The second test of the series between England and the All Blacks will have plenty riding on it after a seesawing opening encounter at Eden Park on Saturday night.
All Black coach Steve Hansen believes his side can improve by 30% to 40%, while English coach Stuart Lancaster has the difficult job of picking a team from a full-strength squad and possibly dump players who put in a brave shift in Auckland.
Regardless of Lancaster's selection, Hansen is expecting another lion-hearted effort from the men in white.
''They won't change how they play. Their game plan may vary from one to two degrees but, basically, it will be what we got tonight. Maybe different, fresher faces, but I don't know,'' Hansen said.
''With such a short period of time to get everyone gelled together, if we start panicking too much about what England are going to do and change everything we are doing, we are going to recreate what we did this week, which is a lot of learning and clutter.
''This week there has been a lot of work to do - mental, cerebral work. Next week there won't be as much work, as we have done it this week, so hopefully that allows us to be faster, sharper and more energised.''
Hansen said the All Blacks had shown plenty of rustiness in the narrow 20-15 win on Saturday night.
''It was a physical, dour sort of game with a lot of errors from both sides, really. I put some of ours down to rustiness ... but that also comes from the opposition.
''We have got a lot of work to do between now and Saturday and we're really looking forward to that.
''I think if we gave ourselves a mark, we were at about 70%, and that is just going to get back to where we should be. So we are going to have to be 30-40% better than we were today.''
First five-eighth Aaron Cruden opened the game up with about five minutes left.
With the scores locked at 15-15, he tap-kicked a penalty 35m out when most expected him to kick for goal.
Cruden's decision was backed by both coach and captain.
''I thought it was a good decision,'' Hansen said.
''It was one of those games where someone had to take it by the scruff of the neck and say, 'Right, we have to stop what we are doing and do something different and have a crack at you.'
"One person made a decision to change how we were playing in a vital moment and that is what rugby is about.''
All Black captain Richie McCaw did not make the call but supported Cruden, saying players needed to play what was in front of them.
The game did not have much flow, with plenty of errors and too many injury breaks and stoppages.
Hansen said that was annoying but had no impact on the side's performance.
There were too many dropped balls from the home side and it kicked the ball away too often in the first half. Highlanders centre Malakai Fekitoa had 20 minutes off the bench for Ma'a Nonu in his test debut and showed plenty of energy against a tough English defence.
Lancaster said his English side was desperately disappointed to lose after what had been a tremendous effort.
It left him with a tough task picking the side for the Dunedin test, when a host of players who arrived late for the tour will become available.
''Through no fault of their own, there are a large group of them who had the shirt and are sitting in the stand,'' he said.
''So they have to be taken into consideration as well as those who played so well today. But for me it is about the bigger picture.
"It always is, I suppose. We are building towards the World Cup in 2015 and making sure people get experiences out here.''
• A lack of match fitness means Kieran Read is in doubt for next Saturday's test. All Black coach Steve Hansen hinted yesterday he could take a cautious approach to the return of the No8, who has played only once since suffering concussion while playing for the Crusaders against the Chiefs in April.
If Read is ruled out again, Jerome Kaino will retain his place at No8.
Israel Dagg could also be a doubtful starter after a thigh and knee problem cut his night short at Eden Park.
However, Julian Savea could be available to return to the left wing. Hansen said Savea's knee was improving well.
