Methodology: Mapping New Zealand’s exposure to coastal flooding and sea-level rise

This report describes the scientific methodology underpinning a New Zealand national scale assessment of coastal flooding as sea level rises. The coastal flooding assessment identifies areas of land exposed to coastal flooding due to extreme sea level plus future relative sea-level rise (RSLR).

This report is intended to supplement the peer-reviewed publication Paulik, R., Wild, A., Stephens, S., Welsh, R., Wadhwa, S.
