Martin Guptill hit an unbeaten century as New Zealand claimed a five-wicket win at Lord's in the first of three one-day internationals against England.
The opener hit the winning runs with a four to finish 103 not out, while Ross Taylor also contributed 54 in a match-winning partnership of 119 for the third wicket after the Black Caps had slumped to 1-2.
Earlier, England posted 227-9 from their 50 overs, with Jonathan Trott top-scoring on 37 and Tim Southee taking 3-17 to restrict the hosts.
The win was the perfect response after New Zealand lost the Test series 2-0 and the teams will next lock horns in Sunday's second ODI in Southampton.
England, playing in their new red limited-overs kit for the first time, were decidedly off-colour with the bat as one batsman after another got in and then out before he could begin to dominate.
After being put in under cloud-cover on a good pitch, they lost both openers in successive Southee overs and then numbers three and five in a similar sequence to off-spinner Nathan McCullum.
Eight batsmen reached double figures, but Trott's 37 was the top score of a faulty innings against disciplined Kiwi bowling, with Mitchell McClenaghan also taking two wickets.
In reply, James Anderson (3-31) got England off to the perfect start, claiming Luke Ronchi and Kane Williamson for ducks in his first over to leave the tourists reeling.
But Guptill and Taylor steadied the ship and pushed the score on to 121 before Anderson broke up their partnership, having Taylor well caught behind by Jos Buttler off an inside edge.
Grant Elliot came in and hit 27 before being bowled by Graeme Swann and skipper Brendon McCullum holed out to Eoin Morgan off Jade Dernbach for just five, to leave New Zealand on 185-5 and give England a little hope.
But James Franklin notched an unbeaten 16 to help Guptill guide the tourists home.
Fittingly, it was left to Guptill to strike the winning runs, hitting a four off Tim Bresnan - his eighth of an innings which also included four sixes off 123 balls - to ensure he would not be left stranded on 99 not out.
