The woman said she became suicidal and self-harming and had to be put on around-the-clock suicide watch by her family. She rarely slept well, with "terrible nightmares" constantly waking her.
"I thought I was going to die (that night), I thought they were going to kill me," she said.
The woman became pregnant last year, against the odds given a medical condition, but miscarried and blamed the trauma of the rape for that. She said she also believed the rape may have been part of a gang initiation ceremony as she knew Johnstone had gang links.
In mitigation, Lucy Postlewaight, for Johnstone, and John Watson, for Anaru, submitted that the guilty pleas had spared the woman from having to go through the whole trial and be cross-examined. Anaru had also been prepared to give evidence against Johnstone at his trial. Johnstone, meanwhile, had mistakenly believed there was some form of consent from the woman, but pleaded guilty when he realised that was not the case.
Judge John McDonald said the woman had been drinking the night she was raped and had accepted a lift home from Anaru and Johnstone, who was driving, when she met them at the Mobil Service Station on Walton St.
The pair took her to the old railway station and raped her, while Anaru also sexually violated her twice.
Judge McDonald said the men violated the woman for their own sexual gratification and it had affected the woman appallingly.
"It's all but destroyed her life," the judge said.
"There are some in our community who wold say she brought this upon herself by going into town and drinking. Anybody who thinks like that should be ashamed of themselves. A civilised society, that we claim to live in, is supposed to protect all of its citizens, not through the use of the police only, but with each person in that society helping and protecting others. That's what she thought (Johnstone and Anaru) were doing that night (when they offered her a life home).
Judge McDonald said a starting point for the pair was 11 years' jail, but he gave them credit for their guilty pleas and also gave Anaru extra credit for being prepared to give evidence against Johnstone in the trial.
