The band, comprising Tomlinson, 23, Niall Horan, 22, Liam Payne, 22, and Harry Styles, 21, were formed by Simon Cowell on X Factor in 2010.
A fifth member, Zayn Malik, 22, quit due to stress in March this year.
He has since signed a new recording deal as a solo artist.
"I am leaving because I want to be a normal 22-year-old who is able to relax and have some private time out of the spotlight," Malik said at the time.
Horan admitted the last gig of the tour would be difficult and taking a break from their busy schedule would feel slightly odd for the foursome.

The Sunday Times newspaper's Rich List 2015 revealed the band members were worth NZD $56 million each.
