New Zealand has won a last-gasp thriller in Dunedin to take a 2-0 series lead.
The contest turned from a one-sided snore-fest into a rollercoaster finish at the death on the back of an explosive innings between Marcus Stoinis and Daniel Sams.
Sams (41 from 15) and Stoinis (78 from 37) went bananas in the final seven overs, with their extraordinary partnership worth 93 runs from just 37 balls.
The pair had Australia with victory in sight heading into the final over needing 15 runs to win.
Both stars were caught on the fence in the final over, as the Kiwis held their nerve to win by four runs.
The Kiwis earlier battered the Aussie attack to reach 7/219 from their 20 overs.
Australia looked dead in the water before Sams and Stoinis arrived at the crease, but their brilliant innings' could only push Australia to 8/215. Sams hauled out in the deep in the first ball of the final over.
His cross-bat slog off a full-toss hit high on the blade but was just 2m short of clearing the rope.
He was caught by Glenn Phillips off the bowling of Jimmy Neesham.
Even with the wicket, a Marcus Stoinis six left Australia needing nine runs from the final two balls.
Stoinis, however, followed Sams in being caught on the fence in the very next ball to leave Australia devastated at the end of an extraordinary fightback.
Stoinis reached his 50 from just 22 balls as he and Sams breathed life into the Aussie chase.
Sams at one point struck four sixes from five balls.
The pair came together with Australia dead and buried at 6/113 after 13 overs. It looked grim for Australia, but the contest wasn't over until the very final ball.
