Opener Martin Guptill has cracked the fourth-highest score in one-day international cricket to lead New Zealand to a series-sealing 86-run win over England in Southampton.
Guptill compiled an unbeaten 189 in the tourists' 359-3, a total England never looked like reaching despite a century from Jonathan Trott as they were dismissed for 273 off 44.1 overs on Sunday.
Following their five-wicket win at Lord's on Friday, New Zealand go two-up in the series with one match to play at Nottingham on Wednesday.
Guptill has dominated the series and is yet to be dismissed, steering the Black Caps to victory with 103 not out at Lord's.
His 189 off 155 balls is comfortably the highest score by a New Zealander, surpassing the previous best of 172 by Lou Vincent against Zimbabwe in Harare eight years ago.
He equalled West Indies' great Viv Richards in reaching the highest individual ODI score against England.
Only four players have scored more in 3361 ODIs, a list topped by 219 from India's Virender Sehwag against the West Indies in 2011.
Guptill paced himself superbly, starting patiently and taking 111 balls to bring up his fourth ODI century. He gave one chance when he was dropped on 13 by Trott.
The 26-year-old exploded over the closing stages, finishing with 19 fours and two sixes as he helped New Zealand score 126 runs from their last nine overs.
Captain Brendon McCullum blasted an unbeaten 40 off 19 balls at the death while Kane Williamson (55) and Ross Taylor (60) also played key support roles following the early departure of Luke Ronchi (2).
All of the English bowlers were punished.
Seamer Jade Dernbach suffered most heavily with 0-87 off 10 overs while James Anderson (2-65) equalled Darren Gough's England record haul of 234 ODI records.
It was New Zealand's sixth-highest score in ODIs, with those above it coming against lowly-ranked nations Zimbabwe, Ireland and Canada.
Their previous best against England was 340-7 at Napier in 2008.
As was the case at Lord's, England's batsmen established themselves but failed to push on, aside from Trott, who was left stranded on 109 not out off 104 balls.
They maintained a decent run rate but ran out of wickets, sliding to their first home series loss since 2009.
Pace bowler Mitchell McClenaghan took 3-35 off 8.1 overs, whipping through the tail in his second spell.
New ball partner Kyle Mills (1-55) was tight again at the top of the innings, bowling England captain Alastair Cook for 34 in the eighth over to start the rot.
