Four more!
Really wide from Sophie Devine, and Tammy Beaumont shuffles across and drives over the top for four more. She's up to 95.
This is now England's highest T20 score against New Zealand.

The nervous nineties. She's not got long to get that T20 hundred. She'll be thinking about it.
Slow, and wide, from Sophie Devine and Tammy Beaumont carves it over the covers for another boundary.
She's up to 91.
New Zealand skipper Sophie Devine is going to bowl the penultimate over.
Andy Zaltzman
Cricket statistician on BBC Two
Two sixes and 20 fours for England so far. They are heading towards their highest score for England against New Zealand, which is 172.
Tammy Beaumont works a single, before Sophia Dunkley plays out two dot balls to end the over. She's made a run-a-ball 13 so far.
Debutant Emma Lamb is doing some nervous lunges on the sidelines. She's got a smile on her face, though.
Three singles start Hayley Jensen's third over.
Tammy Beaumont is up to 83 - her second highest score in T20 international cricket.

New Zealand look a little bit rusty tonight.
Tammy Beaumont has been brillant today.
Here are the best shots from her half-century...
Alison Mitchell
Commentator on BBC Two
Oh goodness me. That is the second put-down by the captain tonight. I'm not quite sure how she managed to not hold on.
Oh, no. Sophie Devine has dropped another one.
Sophia Dunkley looks to throw the kitchen sink at a flighted, wide one from Amy Satterthwaite, and Devine gets there, has the ball in her hands, but it then pops out.
That isn't great.
Leigh Kasperek's figures of 1-54 are the most expensive by a New Zealand bowler in international women's Twenty20 cricket.
Ouch.
Tymal Mills
England pace bowler on BBC Two
Add it to the highlights reel. This has been an absolute world-class innings.
Alison Mitchell
Commentator on BBC Two
The first six for Beaumont in this innings. A tremendous strike.
Shot! Tammy Beaumont advances down the track and slots Leigh Kasperek over mid-wicket for her first six of the night. She's up to 80.
That's the end of Leigh Kasperek too. She's had a night to forget, conceding 54 from her four overs. England have really targeted her.
Sophia Dunkley twice picks up a couple with a little paddle sweep. I'm surprised it took New Zealand two showings to plug that gap.
Tymal Mills
England pace bowler on BBC Two
She'll be eyeing a hundred at this rate and there's no reason why she can't get there.
Oh! Beauty!
Tammy Beaumont is beaten on her outside edge, as she looks to drive away.
Isa Guha
Former England bowler on BBC Two
Tammy Beaumont has been so good in that cover region today.
