A wildfire on the Chatham Islands 700 miles east of New Zealand has burned about 2,000 hectares (4,900 acres).

Principal Rural Fire Officer Craig Cottrill says two teams of five specialist rural firefighters and four incident management team specialists will fly via charter aircraft at 3pm on Saturday 3 February with fuel, equipment and supplies for a two-week deployment. Two helicopters with monsoon bucket capacity are also set to arrive on the island.

They will join eight Fire and Emergency volunteers, four Department of Conservation staff, and three local contractors working to contain the fire. It has started to burn into conservation land, however the true extent of the fire will be determined once additional crews are on the ground.While the fire is currently burning towards the southern coast, a wind change to the north is in the forecast overnight. Accordingly, 19 households along the Waitangi Wharf – Owhenga Road have been evacuated to a welfare center operated by the Chatham Council Civil Defence as a precaution overnight.

Wildfire threatens Christchurch, New Zealand

(UPDATED at 9:05 a.m. MST February 16, 2017)

The wildfire at Christchurch, New Zealand was slowed by light rain Thursday night and more precipitation is in the forecast for Friday.

Officials are reporting that 11 Christchurch homes and two outbuildings have been destroyed by the fire and 2,075 ha (5,127 acres) have burned.

Two fires burned together to become the large fire that spread to the suburbs of Christchurch. One was started by an electrical problem and the other originated at a car park. Officials are not speculating as to whether the causes are suspicious.

Approximately 400 homes have been evacuated affecting about 1,000 residents.


A large wildfire is burning in the suburbs of Christchurch, New Zealand in the Port Hills area. As of Wednesday morning U.S. time it had blackened 4,571 acres (1,850 Ha), destroyed an uncertain number of homes, and required the evacuation of approximately 1,000 residents.

On February 14 a helicopter pilot, David Steven Askin, was killed while working on the fire.

Below is an excerpt from an article at nzherald.co.nz:

Christchurch mayor Lianne Dalziel has told Newstalk ZB’s Mike Hosking that she was “very worried” for Christchurch.

“We’ve been going through what’s happened overnight, obviously there’s been more evacuations so we’re looking at 450 properties approximately that have been officially evacuated, with police doorknocking and the army in support as well, so it is very serious.”

She said people have been reporting seeing the fire very close to their properties near Port Hills.

“It looks as if up to seven properties have been affected by the fire, it’s difficult to say until light arrives to get a full handle on how many properties that have been destroyed.”

Dalziel said the blaze was a “difficult fire”.

“We had two seperate fires, one that started in the Selwyn district, managed as a significant rural fire, then fire erupted on the city side, ultimately the worst fears were realised and the two fires came together yesterday.

“It is close to areas of population.”

The weather forecast for Christchurch on Thursday (Wednesday U.S. time) predicts cooler temperatures in the high 60s F, relative humidity in the high 40s, and winds out of the east-northeast at 3 to 6 mph in the morning increasing to 16 mph in the afternoon.

In 2011 an earthquake centered 6 miles southeast of Christchurch caused widespread damage in the city and killed 185 people.

“Experts” defend hunter accused of starting fire when bullet struck a rock

A controversy is brewing in New Zealand about the ability of a bullet to start a fire when it strikes a rock. Below is an excerpt from an article at TVNZ.co.NZ:

Experts on fires and firearms are offering to help a Dunedin hunter fight the Otago Rural Fire Authority which is fining him over a bushfire. Tom Dodds has been accused of starting the fire, which he called in, and he’s been charged more than $60,000 by the fire authority for the cost of putting it out.

Seven Sharp reported earlier in the week that the fire investigator believes Mr Dodds’ bullet ricocheted off a rock, bounced 80 metres and hit another rock, which caused the fire 45  minutes later.

The programme reported last night it has received a lot of feedback on the case, including expert opinions from fire and firearms investigators.

One was straight to the point, calling the authority’s version of events impossible. Another, with 40 years experience, had never heard of a bullet causing a fire.

Causing a fire 45 minutes later is difficult to comprehend unless it was smoldering before it was detected.

It is a fact, however, that it is possible for a bullet striking an object to ignite a fire. We covered research on this topic in December, 2013:

…This research shows that fires can be ignited by hot fragments of the bullets due to the heat generated when the kinetic energy of the lead, copper, or steel is transformed to thermal energy by plastic deformation and fracturing from the high-strain rates during impact…

Coincidence or not, on Thursday the National Interagency Fire Center in the U.S. distributed this tweet:

In the New Zealand case, it’s probably not sparks from the rock that created a problem, but hot metal from the bullet itself that may have started the fire. It is possible that when the bullet hit the first rock, hot metal fragments were created which flew 80 meters and landed in flammable material. A second rock may not have played a significant part.

Firefighters from New Zealand and Australia to assist with wildfires in the U.S.

The National Interagency Fire Center in Boise, Idaho is mobilizing firefighters from Australia and New Zealand to assist with wildfire suppression efforts in the western United States. The two countries have been key partners with the U.S. fire community for more than 50 years but were last mobilized in 2008 when heavy fire activity was similar to this year.

The National Multi-Agency Coordinating Group requested 71 fire managers and specialists.  Although final details of the arrangement are still being worked out, the contingent from Australia and New Zealand is expected to arrive in Boise on August 23 for a one-day induction to learn about current fire behavior, fuels, and weather conditions. Upon completion of the orientation, they will be assigned to large fires.

The request includes 15 Division Supervisors; 15 Task Force/Strike Team Leaders; 15 Helicopter Managers; 10 Heavy Equipment Bosses; 10 Safety Officers; 4 Regional Liaison Officers; and two National Liaison Officers.  Fifteen of the total are from New Zealand. Assistance from Australia and New Zealand is a good fit primarily because their fire organizations are very similar to the United States national fire organization in training requirements and structure.

New Zealand: wildfire at military rifle range

A grenade is the suspected cause of a fire that began at a New Zealand Defence Force rifle range near West Melton on Wednesday. The military was conducting a grenade exercise when the fire started on a warm, dry day with very strong winds. In the video below, which shows helicopters dropping on the fire, the winds appear to be blowing at 20 to 25 mph, at least. In spite of the winds and the rapidly moving fire, you can see a group of 10 to 15 people engaged in some type of activity very close to the fire, which burned 50 hectares (123 acres).

On Tuesday another fire was started by military personnel near Waiouru. In that case it was Singaporean soldiers using live ammunition during a training exercise. It was contained Tuesday night after burning 350 hectares (864 acres) of brush.
