The Chappell-Hadlee Trophy might have been decided on Thursday night in Auckland but Australia will be keen to maintain its momentum in the final match in Wellington on Saturday ahead of next week's start to the two-Test series.
After dropping the opening match of the series Ricky Ponting's men have responded superbly with three successive wins, claiming the past two without vice-captain Michael Clarke following his return home, and they'll be keen to put an emphatic stamp on the contest with a 4-1 win.
Australia surrendered its world No.1 ranking in the one-day arena when it went down 4-1 to South Africa on home soil in January last year and followed that series with a 2-2 draw against New Zealand and then a 3-2 loss to the Proteas in South Africa.
But since then the three-time defending World Cup champions have swept all before them, beating Pakistan 3-2 in the UAE and England 6-1 in the UK in the lead-up to taking out the Champions Trophy before also seeing off India 4-2 away and Pakistan (5-0) and West Indies (4-0) at home.
With the series now decided the tourists will probably hand fast bowler Clint McKay his first start of the series with the likelihood that he'll be part of Australia's attack for the Test series, which gets underway in Wellington on Friday, March 19.
George Bailey could also get a run after being rushed to New Zealand earlier in the week as Clarke's replacement.
Mitchell Johnson has responded impressively to being a target of the Kiwi crowds following his run-in with Scott Styris in the first game, claiming 4-54 in game two and backing it up with hauls of 3-41 and 2-40 as the Black Caps have been restricted to totals of 253, 245 and 238.
The pattern throughout the series has seen the team batting first getting off to a fast start before losing wickets and much of its momentum, with the chasing team winning three of the four games so far.
That being the case Daniel Vettori will be desperate to bowl first because the Kiwis much prefer chasing a target rather than trying to set one as they've been obligated to do in the past two games after Ponting has won the toss.
Ponting enjoys grinding opposition teams into submission once Australia gets on top so expect no let-up from his side in the final game.
