Billie Eilish concert warning: Tickets bought from unauthorised sellers don't ensure entry

Kiwi fans of pop star Billie Eilish are being warned their tickets might not allow entry to her Auckland concert, if they weren't bought from the right place.

The 'Lovely' singer is performing at a sold out, all-ages Spark Arena show on Wednesday night as part of her When We All Fall Asleep World Tour.

Concertgoers and live sport fans are often targeted by scalpers who use resale websites like Viagogo to make a profit off the popularity of live events.

While scalping is a problem the live entertainment industry and the New Zealand government is trying cracking down on, the practice has also seen an upsurge in the selling of fake tickets.

Promoters of Billie Eilish's concert have issued a warning to potential victims - especially to parents of younger fans.

"While we strongly discourage it, we anticipate that some fans will have purchased tickets from outlets other than the official partner [Ticketmaster]. If this is the case, and you purchased tickets from an unauthorised vendor, there is a chance that your tickets may be fraudulent or invalid," says Chugg Entertainment and Laneway Presents.

"Invalid tickets will not allow entry to the concert and cannot be replaced or exchanged for valid tickets.

"As this can often not be determined until the patron is entering the venue, we strongly advise parents who have purchased tickets from unauthorised outlets to wait until their children have successfully entered the venue before departing the area."

Billie Eilish's Spark Arena show is scheduled to start at 8pm on Wednesday.
