Smith's perfectly-paced hundred gives Finch winning finish

There was no fairytale finish with the bat for Aaron Finch but he was able to sign off his ODI career with hard-earned 25-run victory as Steven Smith, who will be a contender to be the new 50-over captain, compiled a superb hundred and Australia's bowlers did enough to repel a spirited effort from New Zealand's middle order.

At 112 for 5 chasing 268, after another difficult innings for Kane Williamson, Australia were comfortable favourites but the recalled Glenn Phillips, Jimmy Neesham and Mitchell Santner revived hopes. However, with the target coming within sight, Phillips was caught centimeters from the fine-leg rope by Sean Abbott, who with ball in hand then had Santner caught at long-off.

Smith produced the standout performance with a perfect example of how to overcome tricky new-ball conditions then move through the gears. His 12th ODI century came from 127 deliveries, the slowest of his career, but his second fifty took just 46 balls. It was the first century made in this run of six ODIs against Zimbabwe and New Zealand. In total, the last 20 overs of Australia's innings brought 161 runs.

Shortly before play started there was a minute's silence in memory of Queen Elizabeth II and the players wore black armbands.

Finch announced his ODI retirement yesterday and his final innings came early in the game after Australia were asked to bat. He was given a guard of honour to the middle by New Zealand, and offered a warm handshake by Williamson, then his off-the-mark single was greeted by applause from the weekend crowd. But there would not be a grand sign-off, as he was worked over by some classy swing bowling from Tim Southee who brought one back through the gate to seal a not unfamiliar dismissal.

By then, Australia were already two down with Josh Inglis, recalled to replace the rested David Warner, edging a half-hearted drive against Trent Boult whose outstanding series continued with an opening spell of 6-3-7-1. Smith and Marnus Labuschagne focused purely on survival for a significant period: after 10 overs Australia were 19 for 2 - there were three consecutive maidens from overs seven to nine - and after 15 overs it was 29 for 2.

Steadily, though, the pair started to build. Smith pierced the off side with a cover drive off Lockie Ferguson for his first boundary then consecutive fours followed against Neesham. Labuschagne did not find the boundary until his 62nd delivery. Australia's century came up in the 30th over and also marked a clear shift in tempo, especially from Smith. He launched Southee down the ground to reach fifty and Labuschagne brought up his half-century from 75 balls but could not go much further when he spliced a slower ball from Ferguson to mid-on to end a stand of 118.

Smith and Alex Carey added 69 in 10 overs, with the former dominant. Smith showed his game awareness when he swung Neesham over the leg side for six but noticed New Zealand had too many fielders outside the ring and was signalling the free hit the moment the ball left his bat. His innings ended when he gave himself room against Santner and was bowled. Glenn Maxwell's stay was brief and Carey could not quite cut loose, but Green helped add the finishing touches with two sixes in his 12-ball 25.

Given how the first two games went, it looked a steep chase. A positive opening stand of 49 was broken when Devon Conway drove to backward point where Smith took a low catch. Conway stood his ground but the third umpire ruled the fingers were under the ball. Finn Allen sent Adam Zampa into the sightscreen before his encouraging innings ended when he chipped to mid-on.

The innings then started to seize up in a fashion similar to the second game with Abbott again stringing together maidens. Tom Latham was stumped as the ball deflected off his pads back to Carey and Daryl Mitchell top-edged into the off side. Williamson soaked up 56 balls for his 27, finding the boundary just once, before an awful mix-up with Phillips left a frustrated captain walking off.

However, Phillips and Neesham played sensibly in the face of a climbing asking rate. Phillips produced some stunning strokes over the off side, headlined by a back-foot drive for six against Starc, and though Neesham picked out long-on - Green producing a clever change of pace - Santner kept the target in sight.

It got to 46 needed off 30 which, if not quite in New Zealand's favour due to the loss of wickets, was a very close game. But the visitors could not get it done. Phillips was inches from clearing deep square, where Abbott tip-toed inside the rope, and in the end the game finished with a lot of fruitless swinging from the fast bowlers. New Zealand did not make a half-century in the series.

The victory gave Australia the Chappell-Hadlee series 3-0, although when the trophy is played for again remains uncertain. The two sides are not due to meet in an ODI series under the next FTP running till 2027. New Zealand will now hope they can end their wait for a win against Australia on their soil, dating back to 2011, when they contest the T20 World Cup meeting on October 22.
