"He fired his Taser twice at the man as he ran away," the report said.
"The probes hit the man in the leg and then in the back, however the man pulled them out, with no obvious ill effects, and continued running."
The man was arrested a short time later after a struggle.
A month later the man complained to police about the force used during his arrest.
"He said that he should not have been Tasered and that the probationary constable pushed him down a flight of stairs and then tried to break his arm when he was arrested," the IPCA report stated.
"The authority acknowledges that the probationary constable was inexperienced and was worried the man could run into a house where he could get help, get a weapon or hurt an innocent member of the public," said chairman, Judge Sir David Carruthers.
"However police policy is clear that a Taser can only be used on a person who is assaultive.
"As the man was running away at the time, his behaviour had not met that threshold.
"The officer's use of the Taser clearly breached policy."
The man also claimed that the constable told ambulance paramedics to "knock him out".
But the authority did not uphold that part of the complaint.
"The probationary constable did not dive on the man or push him down the steps or try to break his arm," Sir David said.
"The force used by the officer to handcuff and control the man was reasonable and justified in the circumstances.
"There was no evidence that any officer present directed the ambulance paramedics to knock the man out or sedate him."
Police revealed that during the arrest the offender bit the officer, who needed hospital treatment as a result.
The offender was later convicted on a number of charges, including stealing the car, assaulting police, failing to stop for red and blue flashing lights, driving while forbidden and receiving property and possessing tools for burglary.
Auckland City District Commander Karyn Malthus said police accepted the IPCA finding.
"Officers face making split-second decisions every day and we constantly seek to deliver policing to the high standards we set for ourselves," she said.
"Learnings have been taken from the incident and we accept the findings of the IPCA.
"We have acknowledged that while the officer's actions were not in line with policy, he and the other officers were acting in good faith."
Malthus noted that a number of allegations had not been upheld.
"There was no evidence that any officer present directed the ambulance paramedics to knock the man out or sedate him."
