Twelve percent of New Zealand's national housing value is in a flood hazard area, new research finds. More than 282,000 houses and nearly 159,000 structures like sheds and sleepouts are at risk of flooding, with models estimating they are worth a combined total of $218 billion. The researchers say new construction in flood hazard areas has slowed since 1980, but continues to happen to this day.
