More than 100,000 Kiwi fans will see Adele over the three nights she performs in Auckland - the star did something no-one else has done by selling out the shows in a record two hours.

Her first concert on Thursday night received rave reviews. During the show, Adele paid tribute to the London terror attack victims.

And those heading to tonight's concert have taken to social media to express there excitement, with one fan saying she'd been too excited to sleep last night.

Ahhhh! @Adele weekend is officially starting! Bye Upper Hutt see you Monday! Bring on Auckland

Adele's tour has put pressure on Auckland's infrastructure as fans from all over the country travelled to the city of sails for the gig.

Many hostels, motels and hotels in the central city are booked out for the weekend and
traffic on Auckland's southern motorway is heavy at Penrose.

Fans were earlier caught in a traffic snarl-up south of Auckland.

A seven-car crash on State Highway 1 at the Gordonton Rd off-ramp at Taupiri had backed up traffic to well south of the rural Waikato township.

Herald writer David Leggat was caught up in the chaos. It took him an hour to drive to Huntly from Hamilton - twice as long as usual.

"It has been bumper to bumper all the way, it's hopeless," he said. "I am trying to get back to Auckland but it will take hours, once I hit the Adele traffic too.

"It is going to be a long afternoon."

Traffic chaos was even reported as far away as in Queenstown.

However, good news for Adele fans is the weather should be better than first expected.

"It will be cloudy and there could be an isolated shower or two later in the evening, so best pack something waterproof," MetService forecaster Angus Hines said.

"But it will be a pleasant enough evening, with the temperature about 20 degrees.

"It is expected to be a lot wetter for the Adele show tomorrow night."

Public transport arrangements are slightly different for this weekend's shows than they were for Thursday, with special events buses going from opposite Queens Wharf on Quay St.

If you're travelling from the North Shore, there won't be event buses, you can travel free into the city on Northern Express services from 3.30pm by showing your concert ticket. When you reach the city follow the signage to the event buses or the trains.

There will be extra services on the Northern Express before and after the concerts.

There will again be additional trains before and after the concerts on the Southern and Onehunga Lines to and from Penrose Station. From there it's a 10 to 15 minute walk to the stadium.

There will also be special late ferries to Devonport, extra Northern Express buses and late trains.

"We've managed to increase capacity on buses and trains for both Saturday and Sunday nights," Brendon Main, group manager of AT Metro Operations, said.

If you're heading to the concerts, the roads will be busy and there will be some temporary parking restrictions and road closures in the area of the stadium, he added.
