Angry fans were stuck outside tonight's Guns N' Roses concert as the band started playing Welcome to the Jungle.
A source at the concert said staff told people waiting outside Gate B that they had run out of wrist bands and needed to source some more.
People stuck at the turnstiles became angry at security staff as they heard the band come onto the stage.
They were particularly frustrated when they heard the band charge into their classic Welcome to the Jungle.
After about 15-20 minutes of waiting staff gave up and let people into the ground without wrist bands.
Auckland Stadiums director Paul Nisbet said the issue occurred about 8.30pm when the last 20 - 30 people to the venue were held up.
The delay was "minimal".
"There were 50,000 people in the venue at the time and at the end of the day, the gates opened at 5.30pm. This incident happened at 8.30pm.
"It is unfortunate 20 - 30 people were affected by it, it's unfortunate and we're sorry that they missed that particular song. But I think it was about three or four songs into the concert ... and at the end of the day it's been a great night, it's been a sensational night."
Nisbet understood the decision to let the crowd in without wrist bands was made without any great delay.
The band's first show in Wellington on Thursday also got off to a shaky start.
Thousands of fans faced a 90-minute delay in the pouring rain outside Westpac Stadium after the venue's turnstiles stopped working.
Fans faced further delays once inside the stadium, as they needed to exchange their tickets for a wristband.
Guns N' Roses to rock Auckland tonight
The Slash lookalikes and ripped jeans were out in force at Western Springs stadium this evening ahead of Guns N' Roses' much anticipated Auckland show.
It is the first time the band's founding members Axl Rose, Slash and Duff McKagan have toured New Zealand since 1993 and the fans were more than ready to rock.
With the group now in their 50s, the Gunners pull a slightly older crowd than in their heyday and the thousands outside the stadium were a pretty well behaved bunch.
But despite a liquor ban and big police presence, many used the surrounding streets and park to sink a few beers or bourbon and Cokes.
Unlike in Wellington on Thursday where the show was hampered by poor weather and long delays, Auckland put on a pearler of a day with full sunshine and a gentle breeze adding to the festival atmosphere.
Josh Marston, who came up from Hamilton, was animated ahead of the gig.
"What's the appeal? Realism, rockstars, old-school, attitude. Everyone's on the radio listening to Justin Bieber, listening to Katy Perry -- don't get me wrong, talented people -- but the attitude, we've lost our balls as a society. These guys are bringing it back."
Lee Dixon has been a fan for 24 years and will be seeing the band for the second time tonight.
"We're re-living our youth," he said. "They're just a fantastic band."
Lormar Bell was one of countless Guns N' Roses faithful to come wearing a top hat like the one made famous by the group's enigmatic guitarist, Slash. She also had a perfect t-shirt for the occasion, with the logo "sun's out, guns out".
"It's my second [time seeing them. Their concert was my very first concert when I was younger ... about 18, 19."
"They're just rocking it on, we love it."
James Rainsford, 16, was one of a fair few youngsters at the gig, and said Guns N' Roses music was timeless, no matter what generation you're from.
"It's just good music, good, classic rock songs", he said.
Not In This Lifetime is the latest tour for the band, which formed in 1985.
The group will be joined by Australian outfit Wolfmother as the supporting act.
As Auckland is due to be rocked by the legendary band tonight fans will rejoice, the sun is shining.
With day one of the NRL Nines drawing to an end and the Guns N' Roses gearing up to perform at Western Springs Stadium, it is traffic mayhem on Auckland roads.
NZTA is urging fans and commuters alike to avoid delays near Eden Park and Western Springs by taking an alternative route.
"Expect long delays from CBD for traffic on Nth Wstn Mwy heading off at St Lukes off-ramp," NZTA said on Twitter.
With crowds of rugby league and rock fans expected to move from the Nines to the concert, Auckland Council and Nines promoter Downer have mapped out the best route.
The 25-minute walk starts at Eden Park before heading over Bond St Bridge, through Arch Hill Scenic Reserve to Western Springs Stadium.
Rockers from further afar fear not - free travel on event buses and trains is included with your concert ticket.

Queues of thousands of fans faced a 90-minute delay in the pouring rain outside Westpac Stadium after the venue's turnstiles stopped working.

A Herald reviewer said Guns N' Roses appeared on stage an hour past their scheduled 8pm start time, with the delay "unexplained".
