Kevin Pietersen's sixth one-day international hundred helped put England 1-0 up in the NatWest Series at Chester-le-Street.
Pietersen struck an unbeaten 110 in England's 307 for five, a total far in excess of New Zealand's reach.
Daniel Vettori's tourists were eventually dismissed for 193, Stuart Broad's removal of both openers key to England closing out the game.
Pietersen hit three sixes - two of them 'left-handed' after switching to a new guard in the bowler's delivery stride - and eight fours in his scintillating innings.
Owais Shah cracked a brisk 49 during a manic last 10 overs while captain Paul Collingwood overturned a chronic lack of form with 64, at a run a ball.
