The investigation into a police shooting in Coffs Harbour has found the victim was unarmed.

In the early hours of Tuesday morning a young Victorian woman was shot in the jaw at close range as she sat in the driver's seat of a stolen car near the Coffs CBD.

The head of the Local Area Command Mark Holahan says neither the woman or her male passenger were armed.

"We now know that, after the examination of the crime scene that no other weapons were located, and we know that the lady now is still in a stable condition at John Hunter.

"We know that there were four people at the scene that night.

"Two of those people have been spoken to, and two have not.

"We know now that there was only one shot fired and the officer that had control of that firearm.

"He needs to make a number of assessments with other people to make sure he's psychologically right to continue with his duties," he said.
