I knew NZ was prone to earthquakes but didn't really understand how dangerous it can be. It seems too nice.

Christchurch, the city that bore the brunt of the 2016 quake, wasn't even considered to be the place most at risk - the fault line that opened up there was a completely new one.

The risky place was supposed to be Wellington, which is right on the top of a known fault line.

Meanwhile Auckland, on the north island, which is not considered prone to big earthquakes, is built on the top of an active volcano, which will erupt at some stage in the future.
