New Zealand were relieved to come away from Eden Park with a victory after the heroics of Marcus Stoinis for Australia, says Neil Broom.
The Black Caps set their visitors 287 to win the opening one-day international of the three-match series, Broom top-scoring with 73 from 75 deliveries in the middle order.
Trent Boult, Tim Southee and Lockie Ferguson looked to have the Kiwis cruising to victory as Australia slumped to 67-6, but Stoinis gave them hope.
He hit a superb 146 not out - including nine boundaries and 11 maximums - and shared late partnerships with James Faulkner, Pat Cummins, Mitchell Starc and Josh Hazlewood as the tourists neared the target.
With four overs to bat they needed 19 runs to win and successive sixes off Southee brought that down to just seven, but as he tried to farm the strike Hazlewood was run out at the bowlers' end to hand New Zealand a 1-0 lead - much to the relief of Broom.
"Halfway through you think you're coasting, then for Marcus to play a knock like that and almost bring it home is pretty special," he told a media conference.
"He's obviously got that power game and he was taking on the small boundaries, it was spectacular hitting. You feel for him but we'll take the win.
"When guys are going like that they can pull anything off, chase down whatever. It looked like it would be his day.
"I was getting a bit twitchy down there [at long-on]. We're just relieved. It was pretty cool for it to come down to the wire."
Captain Kane Williamson produced the decisive moment as his throw caught Hazlewood short of the crease, sealing a six-run triumph.
It was third time lucky for Williamson, having dropped Stoinis on 91 and then missed a chance to run him out on 128.
He added: "It was well bowled and for him to hit the stumps after missing previously and that dropped catch, he'll be happy with that I'm sure."
