The story prompted a Wanganui woman, who had a similar experience at age 17, to come forward. She said rape happened everywhere, and a lot more often than people thought.
"It's important that when people see stories like this they don't think those girls are stupid and it only happens in South Auckland."
Even now, in her forties, she still feels shame, as if it was her fault, and she was briefly in tears as she talked to the Chronicle about it.
"I would never want my mother to know, because it would break her little heart."
She said she was a confident, capable person when she was 17 and still is.
"I just fear for those young women and girls who don't have the support and self-belief to get through it."
She didn't make a complaint in the late 1980s when she was raped and said she would probably make the same decision now.
"Even if he went to court and he was convicted, I would end up being a greater loser."
She'd like to see the "victim-blaming mentality" in rape cases end. The blame should be with "the guy that takes advantage of a girl that's semi-conscious or even unconscious".
The woman didn't want to give her name.
She was still at secondary school when the rape happened. She said she was a good student, but used to party hard. She had been drinking heavily on weekends since the age of about 15, and had become semi-conscious at times. She had also smoked cannabis at parties occasionally.
She and about 10 middle-class friends, mainly from Wanganui, were spending a weekend at the Taupo house of one of their parents while the parents were away.
On Saturday night they drank a lot and smoked cannabis. She said she got "pretty wasted" and found herself kissing a Wanganui school seventh-form boy.
The next thing she remembered was being in a bedroom with him - she doesn't even know how she got there.
She didn't want to have sex, and remembers saying no, but didn't leave, scream or push him away.
"I couldn't really move because I was so out of it."
It was the first time she had ever had sex, and she didn't enjoy it. The next morning she was hungover and laughed it off.
She didn't tell anyone about the rape until seeing a counsellor years later.
Women couldn't consent to sex if they were too drunk or stoned to walk, she said. She wants the police to act against the "Roast Busters" group.
