How Climate Change Will Impact Your Wallet: Understanding the Substantial Financial Costs Ahead

New Zealand faces serious challenges from climate change, according to the Independent Reference Group (IRG), formed by the Ministry for the Environment. They warn that without changes, the country could see rising costs related to natural disasters, declining insurance options, and significant financial strain on individuals and governments.

The IRG emphasizes the urgency of addressing these issues to prepare for climate impacts. Their recent report outlines how different sectors—like local governments, banks, and insurers—experience these challenges. The group asserts, “We need to act now; our current state isn’t enough.”

Cyclone Gabrielle stood out as New Zealand’s costliest non-earthquake disaster, estimated to impose losses between NZ$2 billion and NZ$4 billion, surpassing even the losses from the 2016 Kaikōura earthquake. Recent severe weather events in 2023 are projected to cost even more, between $9 billion to $14.5 billion. These figures are red flags about the increasing frequency and costs of such events, especially for insurers.

The IRG highlights several current issues:

• Access to Information: There’s inconsistency in climate hazard information, making it hard and costly for property owners to understand risks.
• Property Prices: House prices do not reflect the true risks in areas prone to floods or erosion.
• Local Government Limitations: Local councils often lack the powers needed to effectively manage these risks.
• Funding Challenges: Investments in flood protection are mainly local but funding options are limited.

The IRG warns that past government buyouts can encourage a false sense of security, making residents expect help for risks they haven’t managed themselves. “Expecting buyouts can create moral hazards,” they explain. Instead, they advocate for personal accountability in understanding local risks.

As the climate crisis deepens, the cost of insurance rises too. Insurers are reportedly shocked by recent event damages, prompting them to increase premiums and shift more financial risks to local companies. A study indicates that average annual losses from floods could surge by 19% to 26% by 2050, threatening the availability of affordable insurance, especially in high-risk areas.

The IRG stresses the need for proactive planning rather than waiting until disasters strike. “The wide-ranging impacts of climate issues go beyond immediate costs,” they state, highlighting effects on lower-income communities and Māori, who may bear the brunt of climate risks.

The report calls for urgent action in three key areas:

• Risk Awareness: New Zealanders need clear information about potential hazards. Access to risk data allows people to make informed choices.
• Funding Responsibilities: A “beneficiary pays” approach should be adopted, ensuring that those who gain from risk mitigation contribute fairly.
• Adaptive Actions: Individuals should take charge of their circumstances, recognizing risks in high-threat areas. Those risks should influence property values and insurance costs.

The IRG suggests a 20-year transition period, giving people time to adjust and providing support where needed. They recognize the importance of empowering Māori communities to make local adaptation decisions for their land.

In conclusion, the IRG’s findings highlight an urgent need for change to help New Zealand adapt to looming climate challenges. For a detailed look at their recommendations, visit the Ministry for the Environment’s report here.
