Sir Elton John halts Auckland concert after 'walking pneumonia' diagnosis

A visibly upset Sir Elton John has been forced to halt his Auckland concert on Sunday night after his voice gave out.

"I've just completely lost my voice - I'm so sorry," he said, looking very emotional before he was helped off stage.

Earlier, the superstar singer and pianist told the crowd he had been diagnosed with "walking pneumonia".

"My voice is shot," he told fans, adding he didn't want to miss the first of his three Auckland shows.

Walking pneumonia is an infection caused by bacteria that mostly affects people's respiratory tracts. It's less severe than other forms of pneumonia, but can still leave people feeling sick.

Sir Elton was given medical attention on stage, while paramedics were seen waiting with a stretcher in case he collapsed.

"I don't know how much longer I can sing. I just don't have anything left. I will try but I just can't promise anything," he told the crowd.

But despite his efforts to battle through his set, he was forced to cut his show short.

Fans heartbroken

Sir Elton's premature departure left multiple fans in tears.

"He tried so so hard... but his voice was completely f**ked," one told Newshub.

"Just feel so sorry for him."

Future of other shows uncertain

Sir Elton is performing six shows here on his Farewell Yellow Brick Road tour, which covers five continents across 300 shows.

At this stage, it's unclear whether his next Auckland shows - on Tuesday and Thursday - will go ahead.

He first visited Aotearoa in 1971, playing Auckland's Western Springs Stadium. Since then, he's brought at least 12 more tours to Kiwi audiences.
