New Zealand's $64 Billion Spend On Natural Hazards Heavily Skewed To Recovery Over Resilience
Press Release – IAG New Zealand
Amanda Whiting says: It is clear we need to do more to reduce natural hazard risk, especially when we know that there is a strong case for doing so. International research shows that a dollar invested in risk reduction can reduce spending on response and …
Research commissioned by IAG New Zealand shows that the Government has spent at least $19 billion on responding to natural hazards since 2010, and a further $14 billion through its public insurance schemes.
When the $31 billion spent by private insurers is included, the total cost of natural hazards since 2010 is $64 billion. Adjusted for inflation this equates to an average of $5.5 billion per year, of which the Government's share is about half.
IAG New Zealand CEO Amanda Whiting says: 'This research highlights again the significant financial cost that natural hazards have on New Zealanders, and the urgent need to reduce their impacts.
'These costs represent a drag on our economy and work against the growth and financial strength required to support the needs and aspirations of New Zealanders.'
The research also shows that 97% of the Government's expenditure was on responding to and recovering from natural disasters, with the response to the Canterbury earthquakes, Kaikoura earthquake and the North Island weather events of 2023 dominating spending. Only 3% was spent on risk reduction and resilience.
The total amount spent, will in fact, be much higher. This is because this research does not include significant spending by local government, such as the $8.2 billion that the Christchurch City Council is projected to ultimately spend on recovery in response to the Canterbury and Kaikoura earthquakes. It also does not include the wider social and economic costs which Deloitte suggests could account for at least 50% more cost [1].
Amanda Whiting adds: 'It is clear we need to do more to reduce natural hazard risk, especially when we know that there is a strong case for doing so. International research shows that a dollar invested in risk reduction can reduce spending on response and recovery by four dollars [2].
'Reducing natural hazard risk is as much about improving the decisions we make as the money we spend to improve the safety and resilience of our homes, businesses and infrastructure.
'It is also clear from this research that New Zealand has an incomplete understanding of the costs of its natural hazards. Fixing this will enable better decisions to be made on when, where and how to reduce risk. This is becoming even more important as natural hazard events increase in frequency and severity.
'We need to prioritise improving how the actual costs of natural hazard events are recorded by central and local government, so that we know how much we are spending, on what and where. Alongside this, we must quickly move to understand the underlying trends, regularly model the expected financial impact of natural hazards, set relative benchmarks and closely monitor changes in risk over time.
'IAG continues to invest significantly in data and its application to improve decision making and is working with government and other partners to put this capability to use in improving how natural hazard risk is managed. This is a priority for us and must be a priority for New Zealand.'

Letters: The ABC of boys' education needs a reintroduction; should we add Joe Schmidt to the NZ Rugby board?
(b) They have a clear focus and structure and know the limits and consequences. (c) There's a real challenge to action of some sort. At the time, we summed up these findings under three headings: Affirmation, Boundaries and Challenge. In short, an ABC of boys' learning. After staff feedback, each of these three vital elements was broken down into practical suggestions for teacher action that would maximise boys' enthusiasm for, and confidence in, classroom (and school-wide) learning. These ideas seem similar to what is being arrived at again in 2025, but it was useful to have them reduced to a clear, simple package that teachers could use on a daily basis. Maybe the ABC needs a reintroduction. Alister Williams, Waikanae. Ferry fiasco Nicola Willis demands accountability from everyone except herself. The cancellation of the Irex ferries project was done with little thought as to how it would affect the country as a whole. First, the Government waits nearly a year after the cancellation to appoint a Railways Minister who occasionally makes an announcement that there will be another announcement in the future. Meanwhile, our ferries, which are the lifeline between islands, either break down or get consigned to the scrap heap. Under Irex, we would have had the new ferries next year, but it is suggested it would be a risk to your life if you held your breath for the now-promised date of 2029. The cost of cancelling the Irex ferries is still a secret and we don't know the cost of the promised new ones. Unfortunately, we got a Toyota instead of a Ferrari when the PM appointed the Minister of Finance. Reg Dempster, Albany. Strategic infrastructure It's easy for people to be critical of the current Government over its decisions on the contract for new ferries. But the real issue goes beyond that instance. Major strategic infrastructure projects have been politicised for more than half a century. Our politicians play their ongoing games of one-upmanship and there are no winners, only losers - the people of New Zealand. The ferries and rail connections between the North and South Islands have been an integral part of the national transport system for how long, 70 years? Maybe more. No surprises, then, that it's a piece of strategic infrastructure that deserves better than the petty childish games our politicians play. It doesn't matter which party they are from, they are all the same. So, people of New Zealand, try not to cherry-pick your political targets when it comes to infrastructure projects. Instead, demand a better deal from all our politicians with respect to major/strategic projects. It's not difficult to identify them, is it? Phil Chitty, Albany. Tagging on and off I fail to understand why AT would charge senior citizens for forgetting to tag off. AT's website says that, if you fail to tag off, you will be charged the full cost of the journey to the end of the route. If you travel after 9am on a SuperGold Card, there is no cost for any part of the journey. So how can charging for a non-concession fare be reasonable? Kathy Simpson, Freeman's Bay. Troubled times for NZ Rugby Gregor Paul's 'Rugby Revolution' (June 8) is an excellent review of the troubled times at NZ Rugby with All Blacks coach Scott Robertson's appointment, the captaincy, selection and game plan questions. Not the hoped-for transition, and we are expecting better this year. A new CEO will help. The great loss to NZ Rugby was that Robertson could not find room for the very talented Joe Schmidt in his coaching team when asked to by NZR. It has not gone unnoticed how successful Schmidt has been with the Wallabies, a tenure ending when he hands over to Les Kiss at the end of the year. Perhaps NZ Rugby could offer Schmidt a seat on the NZR board on his return to New Zealand. It would be a shame to lose this level of rugby intelligence twice. Gary Carter, Gulf Harbour.

