More than 23,000 pre-sale tickets to Elton John's Mission Estate show have sold out in less than an hour.
Pre-sale tickets went live online on the Mission's website at 9am, with users reporting that more than 30,000 were in the queue.
By 10.05am the pre-sale tickets were sold out. Nearly 23,500 tickets had been sold, a Mission spokesman said. The winery venue's capacity is roughly 26,000.
Many fans on social media complained about the system, claiming they were in the process of purchasing tickets before being pushed to the back of the queue.
Some of the dozens of complaints on Mission Estates Facebook page.
Mission Estate CEO Peter Holley said no formal complaints had been laid with it as at 11am.
"At this moment in time no formal complaints have been made regarding the system, but we will have our IT department look into it," said Holley.
One fan, Jacqui Robinson, found the system to be "extremely poor" for a concert of such significance to so many.
"Mission Estate really needs to clean up their act when it comes to these things if they want to be able to host big acts like this."
Robinson logged on fifteen minutes before the tickets went on sale, having already signed up as a member and was listed 1083 in the queue.
But as she went on to the next stage to pay for tickets the system failed multiple times.
"As I went to go pay for my tickets the page kept on saying error wait till we redirect you, then on the third time it told me I was number 27,000 in the queue.
"It was just annoying to have to wait that long and then get pushed to the back," said Robinson.
Some fans have also turned to Twitter trying get a second concert organised for those who missed out.
For Robinson it's a lost opportunity for a once in a lifetime experience.
"My husband and I saw him perform at Wembley in 1992 which was an amazing experience and being British expats we wanted to see him one last time on his big farewell tour, but now we probably won't be."
Elton will be performing at Mission Estate on February 8 next year as part of his Farewell Yellow Brick Road world tour. He will also play in Auckland and Dunedin.
