"At some point she was able to escape during the attack."
Someone found her soon after on some farmland nearby in a state of distress, Loughrin said.
The woman was able to give the police information about the car and within an hour two young officers stopped a car of that description and spoke to its driver.
Loughrin said the man gave the officers "key features" which led to his arrest.
A 50-year-old Hamilton man appeared in Hamilton District Court and was granted interim name suppression. He will reappear in March.
Loughrin commended the "quick work" of the young officers who were able to "get a really quick resolution to a really horrendous crime".
The woman is being supported by police and other agencies, he said.
