Adele's tour boss has warned she "might not be back"

Adele's down under promoter has warned Adele "might not be back" as her record-breaking tour hits Auckland tonight.

The UK singing sensation is set to perform at Mt Smart Supertop tonight, then again on Saturday and Sunday, her first ever shows in New Zealand.

During her recent tour of Australia, she broke records in every city she visited during the eight-concert tour.

Now, tour promoter Michael Coppel has told the Daily Telegraph that this might be the only time the singer makes it here.

"We may never see her again," Coppel said. "Adele's been quoted as saying she won't tour again, she's doing this big tour as a recognition of her huge record sales and the enormous demand to see her live.

"It's impossible to tell what happens next. Then the future's an open book."

The Hello hitmaker sold as many as 600,000 tickets during her record-breaking tour Down Under, which included the biggest single concert ever held on Australian soil in Sydney's ANZ stadium, where she performed in front of 100,000 people.

Coppel said it had become the biggest tour he'd ever worked on.

"It's the highest-selling tour I've ever been involved with, which is quite remarkable after working with Pink and U2 and Fleetwood Mac and Roger Waters."

Adele's show in Perth, Western Australia, was the quickest-selling event in Domain Stadium's history, while her gig at the Adelaide Oval beat the stadium's highest audience attendance record.

In Brisbane, meanwhile, Adele's two concerts attracted a combined crowd of 120,000 - which is a record for music events in the city.

The London-born star also performed in front of 75,000 fans at Etihad Stadium in Melbourne.

Despite being one of the best-selling artists of all time, Adele has admitted she still suffers from stage fright.

The singer-songwriter confessed in 2015 that she was finding it harder to perform on stage and was "too frightened to try anything new".

She shared: "I get so nervous with live performances that I'm too frightened to try anything new.

"It's actually getting worse. Or it's just not getting better, so I feel like it's getting worse, because it should've gotten better by now."

The record-breaking star revealed she was petrified of letting her fans down.

Adele added: "With my stage fright, I just don't want to let people down. I get so nervous onstage that I don't have the guts to improvise or anything like that."
