Seems like they'll likely have to use Fin Christie at halfback, so I reckon beyond that there will be a maximum of two changes in the backs.
Vaguely possible that they'll switch Beaudy for DMac, but given they've hitched the wagon to BB for all the preceding tests, I don't see this happening. If Eden Park is a disaster, that change will get made.
Jordie is locked in.
Proctor has been a bit of an experiment - not entirely successful, but worth continuing with in the long run. But, maybe not for this game. I could see Rieko possibly moving to the 13 jersey.
I think they'll be watching Caleb Clarke's form anxiously in NPC this weekend. Now that he's got his motorcycle madness out the way, hopefully he can be focussed and recapture last year's form. If he goes well, I reckon he'll be in. If Rieko doesn't move to centre, there's a possibility he'd move to right wing for Sevu - but, probably not. Narawa also a possibility to replace Sevu.
Jordan locked in at fullback - would be quite a surprise for me if they shifted him to wing to accommodate DMac or Love.
