All Black and Chiefs playmaker Aaron Cruden believes that he has grown as a player under assistant coach Wayne Smith.
The back up first-five eight for the All Blacks is currently in a national camp in Wellington with All Black coaches Steve Hansen, Aussie McLean and Ian Foster.
Cruden says that former All Blacks assistant Smith has made a big difference to the way he has developed this season.
"It's been huge," Cruden told Newztalk ZB.
"Smitty's a great guy and a former 10 as well, so for me playing that position it's been great.
"He's given me a lot of wisdom."
Players at the training camp will return to their Super Rugby franchises on Tuesday evening in order to prepare for this weekend's Super Rugby matches.
