Hundreds of screaming teenagers packed St James Theatre last night to worship idols One Direction during their only Wellington concert.
Earlier, security watched as the girls - many wearing homemade costumes emblazoned with the names of their beloved boy-band members - jumped around excitedly in a line that snaked down Courtenay Place.
Inside, a group of fans were wrapped in Irish flags, the home country of Niall Horan, while others had "1D" scribbled on their faces.
It was a day when One Direction madness erupted in the capital.
Hordes of teens descended on Wellington Airport in the morning to greet the biggest boy band on the planet.
Teenage girls, some near hysterics, took over Gate 11, as their idols landed at noon. Some fans perched precariously on window ledges for a glimpse of Horan, Zayn Malik, Louis Tomlinson, Liam Payne and Harry Styles.
They were thrilled to catch a glimpse of the lads, who sauntered down the steps of the Air New Zealand jet.
One Direction offered a couple of brief waves before they were whisked off the tarmac in a black van with tinted windows.
Fan Leilani Manu, 13, said she had missed out on tickets to last night's St James Theatre concert, but catching a glimpse of them in the flesh more than made up for it. "I just love them."
Fans had rushed to the gate of every arriving plane all morning.
"They're really, really good," Kendall Northcott, 12, of Wellington, said. "They're my favourite boy band."
After the group's rock star airport exit, about 300 teens besieged the InterContinental hotel. Teasing waves from a window prompted more mass hysteria.
Three girls made a break for it, running for the underground car park before they were corralled by security.
Mykaela Riley, 15, of Wellington, was among those in the crowd.
She had attended the Auckland concert on Saturday and said it was the best experience of her whole life. "They are just amazing and so beautiful."
The oldest fan there was Harriet Shearer, 82.
She was hanging out outside the hotel with her great nieces, wearing a white One Direction T-shirt and shrugging away offers of a cardie.
"I think they make a lot of people happy," she said. "I'm not sure what will happen to them when they get older, but right now they are doing a lot of good."
One Direction's only album is Up All Night.
