The victims of a house explosion may have survived because they were close to the source of the blast, a fire chief says.
Six people were injured in the suspected gas explosion in Northwood, Christchurch this afternoon. One person was in a critical condition, three were stable, one has beentransferred to Middlemore Hospital and the other patient has been discharged.
Fire and Emergency area commander Dave Stackhouse said they were relatively lucky to be close to the centre of the explosion.
"Often with these types of things it's the blast wave that can actually kill people further away from the actual radius of the initial explosion.
"So I guess we are lucky that we are not looking at multiple fatalities here."
"Once we've got the scene safe ... we'll look at what's caused this and carry out an investigation with police and WorkSafe."
Canterbury Metro Commander Superintendent Lane Todd said this evening that cordons and security would remain overnight around 12 homes that were in the immediate area around the explosion. Police were ensuring the residents had a place to stay.
Other residents who were evacuated after the blast were being allowed to return home this evening.
Todd said safety experts were going from house to house within the wider area to make sure the homes were safe to return to.
"We appreciate this has been a difficult day for the approximately 50 residents who had to leave under such traumatic circumstances," he said.
This morning's explosion sent debris flying 100 metres in all directions and left the house looking like "matchsticks".
Belinda Blanchfield told Stuff four members of her family and a family friend were inside the home at the time.
The explosion was "our worst nightmare", she said.
Blanchfield's husband Paddy told Stuff there had been problems with gas earlier this week and the family were waiting for repair work to be carried out. He was not sure if that work had happened.
In all, 50 residents were evacuated and taken to the Styxx Mill country club immediately after the explosion.

Country Club employee Tom White said concrete tiles from the roof of the exploded house had been blown 100m in every direction.
"The house is matchsticks. It's totally blown apart."
"It's caused a lot of destruction to other houses, it's blown the garage door right off the next-door neighbour's house."

I don't often post here but anyone else in christchurch here a loud, sonic boom kind of noise a few moments ago? the building here shook!!
"The house where the explosion was - you wouldn't even recognise it as a house now.
"I think there are definitely some injuries. They got them out [of the house] but it could be serious."
Maria Lee heard the boom in Burwood, about 15 minutes away from Northwood.
"It was like a sonic boom, a massive boom," she said.
"Our dog just about crapped himself."
Newstalk ZB Christchurch host Chris Lynch says callers from across the city say they heard an explosion. Some residents in Redwood said their houses shook violently.
