Ruapehu civil defence debrief highlights growing climate change challenges

Ruapehu civil defence is readying itself for more extreme weather events it says are becoming more frequent as a result of climate change.

The organisation has concluded a "warts and all" look at its response to a cyclone in March and also April's torando that ripped through National Park.

Ruapehu Emergency Management Officer Nick Watson said that while the overall response to both events went well there was always something that could be learnt.

"The debrief process is a 'warts and all' look and what we did well and what could be improved upon with the objective of organisational learning and helping to ensure we respond even more efficiently and effectively next time," Watson said.

"While both events could be considered small in civil defence terms they caused major damage and disruption to the communities they impacted upon and for a small council like Ruapehu place a significant demand on our staff and other resources."

"Both events highlight the impact of climate change as we experience a lot more frequent, geographically smaller, but significantly more intense weather events that are very hard to predict and cause a lot of damage in the area they hit."

The cyclone over March 7-8 caused multiple large slips and destroyed farm fencing, tracks, culverts and district roads requiring council to assist with the flying in of water tanks, culverts, food and other supplies to affected areas where necessary.

Major slips also trapped over 100 tourists at the Blue Duck lodge at Whakahoro on the Retaruke River who needed to be evacuated by helicopter.

The National Park tornado on April 10 tracked along a narrow path where it caused significant property damage making a number of families homeless and requiring part of the village to be cordoned off.

Between them the council response and infrastructure recovery cost is estimated to be in excess of $1 million.
