A sign of the times in Auckland as tens of thousands of eager fans flock to see Harry Styles.

The star's performing at Mount Smart Stadium tonight, with queues starting to form outside the stadium from 4:00am this morning.

One concert-goer, Emily Calbert says she was in line from 6:30am.

"They said that the doors would open around 8, and that was our original plan, but then we did actually speak to a security lady yesterday and she said that there would be people lining up most likely a little bit before that."
