England 226 for 7 (Livingstone 95*, Curran 42, Boult 3-37) beat New Zealand 147 (Mitchell 57, Topley 3-27, Willey 3-34) by 79 runs
Southampton: England comfortably beat New Zealand by 79 runs to level the one-day international series in a rain-affected encounter at Southampton on Sunday.
The game was reduced to 34 overs per side and England slipped to 55-5 having been put in to bat.
But Liam Livingstone's unbeaten 95 from 78 balls, in a seventh-wicket stand of 112 with Sam Curran, helped them recover to 226-7.
Reece Topley then took 3-27 as New Zealand fell to 147 all out.
Seamer Trent Boult made an immediate impact upon his return to the side, having not played an ODI for almost a year, reducing England to 8-3 as Jonny Bairstow, Joe Root and Ben Stokes added just seven runs between them.
Jos Buttler and Moeen Ali led a brief middle-order recovery before Livingstone and Curran, who made 42, set a formidable total.
England's bowlers started brilliantly, David Willey bowling the dynamic Finn Allen with the second ball of the Black Caps' innings.
Mitchell's resistance kept them in the game throughout a measured start to the chase but England kept the pressure on throughout and New Zealand lost their last six wickets for just 36 runs.
The four-match series continues at The Kia Oval on Wednesday.
