Judge Jim Large adjourned briefly for counsel to discuss the matter.
When he returned to the court, prosecutor Sergeant Chris George said he had spoken to the district prosecutions manager about the case.
More than a year after the charge was laid, and after multiple appearances in court, police offered the high-profile medical professional diversion.
George said that had the matter gone to trial the prosecution case would have been that the defendant had used "excessive self-defence" during the incident at the start of 2019.
The victim, who was in the courthouse on Monday, was happy with the outcome, George told the court.
The couple had broken up after the violent incident and the woman was not interested in obtaining a protection order.
Despite no suppression orders previously being imposed by the court, George requested the defendant's and victim's names be kept under wraps, to protect the woman involved.
She did not have the same surname as her ex-partner, nor were they from a small community where the case might face extra scrutiny, it was confirmed.
Judge Large asked the Otago Daily Times whether there was an intention to report on the case.
When the newspaper refused to state a definitive position, the judge said: "I'll make the decision for you."
All details leading to the identification of the parties were suppressed.
