On Sunday, All Blacks coach Steve Hansen will name his 30-strong squad to meet Ireland in three tests next month and Cruden and Cane's names are pretty safe bets to be on the teamsheet.
The second training camp wrapped up in Wellington today and Cane said it was great to be able to get to know some of the players in the squad and, of course, pick the brain of the captain.
"It's unbelievable, I've grown up watching Richie and definitely idolised his play and how he is, so to be running alongside him at training and having a chat to him is absolutely amazing and something I really enjoyed."
Cane said he would likely watch the squad naming on Sunday but wanted to put in a good performance for the Chiefs when they meet the Blues in Albany on Saturday night and wasn't expecting to take McCaw's spot in the national side yet.
"All I'll be doing is pushing to get named in the squad first of all and from there, you're pushing to get in the 22, so I'm not getting too far ahead of myself."
Cruden, who debuted for the All Blacks against Wales in 2010 as a 21-year-old, said he was excited to be back in the All Blacks environment, even if it meant riding the pine behind test rugby's greatest points-scorer.
"I think it's pretty cool. I still think Dan's the best 10 in the world and if I'm able to learn from him then it's exactly what I'm going to do and he's a great guy. He's always willing to help out the new guys and guys in his position, so I'm just going to soak it all in, all of the info he gives me."
As for how much time he would see on the paddock against the Irish, Cruden didn't have any expectations.
"I'm not too sure. Always hoping to get on the field, but I'll just have to see how it goes and push my claim at training and do what I can to hopefully get a bit of game time during that series."
