Matt Henry felt New Zealand "came to the party" with bat and ball in a crushing 158-run defeat of Australia in the first one-day international at Eden Park on Wednesday.
The Black Caps edged to a one-wicket victory over Australia in a World Cup clash in Auckland last year, but it was a very different story in the opening game of the three-match series.
Martin Guptill (90) and Brendon McCullum put on 79 for the first wicket, while Henry Nicholls (61) and Mitchell Santner (35 not out) were also in the runs as New Zealand posted 307-8.
Devastating bursts from Henry (3-41) and Trent Boult (3-38) reduced the tourists to 41-6 in reply, with Matthew Wade (37) and James Faulkner (36) then putting on 79 for the seventh wicket before they were skittled out for only 148.
It was the first time Australia had been dismissed for less than 25 overs in an ODI and Henry reflected on a job well done.
He said: "The start Guppy and Brendon got us off to was awesome, we then established partnerships in that middle period and got to take the pressure off so we could get to a total that we thought was defendable.
"As a bowling group we wanted to take a lot of pressure off up front with the new ball and bowl in partnerships. I think that's what we did today.
"Everyone came to the party, Milney [Adam Milne] came in with some good pace as well and it carried on right the way through."
But Henry knows Australia, who beat New Zealand in the World Cup final last year, have the quality to hit back.
He added: "I wouldn't say they folded, it just came down to a half an hour period where things really went our way.
"They're still a great side, with a very strong batting line-up and I think that showed with the way Wade and Faulkner still created a lot of pressure. It's just cricket, it's one of those things and it can turn pretty quickly."
The two sides travel to Wellington for the second game of the series on Saturday, but Australia all-rounder Faulkner will play no part in the next two games after suffering a hamstring injury so Marcus Stoinis comes into the squad.
