Seventeen people arrested for human trafficking appeared in the Durban Magistrate's Court on Monday, said KwaZulu-Natal police.
Their case was postponed to Tuesday for the court to get an interpreter, said Major Thulani Zwane.
The group was arrested on Thursday when police raided a house in Grosvenor Crescent in Greenwood Park, north of Durban.
Fourteen Thai women aged between 20 and 26, who were allegedly being used for the sex trade, were found in the house, said Zwane.
"It was discovered that 12 of the women are in South Africa illegally. However, it is still yet to be determined if they were being kept here against their will," Zwane said.
Three South African men also found in the house were arrested.
Two of them were believed to have been clients while the other, a 62-year-old, was alleged to have been running the business.
