As fire operations on Christchurch’s Port Hills continue into day six, Fire and Emergency (Fenz) say the blaze is contained but is not out.

Fire and Emergency incident controller Steve Kennedy said crews currently are focusing on around 40 hotspots that are considered at risk.

“Conditions have changed around Port Hills since there is some cool weather today, [Fenz] managed to fly helicopters around and the drones have identified new 17 hotspots overnight,” he said.

“Fortunately with it being a bit cooler, it’s probably a bit easier on our crews up there, so it’s not so hot.”

“We are aware of the fatigue factor with our crews and making sure that they’re getting plenty of rest and hydration up there as well,” Kennedy said.

Kennedy confirmed there are still around 120 people working on the incident ground.

“The vast majority of them are firefighters on the ground, which would be 100 plus, we’ve still got four aircraft available for us down here as well.”

The fire operations around the Port Hills are expected to run until at least Thursday.

“We are hoping as time goes on and once we get past the weather conditions today, we may be able to start reducing crews,” he said.

It comes as today is flagged as a high fire danger day across Canterbury because of the windy and hot conditions.

MetService meteorologist Gerrard Bellam last night said Canterbury High Country would be under a wind warning until 3pm this afternoon.

“The severe northwest gale in these areas could gust up to 130km/h in exposed places, but it will be a short and sharp spell of wind.”

The east of the South Island can expect high 20C-plus temperatures, but temperatures are likely to then drop significantly in the afternoon, Bellam said.

Kennedy said that means any new fires will move very quickly and be hard to bring under control.

“We have the resources to respond to multiple incidents, but we’re asking everyone to do their part to prevent any more fires starting,” he earlier said.

Christchurch City Council controller Brent Smith said: ”We’re still under a state of emergency and we will do so until we get to the point where it doesn’t require the multi-agency effort.”

“We want to thank the public for the patience and the respect they’ve given the firefighters here, it’s made it a lot easier to get their job done and it is having a look at the fire ground,” Smith said.

Meanwhile, 50 firefighters are working to get on top of a scrub fire in North Canterbury.

Five helicopters responded to the fire but three with monsoon buckets were grounded due to the wind, while the other two with specialised equipment are continuing to operate.

“The fire is currently uncontrolled and has largely burned out, but remains a risk due to high winds,” a Fenz spokesperson earlier said.

There have been no reported livestock losses, or any structures lost or damaged.
