Henry was happy with the first hit-out this season, as the All Blacks beat Fiji 60-14.
"To score 60 points was pleasing and the Fijians are going to surprise a few sides.
"We played well in patches and scored some good tries. To score those tries you have to do the build-up well and sometimes when we got the opportunity we did not do the build-up."
Henry said the players had only had a week together and had got through plenty of work.
Playing the Springboks next Saturday would heighten the intensity for the side, he said.
"But we have plenty to work on. Fiji played particularly well but we need to step up from here."
Henry had praise for first five-eighth Colin Slade, and assistant coach Wayne Smith said Slade probably could not have played any better, considering his recent lack of football.
The All Blacks were scoreless in the third quarter, and captain Richie McCaw said the big concern during that period was a lack of performance at the breakdown.
"We did not do those little jobs at the breakdown and those little things were frustrating. We just didn't get the execution right and turned the ball over a couple of times," he said.
"There are things when you come together you have got to take for granted. We wanted to get our own game going, and the opportunities came along but we did not take those at times."
Loose forward Adam Thomson said it was a typical first-up performance.
"There were combinations that needed a bit of tweaking. Some things worked well and then [there were] things that needed to be worked on," he said.
"I'm just happy be get back out there. It's been five weeks since I last played and I just wanted to get back out there, make some tackles and get into my role.
"You've got to give credit to them [Fiji]. They played a big physical game and they had a good defence and we knew they would."
Thomson said he was slightly embarrassed about scoring his try, saying he stole it off a front-rower.
Thomson led the tackle count for the All Blacks with 13 and never stopped running.
Jarrad Hoeata made a test debut of just over 50 minutes before he was forced off because of a leg injury, which he tweaked running the ball up in the first half. He was still thrilled to have played his first test.
"It just felt a little helter-skelter early on ... but it was probably always going to be like that, first test and all. We just couldn't seem to get quick ruck ball at all but we still beat them by 50-odd points."
