5:22pm Right then, that's all from this series and from us! At least for tonight. England return to action against India on Thursday while New Zealand have a couple of warm-up matches before their World Cup campaign begins on June 13.
5:17pm Now to the captains. Charlie Dean has held her own perfectly while Nat Sciver-Brunt has been recovering from her calf injury.
"We learned from that Canterbury game," says Dean, when England had New Zealand 11 for 4 but allowed them to post a match-winning 170 for 5. "When we're on top, we are really trying to be ruthless, and we were today."
Meanwhile, Melie Kerr laments a poor end to this series from her charges: "It's a disappointing finish to the series. Throughout the series we've played some really good cricket but today was really disappointing. I guess it's better to do it now than at the World Cup.
"Losing wickets early, and losing wickets in clump - you want to set the tone and get off to a good start but we haven't been able to. We bat deep but we haven't given ourselves a chance."
5:14pm Player of the match is Dani Gibson with 3 for 14 from her four overs: "There's been a bit of a time out of the game, but to be back and making an impact is great. To get it done with the ball today feels really good, I was just happy to be out there."
Player of the series is Linsey Smith, with 6 wickets at 8.33: "Throughout the series it's being really clinical in that powerplay. Try not to leave the stumps.
"Early on, it's about getting a bit of shape, not too much turn. Throughout the back end, they're looking for a few more boundaries so it's about not being predictable."
5:02pm A truly abject display from New Zealand in this decider, skittled for 80 that was picked off with ease. Kemp, again, sees it out as she did in the first T20I. England have now won the last seven bilateral T20I series against New Zealand
