The 21-year-old's growing impact has prospered and when he was called up late to replace his damaged captain, Cane was a standout in Saturday's 41-33 victory against the Wallabies.
When a 36-strong touring squad was announced yesterday for the tour to Japan, France, England and Ireland, Frank Halai, Dominic Bird, Luke Whitelock and Joe Moody were the new picks.
Uncapped halfback TJ Perenara passed a medical test on the stress fracture in his foot to make the tour and Luke Romano was also passed fit after his groin muscle injury.
There was one shock with 20-year-old Wellington looseforward Ardie Savea named in a new "apprentice" scheme as a player the All Blacks would take on tour.
It would have been easy for the All Blacks to have left him at home with instructions to bulk up some more and then, like the cluster of promising young hookers they are monitoring, show his credentials in next year's Super 15.
Settling on Savea for this tour suggests the All Black selectors think he is easily the next best prospect behind Cane, he will be a test player soon and that after 120 tests, McCaw's endurance may be waning.
There is quality throughout the group who rollicked through their latest challenge with their third win this season against the Wallabies in Dunedin. That was the 10th straight win for the All Blacks, who will regroup on Friday in Auckland for a two-day camp, after visits to smaller towns.
Their form has been enterprising, physical and athletic in clumps of form this season and they have decided to take 27 players to Japan and send nine others to start their tour in France. Those choices will be finalised this week because a number will have to survive the ITM Cup final on Saturday before the squad leaves for Japan on Monday.
In such a large squad Ben Franks, Jeremy Thrush and Whitelock seem marginal picks but plenty of research, versatility, injury and hunches will have gone into their selection.
All of the touring group except Bird, who was injured, and the "apprentice" Savea have been training this season with the All Blacks. The side starts the tour against Japan on November 2 in Tokyo and finishes with a Monday morning (NZ time) test against Ireland on November 25.
