On reading the finding above, it's tempting to say maybe climate change adaptation should all be managed at a national level rather than tackled by regional and district councils. However, the most recent Ministry for Environment guidance on coastal hazards and climate change (December 2017) stresses the importance of local government involvement in climate change adaptation.
(From page 37): "For climate change, in particular, consultation or engagement involves the translation of international and national knowledge, projections, trends and scenarios to local levels."
"Ensuring there is balanced and responsible community input into the response options for current and future generations will be an important and ongoing role for local government."
