Re: At least most of the country moved away from Australia
You're talking about a country with more land area than the UK, and one-fifteenth of the population. And three-quarters of that one-fifteenth are in the North Island, the closest point of which is at least 100km from the epicentre.
And it's summer, although it has been raining quite a bit.
So the low casualties, while gratifying, aren't that surprising. And calling the country "comprehensively fucked" would be like calling the UK "comprehensively fucked" if Brighton Pier collapsed. (I mean, it is fairly fucked, but the earthquake is a relatively small part of that.)
