Twenty-one prostitutes have been found working illegally in Auckland brothels raided by Immigration NZ officials since the Rugby World Cup.
"Eight brothels have been visited to check for people who may be working contrary to their visa conditions and to remind premise operators of their obligations to ensure compliance with immigration law," said Immigration's acting general manager for intelligence, risk and integrity, Peter Elms.
At one Auckland brothel, Emily's 8, four prostitutes were found to be working illegally. They included one Malaysian who was on a student visa.
The brothel, in Waverley St, has been issued a warning letter.
The Herald understands another Auckland brothel, which last year withheld the passport of a Malaysian sex worker, was also raided.
