Auckland's unprecedented flooding highlights the importance of climate adaptation finance and the potential for parametric insurance, says David Hall.

Hall, Climate Policy Director at Tohaand until recently Senior Lecturer in Social Sciences and Public Policy at the Auckland University of Technology (AUT), spoke to interest.co.nz for the Of Interest podcast.

Hall says in events like the recent flooding he feels "a sense of grizzly resignation" with what has been predicted "playing out before our eyes."

With the likelihood, as in post-earthquake Christchurch, for a long wait for people who've filed insurance claims due to flood damage to their property, Hall highlights potential for prolonged uncertainty as insurance claims are assessed.

Hall, who recently published a detailed paper on adaptation finance, suggests parametric insurance could complement traditional indemnity insurance. Parametric insurance is a type of insurance contract that insures a policyholder against the occurrence of a specific event by paying a set amount based on the magnitude of the event, as opposed to the magnitude of the losses in a traditional indemnity policy.

"So it could be the severity of the event. [For example], if a flood event reaches a certain level of precipitation, or if an ex-tropical cycle event reaches a certain threshold in terms of wind speed, or drought reaches a certain threshold. Then that trigger is hit and a payout is made. And then people can use that money in a multitude of different ways. They don't necessarily need to use it to pay for replacement or repair of the assets lost or damaged. They might choose to use it in order to relocate, for instance. And so not only does parametric insurance have the advantage of being quick, it also has the advantage of being flexible," says Hall.

"I don't think this is necessarily a replacement for indemnity insurance. But it could be a complement which could give people greater flexibility and certain comfort after events like this." 

He notes parametric insurance is used in Fiji.

"When Fiji gets hit by cyclones or similar events a trigger is struck and a small payout is made to small-hold farmers and so on who are dealing with the consequences of those events. It gives you quick settlement and a bit of liquidity," Hall says.

He goes on to say that parametric insurance products might work better for a public insurance scheme, rather than private insurers, such as EQC as it morphs into the Natural Hazards Commission.

In the podcast Hall also talks about the difficulty of measuring whether adaptation finance is money well spent, insurance retreat, the urgency for climate adaptation and the politics of it plus much more.

Hall was also a contributing author for the Australasia chapter in the Intergovernmental Panel on Climate Change (IPCC) report Climate Change 2022: Impacts, Adaptation and Vulnerability. Additionally And Hall was co-Chair of the Mayor's Independent Advisory Group for Auckland's Climate Plan issued in December 2020.
