All Blacks coach Steve Hansen has said he doesn't want to give away too many secrets to the Irish, but Declan Kidney's men can probably start preparing to face Sonny Bill Williams in Saturday's first test in Auckland.
After naming his squad for the three-test series, Hansen hinted it was likely Ma'a Nonu and Tamati Ellison, who have both come into this Super Rugby season without a break following club duties in Japan, will be rested.
That will result in Williams, the form second-five in New Zealand, wearing the No12 jersey for the All Blacks at Eden Park. Highlander Ellison, recalled to the squad after playing his first and only test against Italy in 2009, is a midfield utility player and probably would have hoped for a place on the reserves bench at best.
Hansen said of a rest for Nonu, who has looked jaded in a poorly-performing Blues side after moving from the Hurricanes: "We'll just have to wait and see about that. We've got another guy [Williams] playing extremely well at the moment so that gives us some really good options to perhaps not have to play him if we don't need to. We'll make those decisions over the next few weeks."
The new All Blacks coach was more forthcoming about a possible rest strategy when asked to comment on Ellison, however.
