Packer, who made his debut with the Warriors in 2008 and racked 110 caps before his career went off-track, was delighted to reunite with Cleary and secure his NRL future but admits he feels a debt of gratitude to the Dragons, who gave him a chance to resurrect his career after a prison stint for an ugly late night assault.
"It's good to secure a future for my family and I, but that's in 2018," Packer explained. "My sole focus is on this year with the Dragons.
"Under the circumstances that I came to the club, having that ability to rebuild my career as a rugby league player but also my life, I have the utmost respect for everybody involved at the Dragons," he added.
"There are too many people to thank for the almost three years I've been here."
The Dragons were rank outsiders at the beginning of the season but made a stunning start to the year before losing star rep players Gareth Widdop and Josh Dugan to injury in the past three weeks, where they have had narrow losses to the Roosters, Storm and Sharks.
Packer is hoping the trip across the Tasman yields a vital two competition points.
"We've had a couple of tough losses in the past few weeks so I'm hoping we get back on track in New Zealand."
