Over-all risk profiles tended to stay reasonably stable, Hedrich said.
Issues like cyber-security were always high in the rankings.
"But over time we've seen is that environmental risks have risen in people's perception. So extreme weather, natural catastrophes and the risk of climate change adaptation failure are the risks that feature most prominently," he said.
That trend was stood out clearly in the New Zealand results.
"For New Zealand it's a broad range of risks. With climate related risk, extreme weather, topping the chart, closely followed by cyber risk."
The other area which New Zealand respondents ranked high was that of infrastructure shortfall.
This was symptom of strong population growth, Hedrich said.
There was also link between extreme weather, natural disaster concerns and fears about infrastructure - as highlighted by storm-related power outages last year, the report noted.
The risk rankings of New Zealand respondents contrasted markedly with Australians.
Extreme weather and climate change adaptation didn't make the top five in Australia, although energy price shocks topped the list.
Cyber-attack was ranked second.
But then there were concerns about an asset bubble - reflecting the fragile state of the property market in Australia.
The risk of a fiscal crisis rounded out the Australian top five - jointly in fifth place with infrastructure shortfall.
