The Irish lasses will be sure to bust out a few faves like C'est La Vie and Rollercoaster.
English girl group Atomic Kitten will join them, performing for the first time in New Zealand.
They topped the NZ Charts in 2001 with their song Whole Again and were behind the popular covers of Eternal Flame and The Tide is High.
Oh the memories!
And last but not least to join this astounding lineup is S Club 3.
The three remaining members of the S Club crew are Jo O'Meara, Tina Barrett and Bradley McIntosh.
They will be Bringing It All Back with smash hits like Don't Stop Movin' and Two In A Million.
It's all going down Saturday February 4 at Auckland's ASB Theatre.
Tickets go on sale this Thursday, September 1.
Get excited.
