Massey University's Michael Naylor says the Treasury needs to be bolder and to rethink the purpose of EQC, including the possibility of focusing on offering reinsurance cover to private insurers

By Michael Naylor*

The proposals in Treasury’s newly-released review of the Earthquake Commission (EQC) are weak, and do not solve many of the current problems oppressing Christchurch residents.

Suggested changes include dropping contents cover and increasing the EQC sum covered to $200,000. While these reforms are sensible, they are unimaginative and go nowhere near far enough.

Given the multiple problems of the dual insurer model exposed during the Christchurch rebuild, the Treasury needs to be bolder and to rethink the purpose of EQC, including the possibility of focusing on offering reinsurance cover to private insurers.

For insurance companies, the difference between natural disaster insurance and other types of insurance is that natural disasters have a capacity to impact on a high number of insured clients at the same time, causing company bankruptcy. This is normally offset by insurance companies purchasing ‘excess-of-loss reinsurance’, which involves a large worldwide reinsurer agreeing to pay all losses from an event which are above an agreed sum.

In theory there is no reason why the EQC can’t be replaced by a law requiring all private insurers to hold this type of cover. In practice there are difficulties. One difficulty is that this reinsurance cover can be expensive to obtain at a reasonable price, which pushes up client premiums. This is why AMI purchased ‘fixed-sum-reinsurance’ instead, and went bankrupt after losses exceeded their capital plus the fixed amount of reinsurance. This difficulty becomes worse for smaller insurers as they have lower client diversity and a higher potential percentage of loss. The area is also quite technical and smaller insurers may lack the skill needed.

Treasury argues that the EQC can provide a small amount of ‘first insurer’ disaster cover cheaper than the private sector can. However the sum they are recommending the EQC cover is only the first $200,000. Given the average New Zealand house rebuild costs vastly exceed that, this still exposes private insurers to losses above that sum; losses which are uncertain and unlimited.

That’s why Treasury also requires that insurers hold enough capital or reinsurance to survive a 1-in-1000-year event. This is very costly, which pushes up premiums and is only secure if actuaries’ estimate of the size of the most extreme event holds true. These proposed EQC arrangements do not remove the bankruptcy risk from New Zealand insurers, or from the New Zealand taxpayer. They are also very inefficient and costly.

The other issue identified in the report were the problems created by the EQC being first point of contact for all claims. This proved a disaster during the Christchurch earthquakes because the EQC simply didn’t have the systems or staff to cope for at least 18 months. The EQC pre-quake was set up to handle a small number of routine claims but the Christchurch quake forced them to expand from about 70 staff to over 1800, with a large number needing specific technical skills.  

Because all claims had to be screened by the EQC, private insurers could not proceed until the scarce EQC staff had screened customers. This meant they could not use their greater capacity until much later in the process.

The Treasury report sensibly recommends that private insurers act as the first point of contact. Handling a major disaster is easier for private insurers to deal with as they are, in general, large worldwide companies employing thousands of staff with the necessary skills. They can fly in staff or use their armies of foreign staff, rather than poaching them from existing insurers or using expensive contractors, as EQC did.

Under the Treasury recommendations, however, the EQC would still have to deal with thousands of claims and private insurers will have to handle claims which they will not ultimately pay for – and this will push up premiums.

There is really no justification for the EQC to be involved in quakes that are smaller than disasters, and when large disasters happen the EQC will never be ready, given their small staff size during non-crisis periods. The Treasury proposals still leave us stuck in the quagmire of the two insurer problem.

The Treasury needs to take a step back and think a bit deeper. The ultimate objective of providing widespread and low-cost disaster insurance could be better achieved at a cheaper price if the EQC removed itself from customer contact. A superior option could be for the government to require all private insurers to provide disaster cover as part of house insurance at a fixed price nationally, and then to require those private insurers to arrange adequate excess-of-loss reinsurance. The EQC would then focus on helping arrange that reinsurance for those insurers unable to arrange it themselves at an attractive cost. The government’s size and sovereign rating would enable it to buy this cheaper than most private insurers. This would also enable the removal of the 1-in-1000-year capital requirements, further reducing premiums.

Private insurers would be able to deal with the routine quake claims at little extra cost to their administration systems. Bare land could be covered via new products created by private insurers but backed by the EQC.

An alternative to reinsurance would be the issue of ‘cat bonds’. These are bonds that do not pay out to investors if a selected event occurs, which could be defined as an earthquake above a certain cost. These bonds could be issued far cheaper and easier by the EQC than private insurers but they are are currently, and bizarrely, banned from use.

The EQC would then be a small group of specialists who could focus on financial arrangements, on funding earthquake and building science and on researching and preparing post-disaster management. The EQC could take on a role equivalent to Cera, as well as overseeing and regulating the work of private insurers during a rebuild.
