The Chiefs utility has been named at centre for his side's encounter with the Blues on Friday, continuing a season that has seen him shuffle along the champs' backline.
After a consistent run at wing, Nanai-Williams last week played fullback and has now been plugged into midfield to fill the hole left by the injured Charlie Ngatai.
The 24-year-old could be forgiven for double-checking the number on his jersey before he runs out every week but, with no favoured position, Nanai-Williams relishes the varying challenges found all over the field.
"I'm just happy wherever I can play a part for the team - and I'm not just saying that," he said. "I enjoy the challenge when I don't know where I'm going to play till two days out from the game.
"I have to adjust from where I usually play on the wing, to playing centre, to playing fullback. But I enjoy every minute and where I play doesn't bother me."
Part of that enjoyment stems from a freedom bestowed by the Chiefs coaches. While Nanai-Williams will seemingly have more involvement at fullback or centre, his special instructions allow him to exert influence when playing on the wing.
"Our coaches give me a licence to just roam around. I'm another fullback, another centre, even though I'm playing wing. I can just roam around and play first receiver, or run back-door plays."
Nanai-Williams' versatility has seen him start 10 of the Chiefs' 11 games this season - no other back has been selected in more than eight matches - and makes for a welcome return to consistent rugby.
The Counties-Manukau man missed the second half of last year with a torn adductor muscle, and he credits a highly-structured preseason with his durability during the current campaign.
"Most of these boys were getting grilled in preseason but I was coming back from an adductor and I just gradually built myself into getting back. I was lucky enough to make it in time for the first game, and I've just been looking after my body really well."
He will hope that continues this weekend, with the Chiefs aiming to enter their second bye on a winning note. More crocked teammates should return following the break but Nanai-Williams will undoubtedly find a space for himself somewhere in the side.
