Zach Tuohy believes his move to Geelong from Carlton at the end of the 2016 season was one that's rejuvenated his career.

The 27-year-old has been an important member of Chris Scott's side this season, averaging 24 disposals and five score involvements across the Cats' 5-0 start to the year.

Tuohy made the switch to Geelong after 120 games across seven years at Carlton, and only managed to play in 48 wins for the Blues in a period without much success.

The Irishman was on the lookout for a winning culture, and he believes the current situation he's in lends him to being the most happiest he's been in his career.

“The change has been incredibly refreshing for me. There’s no getting away from that and I probably needed it and obviously when you’re winning games of footy you enjoy it more. That goes without saying,” Tuohy told RSN 927.

“I really needed the change towards the back end of last year and as much as I adored my time at Carlton, and I really did, I think the path they’re going down and the point I’m at in my career didn’t really match up.

"But I’m probably the happiest I’ve ever been in terms of on-field, off-field at the minute and that’s exactly what I was hoping to achieve when I came here.”

The former Blue admitted he hasn't fully adjusted to Geelong's game-plan just yet, and says while the Cats haven't played their best footy to start the year, it's not a bad position to be in with their 5-0 record.

“It’s still a work in progress and as much as I’ve settled in I’m still adjusting to just how they’re playing,” Tuohy said.

“We’re 5-0 off not playing our best footy so that’s a good position to be in.”
