Psychologist charged with historical sexual offences against young men

Ban Teik Tan, also known as Ricki Tan, is facing 17 charges of historic sexual offending. The charges involve five complainants and include indecent assault and unlawful sexual connection with a boy aged between 12 and 16. Tan has pleaded not guilty to all charges.

The alleged offending occurred between 1996 and 2005, though one report states the period spans from the late 1980s to the early 2000s. Tan, a 63-year-old registered psychologist since 1995, has had his practising certificate suspended.

Police are investigating whether there are more victims, noting Tan had professional involvement with more than 100 young people through agencies such as Oranga Tamariki and the Youth Court. Detective Senior Sergeant Colin Baillie said police have already contacted 90 people known to have had contact with Tan.

Tan's name was released after he abandoned an appeal against a decision to deny him name suppression. In a statement, Tan said, "I absolutely deny those allegations. I am innocent".
