Integrating tsunami inundation modelling into risk-based land-use planning: an update of guidance

This guidance report is an update on the 2011 GNS Science guidance aimed at land-use planners and decision makers on how tsunami inundation modelling can be incorporated into land-use planning to reduce the risk posed by this hazard (Saunders et al. 2011). This updated guidance retains the format and content of the original document where appropriate. The basics of tsunami are again provided, along with identification of the key pieces of legislation governing natural hazard risk in New Zealand and how they can contribute to managing tsunami risk. The opportunity was taken to update the guidance to reflect recent changes to legislation in New Zealand and emphasise the latest approaches to the risk assessment process.
