A new report has revealed the Auckland region’s vulnerabilities and exposure to sea level rises, and insurers have warned of potential premium increases to better reflect the risks.
The report, produced by Auckland Council, found that approximately 1.5-4.5% of Auckland’s land sits in low lying areas that could be exposed to sea level rises ranging from 0.25-3m. With significant population growth in areas exposed to sea level rise, it is estimated that nearly 3% of Auckland’s population is at risk. That equates to about 43,000 people – up from 34,700 people in 2001, NZ Herald reported. The publication detailed that by the end of the century up to 2.5% of the Auckland region might be affected, with a further 3.7% at risk of being swamped by inundation from storm surge, high tides and large waves.
“What we can say is that if we ignore sea-level rise and permit more and more property to be at risk from climate change, then there will inevitably be a day when losses due to sea-level rise, storm surges and flooding become more and more frequent,” Grafton said. “If we continue to do nothing, then insurers will respond by deciding whether they want to accept those risks and, if they do, they will price to reflect the higher risk or increase the levels of excess or the initial amount an insured will have to pay when losses occur.”
“We then need to assess what risks we will retain, what risks we can viably reduce and what risks we want to transfer to others, like insurers. By doing this, we can assess the full impact of climate change,” he added.
