The 60-year-old, who was born in Australia, was in temporary charge of the club during their first season in Super League and he will assist new coach Laurent Frayssinous.
“I’ve been involved at the start of the Catalans’ history and I’m excited to come back to the club,” Waite said.
“I’m very happy to work with Laurent. I want to focus on the game and the individual now. I’m back on the field with the players and I’m looking forward to this experience.
“I believe Laurent has the potential to become a great head coach. He has worked really hard for that and I want to help him and the club to achieve the goals and to become more successful.”
Elsewhere, Hull KR have made young Huddersfield forward Adam Miller their seventh signing for 2013.
The 21 year-old will link up with his new club immediately after the two clubs agreed an undisclosed release fee and a three-year contract was agreed.
“Adam fits the profile that we’re looking for in that he’s young, he’s English and he’s very keen to learn and improve as a player,” Robins’ boss Craig Sandercock said.
“I watched him a few times last season and was very impressed with what I saw.
“He has a lot of potential and if he works hard and maintains the right attitude then he has a great chance of establishing himself as a Super League player.”
