Williams injured his knee against Ireland in Christchurch, but this weekend has been called into the All Blacks camp, playing a limited role in training, while spending time with other locks in the group.
There is hope that Williams will get some game time for Auckland in the ITM Cup, but if his fitness is proved, it is likely that the 75-test lock will travel and may suit up for the All Blacks first tour match against Scotland in Edinburgh.
Hansen has already indicated that a fit Williams should feature.
At this stage the All Blacks are carrying just three fit locks, with Sam Whitelock, Brodie Retallick and Luke Romano.
The All Blacks resisted calling in cover, although Chiefs lock Craig Clarke spent some time with the medical team earlier this season - with Hansen saying that in a worst case scenario the likes of Kieran Read or even Adam Thomson could cover in the second row.
Clarke, along with Taranaki's Jarrad Hoeata and Jason Eaton, could play a part if injuries cut down any of the current test locks.
All Blacks manager Darren Shand told stuff.co.nz that they were keeping tabs on the 31-year-old veteran.
“We are obviously pretty keen to track his progress," he said.
“He was down last week, he is in this week and has got the best part of a couple of weeks, and we are hoping that he might get some action in the ITM Cup before we pick the side for the end of year tour."
