Auckland Council data given to the Herald showed the region has 52,000 properties sitting in a flood plain - of these 8000 faced the risk of buildings flooding above the ground level in the case of an extreme weather event. Including properties located outside the flood plains the data indicated 3.2 per cent of the region's properties; 16,000 homes, commercial or industrial buildings were exposed to a flood risk - but around half were due to rainwater flows on the ground. "The extreme rainfall intensities were localised so we would expect only a portion of the properties at risk of flooding in the region to flood." Relab provides a simplified summary of a property's flood risk.
