New Zealand have continued their hot streak in the short form of the game by beating Australia by 55 runs to win the Chappell- Hadlee trophy two games to one in Hamilton.
This is their third series win in the limited overs format in two months after victories against Sri Lanka and Pakistan.
Batting first for the third straight game, the Kiwi openers in Brendon McCullum and Martin Guptill looked to get their side off to another quick-fire start.

McCullum who was playing his last ever 50-over game for his country, was his normal intimidating best.
The openers had put on 84 for the first wicket before McCullum fell to Mitch Marsh. He scored 47 runs of just 29 balls which included six 4's and three 6's.
Guptill top scored with 59, before he was dismissed by leg-spinner Adam Zampa.
Grant Elliott then attempted to take control of the innings sharing a 40-run stand with Henry Nicholls, and then a 50 run stand with Corey Anderson.
However, when Anderson fell with the score on 223, their innings fell in a heap.
They lost their last five wickets for nine runs in a little over two overs to be all out for 246 in the 46th over.
It was well before par as at one stage, they looked to be on target for well over 300.
Marsh was again superb with the ball taking 3-34 while John Hastings, Josh Hazlewood and Scott Boland each took two wickets.
In reply, the visitors lost key man David Warner early in the run chase for 16.
Usman Khawaja looked composed again, but he fell for 46 - failing to capitalise from a great start for the second straight game.
Things didn't get much better when Steve Smith fell to leg-spinner Ish Sodhi for 21, and two balls later he got another wicket claiming a horribly out of form Glenn Maxwell for zero.
It left the visitors at 4/94 and in trouble.
A 59-run stand between George Bailey and Marsh put them back on track.
However when the two set batsmen fell within 11 runs of each other it was the beginning of the end.
The last four wickets fell for 37 runs and New Zealand begun celebrating a one day series win against their Trans-Tasman rivals for the first time since 2007.
Sodhi was the man of the match for his pivotal spell in the middle part of the innings.
The teams now contest a two test match series.
