Elton John intends to play his remaining shows in New Zealand this week, his tour promoters have said, a day after illness caused the singer to lose his voice and cut short a performance.
Video clips posted online at Sunday night's performance showed John breaking down in tears as he told the crowd he could not go on any longer.
The 72-year-old singer said he had walking pneumonia and was assisted off stage.
Tour promoters Chugg Entertainment said John was resting and doctors are confident he will recover.
"Elton John was disappointed and deeply upset at having to end his Auckland concert early last night," the promoters' statement said. "At this stage, all remaining shows will go ahead as planned."
The concert was part of John's Farewell Yellow Brick Road tour.
He thanked the concert attendees via an Instagram post and apologised for ending the show early.
"I want to thank everyone who attended tonight's gig in Auckland. I was diagnosed with walking pneumonia earlier today, but I was determined to give you the best show humanly possible," John wrote. "I played and sang my heart out, until my voice could sing no more. I'm disappointed, deeply upset and sorry. I gave it all I had."
John had just returned to New Zealand after performing at the Academy Awards in Los Angeles. He won an Oscar for best original song for his theme song for the movie "Rocketman."
According to the Mayo Clinic, walking pneumonia is an informal term for a milder form of pneumonia that isn't severe enough to require hospitalisation or bed rest.
