Wellington - New Zealand's hopes of a world record dissolved in the Sydney rain last week but retaining the Bledisloe Cup remains a major motivating factor for the All Blacks ahead of the return match against Australia on Saturday.
Lose their second Rugby Championship encounter at their Eden Park fortress and the Wallabies will only need to draw in the third Bledisloe test in October to regain the symbol of trans-Tasman superiority, which they have not held since 2003.
Win, and the Cup returns to the New Zealand Rugby Union headquarters to a trophy cabinet that has had the women's World Cup and Commonwealth Games men's sevens titles taken out, dusted off and sent elsewhere in the last month.
Such is the reverence with which the All Blacks hold the Cup - the largest sporting trophy in world rugby which reportedly holds the equivalent of 34 cans of beer - they consider it second only to the World Cup on their list of priorities.
Hansen, however, has told his players they are in danger of losing it if they did not improve on their performance from last Saturday's 12-12 draw.
“We didn't play well enough,” Hansen told reporters on Thursday.
“So we have to be honest about that and if we want to retain the Bledisloe Cup we have to go up 10 or 12 notches and get into it.
“We have had an honest review and people in this group have been honest for quite some time so when we don't play well people put their hands up go about working on it and improving and we expect that to happen in the weekend.”
The All Blacks were under intense pressure for much of last week's game, made too many errors in execution and lacked the intensity required to subdue an improving Wallabies pack.
The result ended their winning streak at 17, a top-tier record they now still share with the 1965-69 All Blacks and 1997-98 Springboks.
Hansen has rarely responded to lacklustre performances with wholesale changes, often challenging his players to rectify their errors the following week.
As such, his changes for Saturday's match (kickoff 0735 GMT) have principally been injury-enforced.
Ryan Crotty will make his first test start at inside centre in place of the injured Ma'a Nonu, while Conrad Smith returns at outside centre after pulling out of last week's match to attend the birth of his first child.
Liam Messam starts at blindside flanker in place of the injured Jerome Kaino, who will be out for up to six weeks with an elbow problem.
Wallabies coach Ewen McKenzie also resisted the urge to tinker with his side, retaining the same 23-man squad that pushed the All Blacks to the brink last week.
His gamble to give Kurtley Beale the starting flyhalf role did not quite pay the dividends he had hoped but it did not fail and the New South Wales Waratahs' utility will be keen to stamp his mark on the game in better conditions.
McKenzie's biggest concern will be whether his tight five will be able to match the home side's scrum power after they were put under intense pressure last week, even though referee Jaco Peyper's whistle suggested otherwise.
“We can't afford to have a bad day at the office,” McKenzie told reporters in Sydney earlier this week.
“So you've got to make sure you aren't going backwards. You have got to be able to get parity at least and then you've got a platform to play with.”
