The English women completed their comeback from 2 1 down to clinch the series 3 2 with a five wicket win at Bert Sutcliffe Oval in Lincoln.
It followed their 2 1 twenty20 series win, although the consolation for the New Zealand team was that only the first three games in the ODI series - the home side won two - counted for the new ICC Championship.
''If you'd given me a choice at the start of the series between taking out the ICC Championship games 2 1, or winning the overall [ODI] series without those four Championship points, I would have gone for the points, no question,'' White Ferns captain Suzie Bates said.
''They are what really count for us at the moment as we look towards the next Women's Cricket World Cup and our world ranking.''
On a scorching Canterbury day that pushed the mercury up to 29degC, the Ferns were sent in to bat after Bates lost a seventh toss in eight games.
Although England made key early breakthroughs - Bates, Rachel Priest and Amy Satterthwaite were all back in the pavilion cheaply - Sophie Devine (58) again calmly set about underpinning the New Zealand recovery.
Her composure set it up for Katie Perkins to raise the scoring rate through the last seven overs with a career best unbeaten 70 off 88 balls, helping the White Ferns to 230 for eight after their 50 overs.
In reply, England made a poor start. New Zealand pace bowler Lea Tahuhu trapped opening batsman Heather Knight for a duck before Devine chimed in by removing dangerous England captain Charlotte Edwards.
But Sarah Taylor continued her strong form for England, falling just seven runs short of what would have been a stylish century when she was run out by a quick throw to the keeper from Satterthwaite.
Natalie Sciver (65 not out off 63 balls) applied the finishing touches with five overs to spare.
Sara McGlashan played her 126th ODI for the White Ferns, breaking Nicola Browne's record.
