Coastal hazards

Understanding coastal hazard risk with the impacts of climate change and sea-level rise is the first step in talking about how we adapt to these challenges.

Communities in low-lying inland and coastal areas around New Zealand and the world are facing challenges with the impacts of climate change and sea-level rise.

Here in Christchurch and Banks Peninsula, the future is expected to bring warmer weather across all four seasons, more days of extreme wind, and more intense rainfalls.

Ongoing sea-level rise is expected to increase flood risks to low-lying communities, particularly round the lower Ōtākaro Avon River, and coastal erosion is forecast to increase in some areas. 

The first step in adapting to these challenges is understanding the risks.
