"This is what we wanted for him, to be able to go away and start enjoying his rugby again and get some things like this. If he'd been with us, he wouldn't have been able to do that," Hansen said on Friday. "It's a really big opportunity for him to enjoy what's always a good occasion."
Hansen maintained that the test door wasn't closed for Savea in 2018.
He'd been instructed to enjoy his time with the Robbie Deans-coached Baabaas, rejuvenate over the off-season and come back bigger and better than ever.
He'll return in time for next year's Brisbane Tens tournament.
Hansen is likely to select an understrength team to face the Baabaas, resting overworked All Blacks for the subsequent three tests.
As such, he wanted his younger players to come out firing, quell the likes of Savea and Andy Ellis and prove their worth in the black jumper.
Five other Kiwis will also play in black and white hoops.
"Having been involved, I was coach when we played Australia [in 2011] and they came out humming with the younger guys because they wanted to get themselves in that test squad - hopefully [ours] are the same," Hansen said.
