New Zealand's exposure to seismic hazard has been highlighted dramatically in recent
years through the Canterbury Earthquake sequence (CES) from 2010 to present, and the near-misses
for Wellington during the Cook Strait earthquakes in 2013. These events have generated
unprecedented data and provided a number of lessons that have allowed modellers to develop nextgeneration loss models that are a step change on their predecessors. Improvements include developing
new vulnerability functions based on a wealth of recorded near-source ground motions and damage
and loss data on modern constructions, the ability to explicitly model secondary perils, such as
liquefaction, and utilising state-of-the-art modelling software such as OpenQuake that is being
developed by the Global Earthquake Model. This paper presents a next-generation loss model for New
Zealand and highlight the main drivers of seismic risk in New Zealand from an economic perspective.
