Andrew Ahlfeld, 36, appeared in the Dunedin District Court last month and was jailed for two years eight months.
In January, a jury found him guilty of two charges of indecent assault, sexual violation by unlawful sexual connection and assaulting a female.
The jury heard that on September 3, 2022, Ahlfeld was in the Westland National Park with a group of people on a tramping trip.
That night, he groped a sleeping woman over her sleeping bag.
She awoke, and when she sat up he touched her again.
The woman said after she gave Ahlfeld a "stern look", he apologised and left.
The second woman was chased down by Ahlfeld before he grabbed her and asked for a kiss.
She declined and continued walking, but he held her again and tried to kiss her.
Ahlfeld pinned her against a wall and "suddenly and forcefully" violated her with his fingers.
She escaped his grip, but Ahlfeld got hold of her and tried to kiss her again.
Counsel Sarah Saunderson-Warner told the jury her client never touched the sleeping woman and only consensually kissed the other.
She said her client thought he had a "fun-filled trip", which he never thought would result in charges and a trial.
But the jury rejected Ahlfeld’s narrative and instead believed the two women.
At sentencing, the victim said she
hoped the defendant would receive a sentence that would help him reflect on the harm he caused and give him the help he needed.
Crown prosecutor Craig Power highlighted the woman was "virtually a stranger" to Ahlfeld and was vulnerable.
"She’s a woman alone, walking along the track at night in the dark.
"If that’s not vulnerable, what is?" Mr Power said.
The other victim was also vulnerable as she was sleeping when Ahlfeld assaulted her, Mr Power said.
Ms Saunderson-Warner reminded the court one victim did not want charges laid in relation to the assault on her.
"You have an intelligent young woman saying that she wasn’t fazed by it," Ms Saunderson-Warner said.
Judge Michael Turner called the sex crimes "impulsive, predatory behaviour".
"You would not take no for an answer."
The judge questioned why the man defended the charges given he was highly intoxicated and had little memory of the night.
"You were out of it that night and really were in no position to say if the offending happened or not," the judge said.
"You are now genuinely contrite for your behaviour."
Along with the prison term, Judge Turner ordered Ahlfeld to pay $10,000 emotional harm reparation to the victim of the sexual violation.
