Johannesburg - The trial of former modelling boss Dawie de Villiers was postponed in the High Court sitting in Palm Ridge on Friday.
De Villiers faces 38 charges in total, including rape and sexual assault.
His lawyer, Jaques Pienaar, told the court his instructing attorney, Riaan Louw, was absent from court because of "dire personal reasons". Continuing without him would put the defence team at a disadvantage, as a new witness was set to take stand.
Judge Cassim Moosa agreed and postponed the matter to October 13.
De Villiers faces one count of indecent assault, one count of rape, two counts of exposing pornographic materials to two minors, two counts of sexual grooming, one count of intimidation, seven counts of sexual assault, two counts of possession of pornographic material, eight counts of accessing child pornography, three counts of crimen injuria and 11 counts of fraud.
He has pleaded not guilty to all the charges.
The 35-year-old is accused of among others, raping a 15-year-old girl in 2011. He then allegedly asked the teenager to have a relationship with him and to send him a picture of her private parts.
He is also accused of indecent assault after he penetrated an adult female from behind against her will.
In the same year, he also allegedly inserted his fingers under a 14-year-old's ski pants. Thereafter, he allegedly told the girl she sexually aroused him and requested she send him pictures of herself naked or wearing lingerie.
He also then sent her naked pictures of himself, the court heard this week.
In a separate incident, he is accused of inserting his fingers inside a 15-year-old's underwear and kissing her on the mouth.
De Villiers also faces charges of exposing pornography to two children aged 7 and 10.
