Tammy Beaumont made 81 as England cruised to a series-clinching 56-run win over New Zealand in the second one-day international at Seddon Park, Hamilton.
The opener was fluent throughout her 96-ball knock, sharing a 70-run partnership with captain Heather Knight as England laid the foundations for a big total
But New Zealand fought back and, at 6-59, England needed a quick 48 from Amy Jones to get them to a competitive 252 all out.
It proved to be more than enough as the White Ferns quickly fell behind the required total in the face of some disciplined England bowling.
Brooke Halliday and Izzy Gaze gave New Zealand hope with a 100 partnership for the fifth wicket. But England brought in their seamers to halt the momentum.
The duo fell in quick succession and England quickly wrapped up victory as the Kiwis were bowled out for 196 in the 45th over.
Nat Sciver-Brunt was the pick of the England bowlers with figures of 3-21.
With an unassailable 2-0 lead in the series, Knight's side will look to complete the clean sweep in the third ODI at the same venue on Sunday.
