"There was still kerfuffle going on there and another guy ran past me going like the clappers " he couldn't get past me fast enough " and I said, 'what the hell are you little bastards up to?' as he ran past me," the woman, who wanted to protect her identity, said.
"And then I saw there were two guys (further down the road) and one was trying to get one off the ground. They tried and tried to get him up. I thought, 'At least somebody's with him so they can call whoever for help.' So, I didn't run to help in case there was more trouble."
The stabbed officer was taken to Kaitaia Hospital then on to Whangarei Hospital, where he was discharged yesterday morning. Police were still searching for the main offender at edition time yesterday, though one of his alleged associates, was arrested at a nearby house and charged with unlawfully getting into a vehicle.
Mr O'Connor, who has pushed for a broader arming of police, said the element of the unknown could catch out "even the most experienced officer".
"The reality is that, however well prepared police are, we deal with violent unpredictable people that the best preparations will not protect from ... Especially where the incident arises from a routine piece of policing - as this one did."
He said, while some frontline officers wore stab-proof vests, they only covered torsos.
"We are reminded that these things can arise out of nothing," he said, and urged the officer not to blame himself. "The officers often relive these things and think what they could've done differently. Usually there's not much. They had no choice but do what they were doing."
He described the Kaitaia incident as "a fairly traumatic way to end the shift".
Northland police would not provide further details on the nature of the officer's injuries and when he would be back at work, but said he would receive ongoing support.
Waitai Miru, 17 appeared in the Kaitaia District Court yesterday charged with unlawfully getting into a motor vehicle. He was remanded in custody to re-appear on December 16.
