fans are turning on judge Jesse J calling her an "idiot", saying she "acted jealous and bitter and twisted" and labelling her decisions a "fail" after she dropped two Kiwi acts from the show.
Kiwi trio the Koi Boys were axed from the show and Wellington singer Aaliyah Warren was dropped from Jesse J's team, but saved by the Madden brothers.
Jesse dropped 17-year-old Warren because she was too young.
"I want to protect you and build on your personality and who you are. I think you could go a long way but I don't think that is on TV. I don't think you are ready yet and I hope you understand," she told Warren.
Joel and Benji stepped in with a save, saying they agreed but Warren had "a lot of potential".
Fans were full of praise for the Maddens for saving the singer, and far less kind to Jessie J.
But it was the judge's decision to drop series favourites the Koi Boys, that really set off fans.
Despite being an audience favourite, the Koi Boys' act was "very boy-bandy, and very 'done'", she said - a call viewers have not taken lightly.
The Koi Boys took to Facebook after the show, saying, "Sad outcome but we will continue to do what we do best".
They wished their fellow teammates luck, and said they were "humbled to share the stage with these very talented people". However, they also posted the results of the viewers' preferences, saying: "If only it was up to the people to make the choice".
