"There will be losses and damages. Opportunities will also arise for new and innovative ways to adapt. We need to act now to address the ongoing changes to our climate."
Coastal Hazards joint committee chair Peter Beaven said the report at last demonstrated a commitment on the part of central Government to take a lead role on this critical issue.
"As the report states, many local authorities such as Hawke's Bay have already taken a proactive stance and begun work, such as the Coastal Hazards study commissioned by three of our local bodies here in response to sea-level rise.
"However, the report is far more wide-reaching than just coastal hazards in considering the impact of global warming," Beaven said.
"There will be impacts on biosecurity, infrastructure, insurance availability, frequency and severity of floods to name just a few."
He said every local authority should have the effects of global warming front and centre of its thinking, not only in terms of adjusting to climate change with structures such as higher stop banks and mitigation measures, but also minimising global warming through activities such as afforestation, electrical vehicle uptake and use of alternative energy.
"It's obvious we can't do this by ourselves. It needs the active support and co-operation of both central Government and the wider community," Beaven said.
Local Government New Zealand also welcomed the report, which president Dave Cull said picked up on what local government had been calling for, particularly a national adaptation plan, engagement with communities on the effects of climate change and discussions around adaptation funding.
"We now need to take these recommendations further and with the Government work through the options and how to implement them in order to make real progress that will build the resilience of our communities."
There were still sensitive questions that central and local Government must collectively discuss with businesses and communities, Cull added.
"We need to have conversations about sensitive issues that we must address if our communities are to be resilient, such as how to manage the relocation of communities shown to be at risk in a national risk assessment, and whether existing insurance models are sufficient."
"We are looking forward to working with the Government on addressing the adaptation challenge.
"Real and urgent action now is critical – we can't rest on our laurels any longer."
