New Zealand captain Daniel Vettori conceded that Australia were simply "too good" after his side went down to a six-wicket defeat at the Adelaide Oval.
The defeat leaves the Chappell-Hadlee series fascinatingly poised at 2-2 heading into the final match of the series at Brisbane on Friday.
After batting first in the fourth ODI, Vettori's side managed just 244-8 from their 50-over allocation, a total the Black Caps skipper admitted was unlikely to be a winning one.
"We needed to get around the 270-280 mark but it was still a total that if we came out and bowled and fielded well that we possibly could have defended," he said.
"But unfortunately today Australia were too good."
Ross Taylor continued his fine form with the bat with a quickfire 76 off 71 balls for the tourists, however he lacked support from the middle-order as Australia kept it tight with the ball.
Chasing the target, a 115-run partnership between Hussey brothers David and Mike took the game away from New Zealand before the latter finished the game in style with a six.
Vettori now admits his side must come up with a plan to nullify the threat of Mike Hussey after the 33-year-old has continued to torment his bowlers throughout the series.
He said: "He (Mike Hussey) has played really well. He has controlled the innings in all four games really and that's probably been the difference between the two sides - his ability to manipulate the scoring and keep the striker at the other end going.
"That is obviously something we are going to have to deal with in Brisbane.
"I think if Grant Elliott and Ross Taylor had continued their partnership then a little bit of momentum would have gone our way."
"And just with the ball, I don't think we started as well as we have done in the first two games and basically that has let us down in the last two," he added.
"That's the thing we need to improve on to give us a chance in Brisbane.
"I suppose losing two in a row always knocks a little bit out of you but it is a do or die game and that is pretty exciting and I think that is what everyone wanted to see and probably how it was meant to be."
Ricky Ponting also heaped praise on the performances of the Hussey brothers and admits he cannot wait for the Brisbane decider on Friday.
He said: "I think we did things really well early on with the ball, their scoring rate never really got away from us, they probably snuck away a little bit in their powerplay in the last couple of overs but I always thought 244 was a chaseable total.
"Mike Hussey is in the runs again and I thought David Hussey played beautifully tonight - that's a really good sign for us going forward.
"The bowlers are getting better game by game as well so I can't wait for Brisbane."
