Fifth international at The Spitfire Ground in Canterbury: England 347-5 (50 runs) Beaumont 102; Jones 60; Rowe 2-65 New Zealand 140 (35.2 overs: Halliday 27; Knight 3-24, Cross 344 England won series 4-1 Scorecard
Tammy Beaumont's century secured a crushing win for England at Canterbury by 203 runs over New Zealand, completing a 4-1 international series victory.
Beaumont's score of 102 was the foundation for England's 347-5 run from their 50 overs, their highest ODI score against New Zealand.
Amy Jones was able to make a great 60, while Danni Wyatt's unbeaten score of 43 from 20 balls propelled England past the tourists.
Kate Cross completed a fantastic summer with the ball by taking 3-44. The White Ferns fell to 90-6 because they couldn't chase the rate.
Heather Knight, Skipper, contributed 3-22 to New Zealand's defeat to bowl out for 144. With 14.4 overs remaining, Knight was the last man standing.
England won the 4-1 victory, meaning they have won all their limited-overs series during a busy summer at home.
Beaumont's stellar innings helped them get off to a flying start, and Jones' 93-run partnership put more pressure on a New Zealand team already in ruins.
The White Ferns lost eight fish and appeared exhausted after a long, hard schedule.
The series win and this result will give England confidence as they travel to Australia in January for the Women's Ashes.
Beaumont shines at the summer's end
Beaumont has only three players who have scored more ODI centuries: Meg Lanning from Australia, Suzie Bates of New Zealand and Charlotte Edwards, former England captain.
England had the opportunity to put together their best batting innings in the series thanks to her innings. They displayed a level of freedom and power that was impossible to achieve due to previous batting collapses.
Beaumont was able to score 50 runs from just 55 balls. She also managed seven fours thanks to a New Zealand bowling team that was lacking variety. Beaumont was precise in her timing and she was quick through the mid-wicket, which took her to her half century.
Jones was Jones' ideal foil. Beaumont's positive attitude helped Beaumont succeed despite his struggles with the bat. England's dominance was underlined by Hannah Rowe's four fours in four balls, who is New Zealand's best-known bowler.
Beaumont fell shortly after reaching her century. She was caught by Bates on a Rowe slower ball. However, her innings helped Wyatt, Sophia Dunkley and others to accelerate.
England scored 96 runs in the final 10 overs. Wyatt hit four sixes and three fours as England raced towards their sixth highest ODI total and the highest New Zealand has ever conceded. For a batting lineup that was admittedly tired, this was the game that finally worked.
Still, there are concerns. Lauren Winfield-Hill, the opener Lauren Winfield Hill has not reached an international half-century in 2016 and has a tendency of playing brilliantly but then falling cheaply. In her 43 innings, she was dropped four more times. These chances will be taken by better sides.
Cross highlights England's World Cup pedigree
This is the kind of performance England wants to repeat against Australia in the Women's Ashes on 27 January and then in March when they defend their World Cup title.
All those who had to score runs at Canterbury, in particular Jones and Nat Sciver (who made 39), did. England didn't disappear despite Knight, who is often the anchor falling for a duck. Beaumont was the leader of the charge and Wyatt had the ideal setup for her explosive hitting in final overs.
England has seen spinner Charlie Dean emerge, which was a positive in many ways, especially the way she played at Worcester. Meanwhile, seamer Cross completed an outstanding campaogn with three wickets.
Cross wasn't certain of a start in the 50-over lineup at the beginning of the summer. However, she finishes the series with eight wickets at an economy rate 4.80.
She bowled with speed and accuracy to become England's first-change bowler. This was in support of Anya Shrubsole (injured) and Katherine Brunt (injured).
Sophie Ecclestone, who has had to deal with a sore shoulder from bowling an inordinate amount of overs this summer, took 2-31 and Shrubsole, 1-20.
New Zealand has more testing ahead of them, so the White Ferns will be faced with some tough decisions before they begin their World Cup on their home turf. This was a perfect way for England to close a transformative summer for women's cricket.
"We've had so much people stepping up" - what they said
Heather Knight, England captain: "I wasn't at all at my best at the beginning of the summer against India. I felt a little scratchy. I was really dedicated and worked hard. I am so happy that it all went smoothly, especially considering the harsh winter ahead.
"I enjoyed the series, it was enjoyable and I felt good. I wanted to make match-winning contributions. We've seen so many people step up and put in performances throughout the series.
Alex Hartley, England World Cup-winning spinner, on BBC Test Match Special: "What's exciting about this England team? There's so many opportunities for improvement. Although they are dominant today, they have not been in all series. They have been great at bowling, but they have also had batting falls and will know how to improve.
"But that performance is exactly what they should play, and it will give them confidence knowing that they can play like this, especially with such an important winter ahead."
Kate Cross, England seamer, on Sky Sports: "I felt great all summer to be truthful, I felt confident, and that is because I had a clear role in our team. Those middle overs were boring, and I was bowling stump-to–stump and picking off wickets.
"For me, the most important thing is being part of this group. It's happened at times when I was not sure I would get my England shirt back, so it's really nice to reach milestones.
New Zealand captain Sophie Devine says: "It is one of those games that you just flush down your dunnie. England dominated the game, and we were unable to match their performance.
"We won't dwell on it, there have been some highlights on this tour and that's what will be our reflection."
