Steve Hansen wants greater depth in his squad while also looking at ideas for the 2015 World Cup.
More than anyone, he knows the All Black psyche and has a strong grasp on most of the potential pitfalls in the run-up to the next tournament.
After eight years riding shotgun for Graham Henry, Hansen has the marshal's badge pinned firmly to his chest as he nears the end of his second year in charge.
Hansen will have justified to himself, then the NZRU, why he needs 37 players on this tour and how he is going to get the best out of them as the tour heads to Paris, London and Dublin.
He will back himself and his staff to make inroads with the group and keep them well occupied. A handful will get an early leave pass once the England test is done but more than 30 will make the final week foray to Ireland. Hansen's logic will be that the new players, those coming back from injury and others on the cusp of All Black retention, will be as focused as those who suit up for the last hit-out in Dublin.
