New Zealand have ripped through Australia in their World Cup clash to bowl out the Baggy Greens for just 151, leaving them a victory target of 152 in Auckland.
Trent Boult led the way for the Kiwis as he tore through the middle order of the Aussies to take 5-27, his best figures in one-day international cricket.
Michael Clarke won the toss and elected to bat in Eden Gardens, and his decision looked to have been justified in the first two overs as Aaron Finch and David Warner blasted their way to 24-0.
Finch continued the assault with a six at the start of the third, but he was the first victim of the day when he was bowled by Tim Southee.
Warner and Shane Watson calmed proceedings after the early loss and managed to pass the 50-run mark with relative ease before upping the run rate as they notched their 50 partnership.
However, both players were removed within the space of two deliveries as Watson fell for 23 to the bowling of Daniel Vettori, while Southee had Warner trapped lbw for 34 at the start of the 14th over.
Clarke and Smith added 15 runs for the next partnership, but Smith was to fall for four to Vettori as he edged behind to Luke Ronchi.
His dismissal sparked a collapse in the batting lineup as Boult returned to the attack following his opening spell, and bagged the strikes of Glen Maxwell and Mitchell Marsh in the space of three balls as both batsmen dragged on to their stumps.
Clarke was the next man to fall to Boult as he picked out Kane Williamson in the covers for a simple catch, while Mitchell Johnson departed in the same manner for a single. Mitchell Starc continued the disintegration as he was bowled three balls later to leave the Aussies 106-9.
Brad Haddin offered resistance for the Baggy Greens as he saw off the remaining overs from Vettori and Boult before taking the attack to Southee and Adam Milne.
Pat Cummins offered support at the other end as he kept the speedster Milne at bay, allowing Haddin to guide the Baggy Greens past the 150-run mark with a big six off Corey Anderson.
However, Anderson struck with his next delivery to dismiss Haddin for a well-made 43 as Australia were bowled out for 151, their second-lowest total in World Cup history.
