Conrad Smith scored two of New Zealand's nine tries against Ireland
Ireland coach Declan Kidney admitted his side had suffered a "horror show" in the first half as they crashed to a 66-28 defeat against New Zealand.
The All Blacks ran in five tries for a commanding 38-7 by the interval.
"We gave away a lot of soft tries and missed tackles. We will have to have a long hard look at that," said Kidney.
"The players picked themselves up at half-time, you saw that, and we managed to keep the ball a little better in the second half."
All Blacks captain Richie McCaw was happy with his side's performance, especially debutants Israel Dagg, Benson Stanley and Ben Franks.
"The way we started the game, we are pretty happy with," he said.
"There is always going to be stuff to work on but I'm pretty happy.
"All the boys who played their first game had a pretty good day."
