"I haven't put too much thought into it."
Cruden said the selectors' decisions during next months' four-test tour would have no bearing on his decision. That is likely to be the time when coach Steve Hansen attempts to persuade the 27-year-old that he should stay.
"We haven't sat down and had a big discussion," Hansen said. "He knows that we want him to stay and that discussion will probably happen when we are away. He's not going to make that decision overnight.
"He's a big part of who we are and what we do. He's in our leadership group and he's a good enough player to be a starting test player so we don't want to lose him. That's going to be a decision that he'll make and he'll make it for what's right for him and his family."
Cruden, who hasn't played for the All Blacks since hurting his groin in the test against the Pumas in Hamilton in September, will likely come on in the second half of the test against the Wallabies on Saturday. His pace and tactical nous, alongside the power of fellow reserves Ardie Savea and Malakai Fekitoa, could trouble Michael Cheika's side should they still be in with a chance.
After a frustrating recent time of it, being part of a world record victory would be a big boost for Cruden before the tour of Chicago, Rome, Dublin and Paris. But big decisions remain.
