Social media has become a popular way for music festivals to reveal line-ups lately, with Australia's Soundwave festival recently announcing its line-up over several days to gain more traction on Twitter.
There are always plenty of rumours flying around about Big Day Out line-ups, and next year's has been no different with everyone from Prince to Eminem suggested as headliners.
More likely suggestions include System of a Down, Arcade Fire, Bjork and PJ Harvey.
Two acts already seem certain to appear on the bill, with British rockers Kasabian confirming a second-to-last mainstage slot to an Australian magazine, while wacky rap group Odd Future also let it slip they were coming Down Under in the New Year.
The date for the New Zealand leg of the Big Day Out 2012 is believed to be Friday, January 20 at Mt Smart Stadium in Auckland.
* The full line-up will be available on Friday morning on nzherald.co.nz, followed by a live chat with New Zealand Big Day Out promoter Campbell Smith.
