"There will be some people who will be disappointed, and you can understand that because it was a very tough team to pick," Hansen said. "But [the Samoa test] may even mean we have to bring in some extra players.
"There's some guys who we deliberately left out of the 41 who were on the fringe, because they can play for the Baabaas and they can play for the Maori side."
Even if the season ends this weekend for the Hurricanes' or Highlanders' All Blacks, their availability doesn't necessarily guarantee their involvement against Samoa. Hansen was wary of the high workloads some players had endured in guiding their franchises to the final four, with the likes of Ben Smith (1092 minutes), Julian Savea (1087) and Conrad Smith (1080) potentially in need of a week off.
"We'll go through them as individuals and see how many minutes they've had this season," Hansen said. "Some have been really high. We're taking 29 to Samoa, so there will be some who can come over but hopefully we don't have to use the high-end guys. We'll just give them a week."
The number of players carrying injury creates another complication in all the sums. Nepo Laulala and Andy Ellis have already been named as injury replacements for Charles Faumuina and Tawera Kerr-Barlow, respectively, while Israel Dagg and Charles Piutau are also short of fitness.
"You're concerned that they're not back on the playing field, but they're not career-ending injuries," Hansen said. "I'm confident that our medical crew will get them right."
