A Christchurch couple recounted the moments they pulled five injured people from a Christchurch house after it exploded this morning.
Brad and Megan Culver, who live directly behind the house that exploded, were at home when it happened.
Their own home, which they rent, has significant damage.
Fire and Emergency New Zealand says one house is destroyed, five are "severely affected" and 17 others impacted by debris. The blaze is now contained.
"Everything in our house just sort of exploded, glass, everything," Megan said. "Very devastating. I've never really experienced anything like this."
Brad added that the lights came down and the roof lifted up.
"I thought that a plane had crashed and exploded behind our house," he said. "All the surrounding houses around it are all just completely destroyed.
"Once I knew Megan was okay I ran out to assess what was going on and saw the smoke coming up behind us.
"The house [which exploded] was in a complete pile of timber, and rubbish. You couldn't even conceive that it was a house, there was nothing left standing."
Brad said they started pulling people out of the ruins - five people, he'd been told. "We got all five of them out before the emergency services came."
He said they were in shock.
"A real tragedy, again in Christchurch," Brad said.
