A Hamilton man has admitted assaulting his ex-girlfriend at her workplace and sending her a threatening voicemail message.

Magistrates’ Court heard today that Kishauni Wolffe, 31, had tried to rekindle his relationship with Danielle Foley, after they split in 2013.

However when she rebuffed his advances, the defendant grew agitated. He began phoning her at 6am on August 9, but the complainant did not answer his calls.

Later that morning, when she arrived for work at her office on Parliament Street, Ms Foley saw the defendant standing outside.

Wolffe then followed her into the building and urged her to come outside so they could talk.

When she refused, he became angry — grabbing her wrist through a Plexiglas window and trying to climb over the counter to confront her.

Eventually, Wolffe managed to grab Ms Foley’s hair and hit her head against a wall four times.

A colleague heard her screams and interrupted, at which point the defendant told the complainant to “stop lying” and then headed out of the building.

Wolffe called Ms Foley’s phone again after the assault, and left a message saying: “Wait until you knock off. When the f****** time comes, I’ll be back to your f****** job to finish this the f*** off.”

Senior magistrate Juan Wolffe ordered a Social Inquiry Report, a psychological assessment and a violence risk assessment on the defendant — whom he acknowledged may be a distant relative.

He remanded Wolffe into custody and ordered him to return to court for sentencing on December 9.
