Earlier estimates of earthquake hazard in New Zealand have been revised by incorporating not only seismological data on known large earthquakes and recent instrumental coverage of small earthquakes but also geological inference from observed ground deformation. The country has been divided into a number of regions, within each of
which the density of earthquake occurrence is assumed to be uniform, while rate parameters very from region to region. The effects of earthquakes occurring throughout each region are then obtained by integration. The results are presented in a similar way as in the earlier study. The estimated hazard is slightly reduced for Auckland, Wellington and Christchurch, and significantly increased for Dunedin.
