A Dunedin doctor's girlfriend was expecting him to visit on the night he's accused of slashing a teen girl's throat.

Venod Skantha, 32, has pleaded not guilty to the murder of 16-year-old Amber-Rose Rush, who was stabbed to death on February 2, 2018.

Skantha's girlfriend - a lawyer - told the court today she'd drawn up some paperwork he needed to sign and that he'd arranged to drive to her Balclutha home to meet her after he finished work.

But she says she didn't hear from him at all that Friday.

"I was pretty annoyed."

The court heard they had a text exchange at around 1am on Saturday morning.

"He said he'd been sleeping - but if it was so important he'd come over now.

"I said I didn't want to see him. 'Don't come - I'm done with you. Done with it. I'll send the paperwork to you on Monday'."

The woman says Skantha turned up to her house around 2.30am.

"He came into the bedroom by himself. Then he said he's got [the young man who claims he drove Skantha to Amber-Rose's house that night] with him because he didn't want to fall asleep while he was driving."

The next morning, she says, Skantha told her he wanted to have a bonfire that day.

There's CCTV footage of them buying kindling supplies and a large terracotta pot at the Warehouse.

The Crown has accused Skantha of using these items to burn his bloody clothes.

The defence has argued that blood found in Skantha's car could've belonged to him.

Today his lawyer, Jonathan Eaton, revealed he went to the emergency room the day after the death - because he'd cut his finger.

Eaton says blood found in his house - on a sword and in the kitchen sink - was shown to belong to him.

Yesterday, the jury heard of a potential blackmail plot by Amber-Rose and her mother, and her final messages before her death.

Minutes before she was stabbed to death she messaged her older sister: "I'm so angry."

Amber-Rose's sister, Shantelle, only noticed the message on the morning of February 3, 2018.

She replied "why?", but, by that time, the teenager was lying dead in her blood-soaked bed after sustaining six wounds to her neck and throat.

The court heard Skantha was also messaging the victim on the night of her death.

Amber-Rose had accused him of indecently assaulting her and "touching up" others. She would go to the police and to Skantha's bosses at the hospital, she told him.

Amber-Rose's boyfriend, Kristin Clark, was also communicating with her on the night she died.

She sent screenshots of her heated exchange with Skantha and Clark said he was concerned she would confront the man.

At 11.53pm, Clark sent her: "I'm willing to do anything for you. I can pick you up."

"I won't be allowed," Amber-Rose replied. It was her last message.

Clark continued to articulate his worry, and when he received no response, he left his Dunedin North home to see her.

He told the court he knocked on Amber-Rose's window in the early hours of February 3.

There was no response.
