A tradesman who was driving past the Masjid Al Noor mosque where a gunman opened fire on hundreds of people inside has described the horrific scene that unfolded in front of them.

Carl Pomare told Radio New Zealand he saw “people running for their lives” and heard “rapid fire” from a semiautomatic weapon that sounded like fireworks going off.

“We saw these people hit the ground, they were being shot in front of us,” he said.

Mr. Pomare said he and others from Naki Labour Hire drove 100m up the road and formed a cordon at the southern end of Deans Avenue so other people could not enter the street before rushing straight to the victims to help.

He said with it taking 10 to 15 minutes for emergency services to arrive they had to spring into action.

“We saw them being shot. Being mowed down as they were running away,” he told Newstalk ZB.

“I said to my mate, ‘We need to do something’.”

He said they were nursing victims on the footpath amid the “absolute carnage”.

“There was one little girl, probably about five, she’d been shot, and her father,” he said.

“We managed to get the five-year-old on the back of one of the vehicles before the ambulance came, she was critical.

“We looked at it thinking we’ve got to get this little girl to the hospital now otherwise she’s going to die.

“My worker was nursing a guy who had been shot in the back three times for about half an hour, saying, ‘Hang in there buddy’. He passed away in my his arms.”

The contractors stayed for more than an hour, even when the shooter was still at large.

“The shooter came out chasing people running away,” he said.

“While my worker was nursing one of the victims there was more shots inside the mosque. It was a pretty scary situation because there were still other shots being fired at the time inside the mosque.

“We were very vulnerable but in a situation like that you don’t think about yourself.”

People who heard his interviews on social media described the men’s efforts as “incredible”.
