The door remains open for Cory Jane to play his way into the final 31 and, with Waisake Naholo having been medically assessed since he returned from Fiji and on track to be fit to play by the third game of the World Cup, the blurriest bit is still the back three.
It is blurry on two fronts: the first is the potential number of spots that may be available.
The long held assumption has been there will be room for four outside backs, but it is not inconceivable according to head coach Steve Hansen that the All Blacks will travel to England with four rather than five props - as long as one is genuinely capable of covering both sides of the scrum.
Nor have they ruled out - not publicly anyway - taking just two specialist halfbacks. The risks in both scenarios appear to outweigh the potential rewards and, in all likelihood, the All Blacks will take five props and three halfbacks - leaving room for just four outside backs.
And then the question is which four? Julian Savea and Ben Smith have long been certainties and, despite the former's fitness issues post Super rugby, confirmed that fact in the past two tests.
It becomes an awfully difficult decision after that. Nehe Milner Skudder, whose injury is not serious, showed again that his fast feet, awareness and elusive running can split the meanest defence.
Charles Piutau can feel he did plenty to advance his cause with the opportunities he had and Israel Dagg, who had bright spots and quiet patches, does have years of consistent performance to sway the decision.
''There have probably been a couple of guys who have made us think more about the type of combinations we want to take,'' says Hansen.
''People like Waisake [Naholo] and Nehe [Milner Skudder] we didn't know anything about.
''So they have really challenged our thought process and guys like CJ [Cory Jane] haven't played. There is still room for one or two names to swap around but by and large, it's starting to become reasonably solid.''
Confirmation that Charlie Faumuina will be fit to play for Auckland in the ITM Cup and is also in supreme condition after his neck injury, means that he is a strong contender to make it into the final 31.
And although there was limited opportunity to assess the merits of Jerome Kaino as a stand in lock at Eden Park, the All Blacks appear to have firmed on their view that they may get away with taking only three specialist second rowers to England.
A solid performance by Victor Vito helped in that regard - strengthening the case to have six loose forwards in the mix - but Hansen also confirmed the selection mantra once the All Blacks get to the World Cup, will be consistency.
''I think we saw a different type of game last night - more direct,'' he said.
''In the other games we were looking to go wide all the time but I think we subtly got that mix right.''
