"Nikolas takes full responsibility for his actions that night," it says.
"He attended a restorative justice conference where he expressed his remorse, and he again apologises to the police officer, university security guard and all others concerned.
"Nikolas was in the first two months of his university study away from home in Dunedin.
"He made a bad decision in the heat of the moment which caused considerable harm to those affected, which he regrets.
"He also apologises to his family and those around him for the trouble he has caused them."
Earlier today, Acting Area Commander Otago Coastal Inspector Kelvin Lloyd released a statement which said Kane would not be making any comment on the case.
"Any assault on our staff is a concern and we continue to offer Constable Kane the necessary help and support she needs in her recovery," Lloyd said.
"While operational policing always carries an element of risk, our staff do not go to work expecting to be assaulted.
"Constable Kane is very grateful for the support and concern that members of the public have expressed to her."
Kane's focus is now on returning to work and she asks for privacy at this time, Lloyd said.
Delegat is the son of Jakov "Jim" Delegat and wife Kate. The National Business Review listed Jim Delegat and sister Rosemari's wealth at $350 million in last year's Rich List.
Delegat fought to keep his name from the public, beginning with an application filed in the Auckland District Court last May.
That bid was quashed by the Court of Appeal in November.
Delegat was initially charged with the aggravated assault of Kane, assaulting a campus watch officer, resisting police and intentionally damaging a window.
As a result of the assault on her, Kane needed hospital treatment for a black eye and serious swelling to her face.
That charge was amended to assaulting a police officer with intent to obstruct her in the execution of her duty earlier this year.
He admitted to resisting arrest last year, but did not plead guilty to the other charges until June this year.
He yesterday applied for a discharge without conviction.
In sentencing the 19-year-old, Judge Kevin Phillips said he would not grant a discharge without conviction as Delegat assaulted two people without "any real degree of warning or provocation".
He punched Kane with such force as to render her unconscious and then delivered three further blows.
Her injuries resulted in concussion and 15 hours of hospital treatment.
She still suffered from ongoing headaches, Judge Phillips said.
A summary of facts said Delegat punched a hole in a window after he became very angry about a remark made by a friend about his girlfriend.
He then punched a Campus Watch officer who intervened during a heated argument between Delegat and his girlfriend and violently resisted police, punching Kane in the face as she was trying to arrest him.
