Hansen, who has four children, said he was expecting a boy of about "six pounds" as Lee-Ann, due to give birth in a fortnight, had gone into labour early. He was not expecting "Stephen" to feature in any of the names.
Hansen was also quick to turn as much pressure as he could back on Australia, saying of the Wallabies: "They're under a lot of pressure, which they're putting themselves under, talking about having to win the Bledisloe Cup, they haven't won the Bledisloe Cup, 'this is our year' - I find that interesting. It's no different to any other year. There's two teams in the competition and one of them will win it and one of them will lose it."
On arriving in Sydney on Thursday, he continued his theme, saying: "Every week there's pressure on us to win, that's what test rugby is all about. You're expected to win, whether it's one test, 18 tests, or 25 tests, the result people want is the All Blacks to win, from our point of view."
The All Blacks are expected to win every test, as Hansen said. Losses are always tough to take for a New Zealand public, especially during World Cups. A defeat here, though, will also reverberate around the world.
Depending on the result, the All Blacks will neither celebrate nor mourn unduly. Their next assignment is only seven days away, the return encounter against Australia at Eden Park.
