Chris Goldsbury said: "Yep whoops @MasterChefNZ gave it away early.. fail!"
At the end of the show Masterchef also posted a tweet about the gaffe.
"Sorry for the spoiler guys, we're going to make sure this doesn't happen again. Thanks for watching!"
Glading retweeted a number of posts about her eliminiation at the end of the show including one from broadcaster Hilary Barry who outed herself on Twitter as a fan of the young aspiring chef.
She is yet to comment on her elimination or the botched announcement.
Glading was the youngest contestant on the reality cooking show.
She is a commerce student and according to her Masterchef bio her ultimate food dream is to "own a fine dining, hatted restaurant somewhere in Sydney or Melbourne".
Her motto was to "stay calm, breathe, stop and think. Do what I love, trust my instincts, have confidence in all that I do and enjoy myself".
