The prospect of coaching such a young squad is obviously an exciting prospect for Kirwan. Kirwan said he's leaning on a number of old hands including Michael Jones, Craig Innes, Joeli Vidiri and Gus Collins to educate his players about what it means to be a Blues player.
The only current All Blacks are forwards Ali Williams, Keven Mealamu and Charlie Faumuina along with last year's recuit Piri Weepu.
Fellow All Blacks Nonu and Tony Woodcock departed in the off season for the Highlanders.
Amongst the new players in the squad are Counties Manukau first five-eighth Baden Kerr, Canterbury loose forward Brendon O'Connor, Bay of Plenty lock Culum Retallick and Waikato midfield back Jackson Willison.
Missing however is Daniel Braid.
The Blues flanker, 31, who played six tests over eight years, had hoped to pick something up at the last minute after being told by Sir John Kirwan that his services were no longer required, but it is understood that the best offer he received was a place in the Auckland franchise's wider training group.
It is understood that he is considering an offer from an English club.
