Brace yourself, Wellington. The city is due to be rocked by the iconic Guns N' Roses tonight as the cold February rain shows no sign of stopping.

The band's longtime production manager Dale Skjerseth said the only problem with Thursday night's show would be the weather.

"I've been here many times, so I know it. We can go with it," he said.

Guns N' Roses prepare for a rainy concert in the capital at Westpac Stadium.

He advised any punters who were planning to get in the thick of it on Westpac Stadium's field to bring a jacket. It wasn't going to be a cold night, he said, the minimum temperature was 13 degrees Celsius.

Westpac Stadium chief executive Shane Harmon doused any fears that the concert might be cancelled.

"It's full steam ahead, gates open at five o'clock.

It's going to be a wet one, Wellington. Guns N' Roses get ready for their Westpac Stadium show that is part of the band's Not in this Lifetime tour.

"We are hoping by showtime the rain will clear. It'll obviously be a bit damp but we have covering over most of the stadium and there's plenty of room in the concourse to stay dry until the bands come on stage."

The Not in this Lifetime tour is the band's seventh tour since their formation in 1985.

Their production manger, who has been with Guns N' Roses for 20 years, said time hadn't taken any energy from the band.

"It don't hinder nothing. It makes it better. As time goes on, you realise what you did then and now how much better you can make it," Skjerseth said.

Guns N' Roses would take to the stage promptly at 8pm, Skjerseth said. According to him, the band had outgrown their old habits of notoriously late arrivals or even missing entire concerts.

Their set was planned to last almost three hours, kicking off at 8pm.

The set list included all the classics, as well as a few newer songs, Skjerseth said.

Australian hard rock group Wolfmother would be on stage from 6.45pm.

Harmon​ predicted near sellout crowds for the concert, despite the weather. 

This was the biggest show to be hosted at Westpac Stadium since AC/DC​ visited in 2010, Harmon said, and he expected about 40,000 people.
