However, after turning the car around, he again stopped the car and intensified his attack.
When the victim told Tukuafu to stop the assault, he did so and drove her to the end of her road.
Tukuafu, a first-time offender, was caught after his wallet fell from the car and the victim took it to the police.
The Crown did not oppose a home detention sentence and Tukuafu's lawyer Tony Rickard-Simms urged Judge Thomas Ingram to impose such a sentence.
Judge Ingram said: "The seriousness of this assault should not be belittled, and must have been terribly frightening for the victim and a very difficult thing for any young woman to face.
"There may well be some lasting effects for the victim, particularly her ability to trust other men because of what you have done," the judge told Tukuafu.
However, Judge Ingram said having regard to Tukuafu's previous otherwise unblemished record, his remorse, offer to pay $1000 emotional harm to the victim and being assessed a low risk of further offending, he was satisfied the most appropriate sanction was home detention.
