A rich Auckland businessman and a young woman who acted as his teenage pimp have been found guilty by a jury.

The 52-year-old man has been convicted on 16 charges covering a range of drug and sex offences.

His 20-year-old associate was convicted of inducing girls to have sex with the man with the promise of drugs.

After the jury deliberated for a day, the pair were acquitted on two counts which alleged they intentionally stupefied young girls using illicit drugs.

Both have name suppression.
