Henry said yesterday his team had played reasonably well in the 66-28 win over Ireland but that did not mean there would not be team changes and a need for improvement next weekend.
"We need to give players opportunities and see whether they are good enough to be there. We're going to be picking a Tri-Nations squad soon and we do not want to leave players out that have not had a crack," he said.
"Common sense tells us to give players the opportunity to play.
It would be easy to stay on the sidelines and play the same 15 players every week.
But that does not solve the problem we're in.
So we just need broader minds and see how we're going to fix those objectives.
"We need to go up a couple of notches from last night."
That may not be great news for Wales but Henry said his team would get a tougher test than it got on Saturday night from Ireland.
"But it is tough though for these sides.
They have to come from the other side of the world and then have a week to prepare to play a test match.
"But it will be a difficult test match in Dunedin. We have been lucky to have nine days together. I can't remember us being this strong or as well prepared at this time of the year."
Henry said he was pleased with the play of the three All Black new caps, saying Israel Dagg had a big game, and obviously was very talented.
Benson Stanley had fitted in well, while Ben Franks had just continued on from where he had performed in the Super 14.
Henry had been heartened by the performance of some of the backs in the Barbarians side, which lost narrowly to New Zealand Maori on Saturday in Whangarei.
Henry also fired a barb at Welsh coach Warren Gatland, after the former Waikato hooker said Welsh rugby lacked leadership as all the key positions are taken up by overseas talent.
"There's an easy fix to that. Leave them at home. Don't employ them. We can do with them here."
Henry had said straight after Saturday night's game the All Black team had played some outstanding rugby in the first half but, as the game wore, on the error rate increased, which may have been due to some of the players getting tired because of a lack of rugby.
The match was effectively over as a contest when Irish No 8 Jamie Heaslip was sent off for kneeing All Black skipper Richie McCaw after 15 minutes.
McCaw was reluctant to say much about Heaslip's expulsion on Saturday night although he did admit the sending off did change the nature of the game.
But he felt discipline was a vital part of a team's make-up and if a side did not have it, then it should be penalised.
Heaslip yesterday appeared before International Rugby Board judicial officer Michael Cashman and was suspended for five weeks for the incident.
The All Blacks scored nine tries in their record win, in front of a sell-out crowd at Yarrow Stadium.
Jerome Kaino left the field late in the first half with a tight calf while Jimmy Cowan went off at halftime with a slight tinge in the groin.
Cory Jane suffered a similar injury later in the match.
Henry said yesterday the injuries did not appear to be serious.
Carisbrook may see Otago lock Tom Donnelly, the water boy on Saturday night, back in action while the other Otago player in the squad, loose forward Adam Thomson, should also get a run.
Irish captain Brian O'Driscoll, when asked how the Welsh should combat the All Blacks, suggested keeping 15 players on the field would help, along with slowing down their ruck ball.
Franks provided a lighter moment after the game, suggesting he would probably take a knee to the head if it got an opposition player sent off.
