Everyone who takes to Eden Park tonight is embarking on a 15-month exam they hope will leave them with a tick of approval for the next World Cup in England.
A large chunk of the All Black squad is contracted until the end of 2016 but there will be some wondering if they might enjoy a year or two in Europe or Japan, like Kaino, before returning for another tilt at making the 2019 tournament.

About 15 present and former All Blacks have signed through to the end of this year, another 15 until the end of the 2015 World Cup season, and a few others such as Read, Sam Whitelock and Ben Smith beyond that.
They are all now in the race to make the 31 who will search for successive global titles next season.
When all that's done, they will all need a breather and a review of their immediate future. In their down time a chat with Kaino might offer a useful interlude to the New Zealand rugby treadmill.
