The Council has commissioned several reports over a period of years to gain a comprehensive understanding of sea level rise and its potential effects.
The 2017 Coastal Hazard Assessment for Christchurch and Banks Peninsula will be the most up-to-date information on coastal hazards across these areas. It is currently being finalised and due for release in September 2017.
The 2017 Report is the result of a thorough and independent peer review of the 2015 Coastal Hazards Report.
A peer review panel made recommendations for changes to the 2015 report and further investigations. These recommendations have been addressed in the 2017 report. The report has been independently peer reviewed to ensure it met the panel’s recommendations.
It will be available once it has been received by the Council.
