Arriving from Beijing last week, Celeste Zhang claimed airport authorities separated her and a female travel companion and questioned them for about half an hour about their reasons for coming.
Miss Zhang, 23, a nursing graduate, and her friend, who did not want to be named, said they were offended that immigration officials at the airport had suggested they could be here to look for work in the sex industry.
Figures released by Statistics New Zealand yesterday showed a boom in tourists from China helped boost visitor numbers to New Zealand by 11 per cent in March compared with the same month last year. Visitors from China were up 8700, the second highest monthly increase for tourists from that country.
Auckland-based Chinese tour operator Chris Li said single Chinese women were often held up at the airport and viewed suspiciously when they arrived here. He said they often took about 45 minutes longer to be processed.
However, Immigration NZ said it did not treat incoming single Chinese female travellers differently.
