As England set the stage for a large total, the opener scored 70 runs in a partnership with captain Heather Knight while playing with fluidity throughout her 96-ball knock.
However, New Zealand countered, and England needed a fast 48 from Amy Jones to get them up to a competitive 252 all out after they had lost 6-59.
That proved to be more than sufficient, as the White Ferns soon fell behind the needed rate when they were faced with some disciplined England bowling.
With a century partnership for the fifth wicket, Brooke Halliday and Izzy Gaze gave New Zealand optimism, but England countered the momentum by bringing back their seamers.
Following the fast falls of the pair, England quickly secured the victory by bowling the home team out for 196 in the 45th over.
Nat Sciver-Brunt, who took 3-21, was the most impressive bowler for England.
Knight’s team will look to finish the series clean in the third ODI at the same location on Sunday after jumping out to an unstoppable 2-0 lead.
