He was found not guilty of another indecent assault between March 1 and April 6 when he was accused of grabbing the young woman's breasts.
The man was discharged during the trial on one sexual violation charge alleging unlawful sexual connection with a third woman, aged about 40, at a Balclutha toilet on April 11, 2012.
However, he was found guilty of raping her in the toilet on the same night and raping her again near a church at Pukerau later in the night.
The defence case was none of the incidents happened, although the man said he had sex with the third victim, with her consent, at Port Chalmers, several hours before giving her a ride to Gore, when she said he raped her. Scientific evidence identified his semen on swabs taken from that woman.
Crown counsel Craig Power and Sarah Saunderson-Warner put their closing arguments to the jury on Thursday afternoon and Judge Crosbie summed up the case yesterday before asking the jury to reach a verdict.
He reminded the jurors an accused person had to be presumed innocent and the Crown must prove the charges. The accused did not have to prove anything.
