Brett Lee capped an "irresistible" case for a Test recall by breaking the 100-mile-an-hour barrier as Australia kicked New Zealand while it was down.
The world champions signed off on a 5-0 one-day series clean sweep in menacing style at Napier's McLean Park with a 122-run thumping.
Captain Ricky Ponting broke a string of records with a spectacular unbeaten 141 in Australia's 5-347 - it's second highest one-day total across the Tasman.
But it was Lee who had the capacity crowd gasping as he delivered a 160.8kph thunderbolt in the first over of the New Zealand (8-225) reply.
It was the second of two 160kph (100mph) missiles hurled at opener Craig Cumming and the fastest ball the blond tearaway has ever delivered.
Only Pakistani spearhead Shoaib Akhtar has officially recorded a faster reading - 161kph against NZ in Lahore in 2002.
"I was quite pleased to see that it was that quick because I was quite late on it," said Cumming after the match.
"The first over did seem to go by pretty quickly and I was quite pleased when I went down to Flem (captain Stephen Fleming) and he said it was probably the quickest it gets, and that was a bit of a relief to be honest."
Ponting admitted he had little reason to resist Lee's Test claims except for the form of his incumbent pace trio of Glenn McGrath, Jason Gillespie and Michael Kasprowicz.
Not to be outdone, Kasprowicz, the man who would lose out if Lee was promoted, was Australia's best bowler in taking 3-36 off 10 tight overs and unluckily missing a first-over hat-trick.
"It certainly hasn't made it easier," Ponting said. "All the fast bowlers are bowling very well.
"Brett today bowled extremely fast ... but his control has been the most pleasing thing as well. He's bowling as well as he's bowled, probably, ever.
"All I know is if you look back at what the (current Test) three have done ... you can't take anything away from those guys and you have someone like Brett knocking at the door who is fairly irresistible at the moment.
"He just has to bowl the same way in a Test match and he'll do well.
"If he happens to play a Test you can give him the new ball and you know he's more than likely going to do some damage with it swinging early."
Lee (1-34 off 10 overs) had the Black Caps on the back foot immediately by letting rip with deliveries clocking 143, 151, 158, 158, 160 (wide), 160.8, 158.
Lee's fastest before today was 160kmh at Port Elizabeth during the 2003 World Cup.
Kasprowicz dismissed Fleming (35) caught behind with his second ball and then had James Marshall playing on next ball before appealing confidently for LBW against Craig McMillan.
McMillan was struck in front by a ball that was zeroing in on middle-stump but umpire David Shepherd gave him the benefit of the doubt.
McMillan continued to ride his luck, including escaping a disputed diving Andrew Symonds catch when on 34, to top-score with 63 off 69 balls.
The victory takes Australia to a record high of 140 points in the International Cricket Council's championship standings.
It also inflicted NZ's first 5-0 series whitewash on home turf.
Ponting earlier belted 10 fours and five sixes in his classy knock, taking up the slack after Adam Gilchrist smacked 91 (61 balls) on being sent in by Fleming.
The skipper finished his 17th ODI century and the tourists' innings in style with two towering sixes off the last two balls to receive a standing ovation from the crowd of 10,817.
It broke the previous highest score made in NZ by Glenn Turner (140 not out against Sri Lanka in Auckland in 1982-83) and surpassed the highest by an Australian against NZ (138 not out by Greg Chappell in Sydney in 1980-81).
The world champion's total was also the biggest one-day score amassed at the Napier ground, easily eclipsing the previous best of 6-277 set by NZ against Pakistan in 1984-85.
The depleted Black Caps injury woes continued in the fourth over with all-rounder Chris Cairns pulling his hamstring in the field, preventing him from playing a part with bat or ball.
