“I got competitive… really competitive.”

Also in the final three was True Bliss star and radio host Joe Cotton, who was unmasked as Medusa, and singer/songwriter Troy Kingi, who was revealed as Sheep.
The show’s guessing panel had mixed ideas about Tuatara’s identity, with Rhys Darby thinking it could be fellow comedians Jason Hoyt or Jemaine Clement, while James Roque was convinced the singer was X Factor NZ alumni Benny Tipene.
Both Sharyn Casey and Ladi6 correctly guessed Kerrison as the man behind the scaly mask.
Kerrison said that at first he felt “weirded out” by the premise of the show – dressing up in an elaborate costume to compete in a national televised singing competition. 
“But once I checked it out and saw that Gladys Knight, Chaka Khan, John Legend, Dion Warwick, Patti LaBelle and Joss Stone – among other legends – had done it, I kinda realised I may have been taking myself too seriously and thought, bugger it, let’s have some fun!” he said in a statement.
