A new report has outlined just how seriously our coastlines are under threat from climate change - and what that means for homes and industries.
The research by the Ministry of the Environment and Stats NZ says that $180 billion in assets is at risk in flood prone areas - that includes 219,000 homes.
Warming seas and ocean acidification caused by increased carbon dioxide levels in the atmosphere are affecting fisheries and aquaculture - industries which contribute over $1b to GDP and support more than 14,000 jobs.
The report says 266 non-native marine species have established populations here - and wetlands, dunes, and native vegetation that help buffer against flooding and erosion, are being degraded or replaced.
The Environment Ministry says the report presents the best evidence available on how the environment is changing and what impact it is having. Kathryn speaks to the Ministry's chief science advisor Alison Collins.
