The Australian choreographer, who became notorious for his cutting critiques and an infamous on-air fight with DOI coach Karen Barber, was replaced by Louie Spence last series.
Speaking to Digital Spy after officially announcing his comeback, Gardiner stated that he will give Dancing on Ice "the spice it needs".
"It feels right [to return]," he said. "For the whole year that I wasn't there... there was a piece missing.
"I think I can only help [the show]... I bring the controversy, I guess. I keep it very interesting and I keep it real.
"I'm not going to back down because it gets a bit too hot. I'm there to do my job in my professional capacity and I will always do that."

Asked if he regrets anything said on Dancing on Ice in the past, Gardiner replied: "There are some things that I wish didn't play out in front of 10 million but, hey, it's live TV and these things happen.
"We're real people in kind of unreal situations. Things can go amiss sometimes. But I don't regret anything. You only regret the things you don't do in life and I do most of them."
The panellist also teased that next year's Dancing on Ice boasts the "best lineup of celebrities" yet who will make "for a very good series".
Naming The Dark Knight Rises star Tom Hardy as his dream Dancing on Ice contestant, Gardiner gave his stamp of approval to rumoured participants Pamela Anderson, TOWIE's Lauren Goodger and X Factor winner Shayne Ward.
"What's great about them is I know who they are," he jested. "Any of those would be great.
"All of them [are] eye candy for a start. They're gonna look great in lycra and sequins, so that helps."
Dancing on Ice launches on ITV1 in January.
