GV27:
Their first term was from 2008 to 2011; during which there were two stonkingly massive earthquakes.
Only one stonkingly massive one. In terms of damage (rather than "magnitude") the other (first one) was what NZ should expect as likely to happen every few years. That's what insurance and EQC is for.
And as for that big one, despite the government having to top up a few billion dollars (EQC reserves and reinsurance payouts were not "government money"), the >$30 billion of so that was paid out by insurers (and to them by reinsurers), when used in the rebuild was a significant boost to the economy, and the government coffers benefited from both the GST on the rebuild expenditure, and the increased PAYE and business tax due to the significant boost in local economic activity. They clawed back.
How the government and EQ minister handled that is another matter, but using the Chch quake as an excuse for anything to do with National's general performance isn't new. The MP for Ilam spent years bleating about how much "the government" was spending, when the vast majority of what was being spent wasn't theirs. Of what they did spend though, a hell of lot was wasted (by EQC/EQR) many people were telling them this at the time - and it's turned out they were correct. It was a shambles.
