The Black Caps have ripped through Australia to claim a 159-run win and a 1-0 series lead at Eden Park in Auckland.
After a batting display that fell short of early expectations, the New Zealand attack tore through an Australian line-up chasing down 308 to win.
Matt Henry had two wickets within the first six overs, removing Shaun Marsh before cleaning bowling Australia captain Steve Smith.
David Warner, who fared well in Australia's World Cup pool match at Eden Park last year, was caught LBW by Boult, and sent from the field to a chorus of boos from the Auckland crowd.
Australia couldn't catch a break after George Bailey was dropped by Corey Anderson, before the Black Caps all-rounder made amends two balls later to make the catch at the second time of asking, giving Henry his third wicket.
With the Eden Park crowd already in a rapture, Kane Williamson's stunning one-handed catch to remove Maxwell and peg Australia back to 40/5 took the atmosphere another level.
But it was departing captain Brendon McCullum's catch of Mitchell Marsh in the slips that received the biggest cheer and had Australia reeling at 41/6.
Mathew Wade and James Faulkner brought some respectability to Australia's innings, notching a 79-run partnership until Wade skied an Anderson delivery to Williamson in deep.
Faulkner followed shortly after, chopping an Adam Milne delivery on to his own wickets before Mitchell Santner took the last two wickets with his first balls of the night.
Earlier, having lost their 15th consecutive toss in one-day internationals in Auckland, the Black Caps wasted no time setting a target in the first Chappell-Hadlee Trophy game. Brendon McCullum and Martin Guptill got stuck into the Australian bowlers early, the skipper bringing up his 6000th-run milestone in the process.
McCullum (44) was bowled by James Faulkner, with Williamson going for a duck as Australia attempted to slow New Zealand down.
But it was Guptill who found himself freeing the arms, smashing 13 boundaries before he was eventually run out for 90.
Guptill and Henry Nicholls (61) had Black Caps fans optimistic after Williamson was uncharacteristically sent packing for a duck, with their middle order partnership.
But Australia's attack did well to restrict New Zealand's total to 307 as Grant Elliott, Corey Anderson and Luke Ronchi failed to fire.
However, New Zealand's lower order once again finished strongly to set up a competitive run chase.
