That they managed to do has left Hansen in good spirits about where this team is heading.
Losing around 900 test caps as they did after the World Cup was tough and when 148 were tied to captain Richie McCaw, no one had any right to believe the transition would be seamless. Not that it was, but it was as good - probably better - than Hansen expected.
To come home with just the one defeat, is above expectation. Asked what pleased him most, Hansen said: "The character the team showed at times and the skill factor.
"We are well known for being a highly-skilled team but at times we've had to show composure and the key thing I'm happy with is that the leaders have stood up. We have lost Richie, Conrad [Smith] and Ma'a [Nonu] and people like Kevvy [Mealamu] and Woody [Tony Woodcock] and those guys in the pressure cooker of a test match have been ice cool and calm and have allowed the team to come out the other side.
"To lose them and still be able to do that the majority of the time, other than probably Chicago, has been satisfying. I think we got asked even more questions [in the last four weeks]. We got asked some in Chicago and afterwards I think when we discussed it, they learned quite a bit and I think they responded really well in both Italy and Dublin. And then coming off a win like we did in Dublin and having to front up against a good French side was really pleasing."
If there was an added benefit - a little extra bonus Hansen wasn't expecting - it was the emergence of Rieko Ioane and Scott Barrett as players of considerable potential.
Both surpassed expectation and played their way deeper into the selectors' thinking for 2017.
"At the start of this tour, we wouldn't have thought Rieko would have been playing in this game," says Hansen. "He stood up and played well. He has got the potential to be a very good rugby player. Scott Barrett got an opportunity through the injuries to [Brodie] Retallick and [Sam] Whitelock and he is the only guy who played all four games. He should be proud."
