The test in New Plymouth was the perfect opportunity to give Ben Smith a better feel for a role he will likely be asked to fill later this year.
The All Blacks have won the series; there's no such thing as an easy test, but no question, the game in New Plymouth won't be viewed in the same way as an encounter against the Springboks or Wallabies or England at Twickenham.
Selecting Ben Smith would have minimised the risks that await later this year when either he or someone else will have to wear No13 in Paris, London and Dublin.
Conversely, with Rene Ranger almost certainly heading to Montpellier in October, is it valid to give him a start this week? His form deserves it - but this, as Hansen says, is a year where he feels he has to take risks. Selecting Ranger on the wing might seem curious - it has no longevity and while he's played well in cameo appearances, Savea was equally impressive in Christchurch and his confidence would benefit from another run this Saturday.
But Ranger will be around for the Rugby Championship and he can play a key role in helping the All Blacks win that.
Looking at the bench, the inference is that should the All Blacks get the game safely under control, Conrad Smith will be taken off, Ben Smith put into the midfield and Charles Piutau given his debut. If that happens, those final 20 minutes or so will be about preparing for the longer-term future.
