A New Zealand consumer watchdog is joining forces with international groups to investigate the growing problems people have buying tickets through reselling sites.
Consumer NZ and consumer groups in Australia and the UK are investigating complaints about ticket sites such as Viagogo and Ticketmaster Resale.
Chief executive Sue Chetwin said complaints about ticket resellers have been on the rise in New Zealand and overseas.
"We've heard reports of tickets being sold on resale sites in New Zealand for up to 20 times their face value. Customers also routinely report being stung by steep fees on these sites."
In a recent case an Auckland woman paid $1000 for VIP tickets to see British songstress Adele only to find she'd been sold stall seats worth $100.
