An adult entertainer and former Hamilton mayoral candidate has been found guilty of assaulting a man who later punched her teeth out.

Lisa Lewis yesterday failed to defend a charge of assault in Hamilton District Court, stemming from an incident at a party held at her Cambridge home on September 17 last year.

She was remanded on bail by Judge Heather Simpson, and will be sentenced later this month. She is expected to apply for a discharge without conviction.

Lewis - now Lisa Cocker - punched a guest at a housewarming party in the home she shared with then-fiance Drew Cocker. The guest then assaulted her in retaliation.

That man - who has permanent name suppression - was sentenced last November for punching her in the face.

The 39-year-old was convicted and ordered to pay $300 in reparation.

Lewis became emotional during yesterday's hearing claiming she didn't "point at, punch or touch anyone".

She said she was emotional at the time of the assault because Mr Cocker's mother, Sylvia Cocker, had given her son a card that said she loved him, but would not support his relationship with Lewis.

"It was my home and I wanted those people [Mr Cocker's extended family] to leave."

But she was "100 per cent sure" she didn't assault anyone and that she was the victim.

She denied hitting the man first - despite several witnesses telling Judge Simpson that was what they'd seen happen.

"He punched me with a closed fist and punched my teeth out. The photos don't lie."

But the witnesses said it was Lewis who initiated the incident.

Several of them told the judge that Lewis approached Fiona and John Scott [extended family members of Mr Cocker] and asked them why they were at the party if they didn't like her.

They said Lewis was yelling at Mrs Scott and pointing her finger at her chest, before she began doing the same to Mr Scott.

When Mr Cocker realised what was happening, he grabbed Lewis around the waist and took her to the footpath.

But the witness's said Lewis ran back toward the victim, swinging. They said at least one punch connected.

It was then the man hit back with a closed fist at Lewis. They all said they couldn't see any serious injuries to Lewis's face straight after the assault.

The alleged victim yesterday told the court Lewis hit him with "girl-like punches".
