Debutants step up to the plate

All Blacks coach Steve Hansen is hailing the string of debutants after blowing Ireland off Eden Park.

New Zealand's turned on the style in its first test since winning the Rugby World Cup with a sublime 42-10 victory.

21-year-old Julian Savea scored a hat-trick on debut but was supported by fellow first-time All Blacks in lock Brodie Retallick and halfback Aaron Smith.

"Brodie doing the hard work, Azza at halfback was simply outstanding, he made some great decisions but his clearing of the ball was fantastic, and the young man on the wing was not too bad either, three tries on debut's pretty handy."

Savea is shifting the praise for his efforts.

"I gotta give the credit to the boys inside me, they played well and gave us good quality ball."

All Blacks captain Richie McCaw says he was delighted for the youngster.

"You're always going to be a bit nervous getting out there and nothing better than crossing the line to calm you down but you get across the line three times, from our point of view happy to see five points under the dot."

And while Hansen's satisfied with where his side's at, Irish coach Declan Kidney has numerous injury concerns to his front row with Cian Healy picking up a shoulder injury.

He says Mike Ross and Declan Fitzgerald are still coming back from injuries.

The Irish won't travel to Christchurch for the second test until Wednesday.
