The EQC staff and management have copped a lot of criticism along numerous fronts, including nest-feathering accusations and, rightly, when such vast sums of money are flowing through the system it should be transparently disclosed.
But there are other hidden costs. A couple of EQC frontline assessors told me they're getting frustrated by the amount of shoddy work being turned in by some contractors, skimming on quality but claiming full whack from the taxpayer.
"It's fraud," one particularly dogged assessor told me, "and it makes me really angry both as a professional and a taxpayer."
He showed me pictures of a foundation repair job where the mortar could be scraped out like it was pure sand.
"How big's the problem?" I asked him.
"It's huge," he said.
Of course, it's just about impossible to gauge the truth of this anecdotal evidence isn't enough.
But the EQC has been spending its funds faster than anticipated. According to the 2012 report, the EQC fund is down to its last $3 billion or so (while it's also due another $4.1 billion in reinsurance money).
By May this year it had sold down all its equity holdings, including $1.4 billion of global shares, with the remainder held in NZ government stock and bank securities.
The rapid sell-down of the EQC equities investments has also had another, possibly expensive, effect.
"A significant portion of the investment portfolio was sold down before EQC's 10-year target could be achieved," the 2012 report says. "For the five years to 30 June 2012, the actual total portfolio return was 5.1 per cent versus the target of 9.9 per cent."
For the time-being the investment strategy of the EQC fund will obviously be moot but, as with the city of Christchurch itself, its rebuild is underway.
"... EQC's premium increased from 5 cents to 15 cents per $100 sum insured from 1 February," the report says. "This will increase the Commission's annual levy revenue from about $86 million to about $260 million."
