Ireland arrived in Wellington today buoyed by Munster and Leinster's recent successes but minus captain Brian O'Driscoll, scrum-half Eoin Reddan and full-back Geordan Murphy.
O'Driscoll is due to arrive within the next 48 hours after leaving the Ireland camp prior to their win against the Barbarians earlier in the week because of the death of a close friend.
Reddan, of Wasps, and Leicester's Murphy were involved in the Guinness Premiership final, won by the London club yesterday, and stand-in coach Michael Bradley is hoping to have them in training by Thursday at the latest.
Despite there being less than a week until the Test against New Zealand, Bradley felt the players' late arrival would not be too disruptive for the squad.
"Brian was with us up until the Barbarians match, so he's obviously very familiar with what's happening," Bradley said.
"Geordan and Eoin were with us for the Six Nations so systems are in place. They are smart rugby players and they'll do their homework for a match on Saturday. It's not really an issue for us."
Next weekend's match will not be played under the experimental law variations (ELVs) which have been in use during the southern hemisphere's Super 14 competition.
But Bradley was unsure how much of an advantage that would be for Ireland.
"We don't know. We have the advantage of not transferring to the ELVs, in terms of the coaching side of it and getting the players thinking in terms of the advantage and disadvantage of playing those rules," he said.
"On the other side, having looked at Super 14 matches, the amount of time the ball is in possession and the speed at which the game is played is now considerably faster than what it is played without them (the ELVs).
"So we are going to have a meeting of the two (different styles) and it will be the first game played under those conditions, so we will see how it goes."
Ireland will face a different looking All Blacks team at Westpac Stadium on Saturday after Graham Henry announced six new caps in his squad of 26 for the Tests against Ireland and England and the Tri-Nations competition.
Only 16 members of the squad that travelled to last year's World Cup in France have been retained with most of the remaining 14 players from that 30-man squad now playing their rugby in the northern hemisphere.
But Bradley felt the changing of the guard did not necessarily mean the All Blacks would be a weaker side.
"I've never ever seen a bad All Blacks side. New Zealand have a tremendous tradition in rugby and consistently produce excellent players," he said.
"We're probably at a little bit of a disadvantage on the basis that you will have (new) players playing for the jersey, for New Zealand, on Saturday and as always those players will lift those other players around them so it should be a fascinating game."
England flanker James Haskell insists he will be pushing as hard as possible to be back from a toe injury in time to make his case for a spot in Eddie Jones' side looking to defend their RBS 6 Nations title next year.
