All Blacks coach Ian Foster said the All Blacks appeared to be overly excited during the first 15 minutes, and they had provided the Wallabies with some free swings at them due to their lack of discipline.
"The last 15 [when Australia scored three tries] we were disappointing in terms of the way we stepped off the pace, but the middle 50 I was delighted with the composure and the attitude.
"At 33-8 we should have done better but it's a Bledisloe Cup series, we've put a stake in the ground, we're 1-0 up and we're looking forward to next week," he said.
Foster said the start and end of the game were good fodder for a coach to work with leading into the second Test.
"There's plenty to work on in those spells again, it's the first Test in a Bledisloe [series]. It was always going to be a massive Test. They came over here very well prepared and threw everything at us, so the way we came back and squeezed it, and we were doing well at 33-8, it was disappointing.
"We take a lot of pride in how we finish and we didn't finish that well. So there's some things we will take away and work on," he said.
Foster was pleased with the tactical shifts the side made after being too loose starting the game and in trying to move the ball around too much when it wasn't on.
The leadership group had worked it out well as they went through the first half.
"We got a nice formula. I thought it was a great call before halftime to go for that lineout. It was an important try to get to go into halftime," he said after wing Sevu Reece scored from the resulting maul.
While new law variations were involved in the game, Foster said he would assess their impact afterwards, but there had been enough in the All Blacks' faults that were controllable by them.
"If you're offside, you're offside so that's plain and simple and we've got to get better at that," he said.
Foster didn't think the off-night suffered by Australia first five-eighths Noah Lolesio had been a factor in their loss. He said the 33-8 scoreline had suggested it would not have been an issue had he been on target.
He said Australia were a good young team who played with a lot of passion, and they would take a lot of confidence from the way they finished the game, just as the All Blacks would take a lot of confidence from the result.
However, while the Australian side had younger players, so did the All Blacks and there was growing occurring in both sides, he said.
