Where is the safest place to live in NZ?
..............Move to Hamilton, GNS vulcanologist Graham Leonard suggests.
Nestled inland, Hamilton, population 130,000, is his pick for the most geologically sound city in New Zealand. It's tucked away from the coast - cancelling out any risk of tsunamis - and is a safe distance from known fault lines. If Mt Ruapehu erupts, the volcanic ash is likely to be blown east across the island, and it's far enough away from Auckland's volcanic field to be considered safe.

Even if the Waikato River flooded, it's in a deep enough riverbed that the city is unlikely to be affected, he says.

Sorry Auckland, but precariously nestled on a field of 50 active volcanoes, you could be considered a ticking timebomb. An explosive mix of two types of volcano - maar craters and scoria cones - are peppered beneath the city. The last one to explode was Rangitoto Island, about 600 years ago, so the chances of us seeing an eruption in our lifetime are very, very slim. "But you can't rule it out," Dr Leonard says.
