Returning to the All Blacks fold in time for the mid-year British and Irish Lions tour of New Zealand would be the next goal.
"It's obviously in the back of my mind, in the forefront it's about running and doing that sort of stuff," the four-cap Harris said.
"My feet are starting to itch."
Having been forced out of the game for so long, Harris said he'd resorted to fishing, diving, studying and rugby coaching to pass free time.
He felt his role as mentor for a precocious Chiefs squad could help pave the way for the franchise's third Super Rugby title in 2017.
That would be especially important given the long-term injuries sustained by Brad Weber and Mitchell Graham in last week's Brisbane Tens triumph.
"Being a good team member for the boys who are new or coming up through the ranks, lending them a helping hand," Harris said.
"I knew what it was like to come into an environment, so just helping and guiding."
