Fans took to the internet to voice their displeasure.
Tweeter @jouljet said: "#BDO2012 announcement over 2 hours, and it's only a partial! Boring music lovers to the point of distraction!"
And on Facebook, Alexander Watts said: "Hey BIG DAY OUT OFFICIAL. I know you're a big deal, and I'mma let you finish, but do you understand what the internet is for?"
"I stayed up this whole time in nz and you ain't even announcing the headliners," said Miro Sudzim on Facebook.
Tanya Kerr said: "dear @bdo_official ,stop making us refresh every 10 seconds and just release the rest of the bands. sincerely, new zealand."
Trenton Hoata seemed to hit the nail on the head when he said: "You'd win everyone over if you'd just release the line up all in one hit."
But Big Day Out fans seemed to be happier about the line-up.
"This @bdo_official line up is to die for, which I will proceed to do when I buy my tickets," said @BridieJune.
And Dominicpink said: "You had me at Soundgarden, @bdo_official. Now don't go doing anything silly, like scheduling them the same time as Kanye or Battles."
