The latest national seismic hazard model has been released today.
It shows New Zealand's risk is 50-percent higher than thought a decade ago - when the last modelling was done.
GNS Science project lead Matt Gerstenberger says it's not surprising - given the latest up to date information.
He says they've taken what they've learned over the past 20 years about earthquakes to give probabilities of shaking over the next century.
