Scalpers don't miss a beat in a bid to sell Fleetwood Mac tickets

Minutes after the Dunedin Fleetwood Mac concert sold out, scalpers started listing tickets online.

But a concerned promoter says fans should refuse to pay the inflated prices as tickets can be secured other ways.

The concert on November 18 sold out in less than an hour of going on full public sale on Wednesday.

A auction for a pair of tickets worth $398 had a bid of more than $600 when it closed yesterday.

A similar listing fetched a similar bid.

Another pair of tickets worth about $600 had a bid of more than $1200 when the auction closed yesterday.

Live Nation Australasia chief executive Michael Coppel said scalpers taking advantage of fans by extorting inflated prices for tickets was a concern.

Tickets were still available to American Express card holders at standard prices, and limited VIP package were available.

"There is no need to go to a scalper to secure your ticket," Mr Coppel said.

The entertainment company was working to make more tickets available for the only South Island show and hoped to have "good news" to announce in a couple of weeks.

Trade Me trust and safety head Jon Duffy said the reselling of concert tickets was legal.

A Live Nation spokeswoman said more than 28,000 tickets had sold for the Dunedin concert and a second Dunedin show was unlikely.

TicketDirect chief executive Matthew Davey said he was "stocked" the Dunedin-based ticketing service could help get the event to the city.

He apologised for a "glitch" delaying the presale on Monday by an hour.

The presale tickets sold fast and the "last handful of tickets" sold on Wednesday was a great result and "bodes well" for other big events coming to Dunedin, Mr Davey said.
