The All Blacks jigsaw is crammed with backs but missing some forwards pieces.
Short-term the task is to drive a group through next month's test series against France while the longer vision is to fashion a squad for the 2019 World Cup.
Injuries have trimmed the forward choices and while Wyatt Crockett and Jerome Kaino would offer strong cover, picking Crockett who has retired from test rugby and Kaino who is heading to France, won't help the side's development.
Medical reports will impact on the selection of Liam Squire and Nepo Laulala and there may be some weekend attrition before coach Steve Hansen unveils a likely squad of 18 forwards and 15 backs. That mix is fluid and others may be picked as cover or to train with the squad before the Auckland, Wellington and Dunedin tests.
Some good players will miss the cut because of the quality of their rivals and Israel Dagg, Julian Savea, David Havili, Ben Lam and Solomon Alaimalo are at risk in the group vying for the fullback-wing choices.
