A drunk 15-year-old became so nervous before her first job as a prostitute that she vomited, leaving her annoyed young girlfriend to do the job, a New Plymouth District Court jury trial was told yesterday.

Michael Hastie, 60, has denied a raft of underage prostitution charges relating to the two teenage girls and supplying them both with cannabis.

The Crown alleges Hastie lured the first 15-year-old to New Plymouth by pretending to be a 22-year-old surfer.

Hastie, in fact, ran an escort service, and employed the 15-year-old runaway as a prostitute after first having sex with her, it is alleged.

Yesterday a 20-year-old young woman gave a colourful account of her time staying with her friend at Hastie's Westown home during the school holidays in 2006.

She described how they had smoked cannabis supplied by Hastie at least three or four times a day.

They would also go to a nearby bar, the Nag'n Noggin to drink with Hastie and the owner.

Over the time she stayed, she met Hastie's prostitutes who either worked from the spare room or did "outwork".

One was a "fat chick" whose name she could not remember.

"Mike said you have to have a fat chick because some people like them," she told the court.

While she was in New Plymouth, her prostitute girlfriend ran out of money and the two went with Hastie into the Taranaki Daily News office to place an advertisement for her under her working name.

Hastie said: "The boys will be ringing straight away, they love you."

She said she decided she too would like to try being a prostitute.

"I thought this could be easy money. It couldn't be hard, could it?"

Hastie showed her a video about prostitution, asked her if she knew about condoms, and told a client "I've got this new girl", described her and booked him for her first job.

"I thought, sweet, I'm going to get some money."

When the client arrived, Hastie had said, "That's you, you're up."

She was "pretty drunk" but had a shower, then became flustered and thought: "I'm going to be sick. I was dry-retching into the toilet. I said, I can't do this."

Her young friend had arrived home and she confessed she could not go through with it.

"She was pretty pissed off with me, so she did it. He was booked for an hour but she would only do it for half an hour. She was really shitty about it. I sat in the lounge and drank."

Earlier during cross-examination of the runaway, Hasties' defence counsel Susan Hughes QC, said the girl was "simply being mischievous" when she said she and Hastie had sex because he had heart problems and was impotent.

"I didn't know. I've got no reason to lie," the girl said.

"You have cast yourself in the role of victim," Ms Hughes said.

"I am a victim," she replied forcefully.

"Mr Hastie never supplied you with cannabis," Ms Hughes said.

"He did."

The complainant acknowledged she had been addicted to methamphetamine while in Auckland in 2006 "but I got myself off it".

"You have never worked as a prostitute," Ms Hughes said.

"Yes I have."

The trial continues today.
