At the time of the assault the couple had two children together and Kemp was pregnant with their third child.

According to the police summary of facts, also released to the Herald by the Manukau District Court, the assault happened in April 2016.

In June 2015, Wilson was granted a final protection order against Kemp, however the pair continued to see each other.

At 12.30pm on Sunday, April 2 last year, Kemp and Wilson were in a carpark at a Papatoetoe swimming pool when they had an argument.

"The couple argued about a minor matter and this escalated quickly to yelling and swearing," the summary of facts stated.

"(Kemp) became enraged when the victim attempted to drive off in the van they had arrived in.

"She grabbed him and began punching him in the arm and pulling him trying to get him out of the van."

Wilson pushed Kemp away, police said, and she then started unloading items out of the van.


Wilson got out of the van and started to put the items back into the van, and Kemp started to punch him again.

She hit him "with an uppercut to the body area" and Wilson punched and pushed her back to get her away from him.

Police said the pair "grappled" for about a minute.

A member of the public called police and Kemp was arrested and charged.

She initially pleaded not guilty to charges of assault and contravening a protection order and was scheduled to go on trial today.

However, when Kemp appeared today police withdrew the protection order charge and Kemp changed her plea to guilty for the assault.

A third charge of failing to appear in court was also admitted and Kemp was convicted and discharged.

Judge Philip Recordon sentenced Kemp to 12 months' supervision and ordered her to complete a parenting help course "with an anger management component".

He also ordered her to complete any other course or programme her probation officer directed.

Recordon said it was not the first time Kemp had been before he courts for assaulting Wilson.

Police said Wilson was also on active charges for violent offending against Kemp, and was scheduled to appear in the Manukau District Court later this year.

Wilson did not speak to police after last the Papatoetoe incident and was "disinterested" in the prosecution, the court heard.

He did not submit a victim impact statement.
