As of 2019, roughly 72,000 people in New Zealand are exposed to coastal flooding – about 50,000 homes worth at least $12.5 bn. Around 43,000 Auckland residents are directly threatened by rising sea levels, and at least 10,000 houses across New Zealand’s four major coastal cities are at risk of becoming uninsurable within the next 30 years.
Local Government New Zealand (LGNZ) estimates the amount of local infrastructure exposed to sea level rise to be in the realm of $14 bn, but adds that that is a conservative estimate.
