A police officer strangled to near unconsciousness could have defended himself if he had a Taser, police say.
The Police Association today said it was unacceptable that lone police officers were still on patrol without weapons to properly defend themselves on their belts.
Association president Greg O'Connor said having weapons in police vehicles wasn't practical in many situations.
"Violent incidents arise before officers can return to their vehicle to retrieve the Taser, so they need to be carrying them," he said.
Police for years now have been calling for senior staff to be able to carry the devices on their belts.
"If the officer had had a Taser, he would have been able to avoid the need to enter into a physical struggle with the offender," Mr O'Connor said.
The attack took place in Counties Manukau around 3pm yesterday after a motorcycle officer got off his bike to chase an offender who had tried to escape a pursuit.
Police say they are reviewing the incident and that the officer sustained minor injuries in the attack. He is now taking "a few well-deserved" days off work.
"He has shown real courage and commitment in apprehending this offender to prevent further risk to others, and his actions should be commended," says Waitemata district commander Superintendent Bill Searle.
Supt Searle says though the injuries were minor, "no assault on our staff is ever acceptable".
"Therefore, as is routine with all critical incidents, we'll be reviewing it to identify whether there are any lessons that can help inform our response to future incidents."
A 41-year-old man has been arrested and charged with aggravated injury, unlawfully using a motor vehicle, failing to stop and dangerous driving.
