Maia Bouchier defied injury to hit 91 as England Women outpowered New Zealand to win the fourth T20 international in Wellington by 47 runs and clinch the series.

Bouchier’s 91 off 56 balls, her second successive half-century, helped England to 177 for three, Charlie Dean taking four wickets as New Zealand were restricted to 130 for seven.

England lost Danni Wyatt, back in the side after playing in the Women’s IPL, early but Alice Capsey and Bouchier – hampered by a quad injury – added 75 in 10 overs.

Captain Heather Knight (21 not out) and Nat Sciver-Brunt (29 not out) smashed 35 off the final 14 balls to set the hosts a daunting target.

That target was made more daunting without captain Suzie Bates, injured in the field, and England struck at regular intervals.

Dean grabbed four for 26, and Brooke Holliday was at the top scoring, with 25 for the hosts.

The win gives England an unassailable 3-1 lead in the five-match series, which concludes in Wellington on Friday.
