Sold-out tickets to boy band One Direction's concerts are selling in online auctions for more than four times their face value.
But some Trade Me users are fighting back against the large profits and are sabotaging the auctions by placing large, "silly" bids with no intention of paying.
One mother of a disappointed 12-year-old girl who missed out on a ticket has questioned whether it's fair that reselling Rugby World Cup tickets was illegal but reselling One Direction tickets is not.
The $92 tickets for the three April shows in Auckland and Wellington sold out in minutes but within hours some had been listed on Trade Me. The bids have sky-rocketed as more tickets were listed. Last night there were almost 40 listings, with pairs of tickets costing as much as $735.
Some Trade Me users, angry at people making such a large profit from tickets for a tween concert, have been hijacking auctions.
