Ai'i, who played for club side College Rifles this year and turns 34 in nine days, said the new boys gave him a dose of enthusiasm.
"They keep me young at heart as well,'' Ai'i said. ``It's good to see these young blokes coming through and it's an opportunity for me to help them with my experience and enjoy their company on the field.''
Those young blokes are also happy to remind Ai'i he is one of the elder statesmen in this year's ITM Cup.
"A lot of the young boys give me a bit of crap saying `old man' or `I was just a thought in my parents' mind [when you first played]','' Ai'i laughed.
"But for me it's quite humbling because I've seen a lot of great players, younger than me, retire at an early age and for me to keep playing, it's a good thing.''
Ai'i played from the bench for Auckland in last weekend' 51-15 rout against Taranaki in New Plymouth, which marked his first appearance in the blue and white hoops since 2005.
The 1.70m utility wasn't required by Auckland last year and spent time with Northland but his veteran experience is gold this season in an exciting Auckland squad.
Wayne Pivac's side have won their first five games and only a diehard Waikato fan would bet against them making it six from six today.
Considering halfback Piri Weepu blew out 30 candles last Saturday, Ai'i and the former All Black will make up the oldest inside back pairing in the competition this weekend.
"He's excited actually, I think he feels a lot more mature now,'' Ai'i said of Weepu. "Being 30 there's only three of us in the 30-club but we just mix it up with these young boys.''
Injured No 9 Junior Poluleuligaga is the other member of the older brigade at 32.
Ai'i said he still had a couple of good years left in him and wouldn't rule out another stint offshore if the offer was right. He spent most of this year setting up a gym with some friends in South Auckland where he is based, while his prowess as a sevens player has taken him to Sri Lanka and England.
Kick-off in Hamilton is at 2.35pm.
