John Hope Muchirahondo is accused of sexually assaulting at least 15 women at parties and nightclubs between 2009 and 2021 - some multiple times.
It is alleged he filmed many of the assaults he has been charged with.
Muchirahondo has pleaded not guilty to 22 counts of rape, nine of sexual violation by unlawful sexual connection and a further charge of failing to assist police with a search of his computer.
Several of the charges against him are representative.
A representative charge means police believe a person has committed multiple offences of the same type in similar circumstances.
Muchirahondo - born and raised in Zimbabwe - was arrested in February 2021 after he was accused of assaulting four women.
After he appeared in court for the first time, police made the rare move of releasing a statement about the charges, naming Muchirahondo and inviting other potential victims to come forward.
That resulted in the charges relating to the other 11 women.
His trial in the High Court at Christchurch yesterday before Justice Lisa Preston.
After a lengthy jury selection process, the judge addressed the court yesterday afternoon.
She explained the trial process, what the jury could expect over the next two months and outlined their role and responsibilities.
She said it was “vitally important” that jurors kept an open mind until the end of the trial.
“Pay attention but be aware that the evidence is not complete until the final witness has been called,” she said.
Jurors were also reminded they needed to be dispassionate and disregard any feelings of sympathy for or prejudice against anyone in the trial.
“Emotions have no place on this trial... you need to recognise those as they arise and put them to one side,” she said.
“Do not go onto the internet to investigate anything that arises. Do not be tempted to check names, places, identities... anything of that nature that might help you.
“Please do not read or watch material related to this trial. Concentrate on the material, the evidence you hear in this court.”
During that time the jury is expected to hear from 108 Crown witnesses including the complainants, their friends and associates; bar staff, a taxi driver, medical staff, forensic scientists and police.
Photographic and video evidence will also be presented.
The jury has not been told yet whether Muchirahondo will give evidence in his own defence or call his own witnesses.
He is not obliged to do either.
