Sophie Devine hits one of her world record nine sixes en route to 93 from 41 balls.

Sophie Devine has smashed 93 off just 41 balls to lead the White Ferns to an easy win over Pakistan at the Women's Cricket World Cup in the UK on Sunday morning (NZT).

New Zealand was chasing 145 for victory in Somerset after 20-year-old Hannah Rowe's three-wicket haul helped bowl a slow-scoring Pakistan out inside 47 overs.

Sana Mir provided the only real resistance among the Pakistani batters, bringing up a half-century only to fall immediately.

GETTY Sophie Devine is congratulated by team mate Katey Martin as she walks off.

Devine's swashbuckling knock, which included a women's ODI world record nine sixes, made sure the White Ferns reeled it in after just 15 overs.

STU FORSTER/GETTY IMAGES Hannah Rowe took three wickets to win player of the match in her first game at the Women's Cricket World Cup.

Opener Amy Satterthwaite also chipped in to post an unbeaten 38.

"It's pretty good to watch a player like Sophie Devine," Suzie Bates said. "We did very well to keep them under 150.

"When her and Priest get going, there's few better boundary hitters in the world. We give someone a crack and they perform.

STU FORSTER/GETTY IMAGES New Zealand wicketkeeper Rachel Priest celebrates as Pakistan's Nahida Khan is bowled by Amelia Kerr.

"Our fielding was a bit sloppy to begin with. If we can tighten things up, we will be more difficult to beat."

Earlier, seamer Hannah Rowe had starred with the ball, taking 3-22 as Pakistan were bowled out for 144.

New Zealand's next match is against hosts England at Derby on Wednesday.

In Saturday's other match, South Africa beat India by 115 runs.

Proteas opener Lizelle Lee hit seven sixes in her 65-ball 92 to lay the platform for a total of 273-9.

India were never in the hunt and slumped to 158 all out - Dane van Niekerk taking 4-22.

The result means England drop out of the top four - the qualifying spots for the semi-finals - before Sunday's clash with Australia.