We need to fix the human-shaped hole in our economy
Specifically, I mean the flow of humans across our border. We are a very small country, with a total population the size of Sydney. So, whether it's tourists or immigrants, the fluctuations in the number of people leaving and entering the country have an outsized impact. When the numbers fall dramatically, as they have done, we feel it acutely. There is a human-shaped hole in our economic recovery. We had more good news out of the primary sector last week. A Government report forecast primary sector export earnings will hit $59.9 billion in the June 2025 year – $3b higher than was projected in December. That's a big stimulatory boost on top of already strong earnings. But we had more bad news out of the retail sector. Electronic card transaction data for May showed consumers are still feeling cautious. We should have had more money in our pockets thanks to lower petrol prices and lower interest rates. But core spending (which excludes fuel) was down 0.2% in May, with falls for durables and consumer goods. Hospitality and apparel were basically flat, up just 0.1%. There really aren't any obvious signs of recovery there for the beleaguered Auckland CBD. It's a tale of two economies, and there's a big divide opening up. It would be interesting to compare and contrast the vibe at Fieldays this weekend with that on Queen St. Last week, we also saw the release of new immigration and tourism data. These provided a timely reminder of what the missing pieces of this economic recovery are. Our annual net migration gain dipped to just 21,300. That's still population growth and I suppose we should be thankful for it. However, if we put aside the Covid years when the borders were closed, it is the country's lowest rate of population growth since January 2014. Back then, things were building up again after a post-GFC exodus. Since then, our economy has grown used to running with high levels of net migration gain. From 2015, it ran between 50,000 and 70,000, which everyone thought was pretty wild at the time. But after we opened the borders post-Covid, things really took off. New Zealand's net migration gain soared to a record peak of 138,000 in the year to October 2023. It pushed the economy to the limits of its ability to cope. But it also meant unprecedented demand for housing, cars, furnishings and all sorts of other retail goods. Every new immigrant has to live somewhere. Most drive cars. So the big fall in numbers – a combination of fewer arrivals and record departures – puts a huge dent in demand relative to where the economy has become used to operating. Then there is tourism. New Zealand had about 3.6 million overseas visitors in the year to April. That's a big number relative to our population and illustrates just how important tourism is to the economy. But it should be much bigger. Stats NZ points out that the visitors in April 2025 represent just 86% of the total we got in April 2019. Not only have we not yet returned to pre-Covid levels, but the current trend suggests we aren't about to any time soon. The tourist spending deficit looks even worse for our economy if we assume that, without the big Covid break, we might have achieved some degree of growth in the past five years or so. What can we do to address this human-shaped hole in the economy? Clearly, the Government is well aware of the problem. We saw two new policies unveiled last week to try to shift the dial. On the tourism front, it was back to the future with the $5.5 million reboot of the '100% Pure' marketing campaign around the world. That successful slogan was ditched in 2022 for 'If You Seek', which doesn't seem to have made much impact. That change is unlikely to shift the dial massively. The big issue with tourist numbers right now is the drop-off in Chinese visitors. The consumer end of the Chinese economy has been struggling too, and New Zealand is an expensive place to visit. Prime Minister Christopher Luxon will be hoping he can drum up some renewed hype about New Zealand when he visits China late this month. Based on our relationship with China though, and the surge in tourist interest after the free trade deal in 2008, the real key to a renewed tourist boom likely lies with India and the publicity a free trade deal there might bring. On the immigration front, the Government has introduced a new Parent Boost policy, which will enable the parents of immigrants to stay for up to 10 years. That should add to the appeal of New Zealand for many migrants. But the reality is most immigration is driven by economic factors. Immigrant numbers are unlikely to pick up until our job market does, which means we can't rely on it to drive growth in the short term. It's probably good for our economy to sweat it out with lower than average net migration for a while. House prices are balancing out, and this provides a chance for infrastructure planning and building to catch up. But we need to turn the trend around soon. We especially need to stop the youngest and brightest Kiwi workers from departing in high numbers. The boom and bust cycles we seem to perpetually swing through are no good for long-term stability. The goal of this Government and the next should be to encourage a steady pace of population growth, perhaps in the range of 30,000-40,000 net gain per year.

More claim social development benefits during May
Unemployment is at 5.1 percent through May. Photo: JES2UFOTO Latest numbers show 27,243 more people received a benefit in May, compared to the year before. The Ministry of Social Development's monthly update shows the number of people on a benefit in New Zealand rose by just over seven percent to 403,311 in that time. The unemployment rate is 5.1 percent. Most of the increase is due to people accessing JobSeeker support - there was an 11 percent rise of just over 21,000, to a total 213,831. In May, 9.5 percent more people found work, compared to the same time last year, but eight percent more benefits were cancelled than a year ago - a total of just over 6000 - for other reasons, including sanctions. The Government aims to reduce the number of people on the Jobseeker Support benefit by 50,000 by 2030, introducing a traffic-light system and new non-financial sanctions , and changing the re-application for job seekers to every six months, instead of each year.
