Going, going, gone - a New Zealand teenager has auctioned off her virginity to a stranger for over $45,000 to fund her university tuition fees.

The 19-year-old Northland student, who listed her virginity on the ineed.co.nz website under the name `Unigirl', said the leading bid was "way beyond what I dreamed".

"Thank you to the more than 30,000 people who viewed my ad and to the more than 1200 offers made," she posted on the site.

New Zealand's leading online auction site, Trade Me, said it would not allow such a listing.

But ineed.co.nz has defended the listing, saying it was legal and the site did not place moral judgments on its members.
