"That wasn't what Izzy intended but that's the way it came out," Fox said. "And that's a perfect example of why you don't have a conversation with them on the phone, because they are emotional.
"Izzy was great and he left [the meeting] with a very clear message. He understands what he has to do. And he's only 27. This is a bump in the road for him.
"I wouldn't be surprised if you see Israel Dagg on fire for Hawke's Bay this year, and there's every chance he'll be back in the All Blacks next year."
Piutau, on the other hand, will have to wait considerably longer for a return to that stage, but Foster hoped it would one day arrive. While the Blues fullback will take up a two-year contract at Ulster in July 2016, time is certainly still on the 23-year-old's side.
"Hopefully he'll come back better and restake his claim," Fox said. "Hopefully [the whole group] will go away thinking they've got hope, because that's certainly what they were left with — that their All Blacks careers aren't over, that there will be other opportunities."
With a host of senior players set to leave New Zealand rugby following the World Cup, that opportunity could come sooner rather than later for many of the men who missed out.
Only Andy Ellis, Cory Jane and Jeremy Thrush are on the wrong side of 30, meaning players like Nepo Laulala and George Moala have their whole careers ahead of them. And others, such as Ryan Crotty and Lima Sopoaga, hardly have to squint to see vacancies opening in their positions in 2016.
Of course, any of the 12 could instead be called on during the next seven weeks and, with injuries a reality of such an arduous campaign, that was another reason for an open and honest dialogue during the week.
"We're going to keep in touch, because anything could happen and we might need them on a bird," Fox said. "We need them to keep working on the things that are perhaps part of the reasons why they haven't made the group, so that if we do need them they're in better shape and we're going to get a better athlete."
Fox confirmed, however, that none of the 12 will venture to the UK unless they were called up.
