house insurance quotes rising 18% in Canterbury, 13% in Wellington and 7% in Auckland.

鈥淲e鈥檝e seen increases in Canterbury which outpace Auckland and even Wellington,鈥 chief executive Justin Lim said.

Consumer NZ is calling for the Financial Markets Authority to investigate whether risk-based pricing is being applied fairly to all households.

It鈥檚 also calling for the Commerce Commission to carry out a market study into competition in the sector similar to previous studies into personal banking, residential building supplies, supermarkets and fuel.

鈥淥ur research shows people are dropping cover or being priced out entirely, and this will only get worse without serious intervention,鈥 investigative team leader Rebecca Styles said.

Tower Insurance is the latest insurer to make an announcement about risk-based pricing, confirming changes that will see most customers pay less for insurance each year.

The Insurance Council said some properties will cost more to protect than others, with premiums being based on a range of risk factors.

鈥淧roperties on flood plains or near major rivers are more prone to flooding during heavy rainfalls, while those in regions with higher seismic activity are more susceptible to earthquake damage,鈥 it said.
