Her gritty half-century laid the foundation for a competitive total after the Kiwis had wobbled to 38-3.
There was a moment of concern mid- innings when Devine, who manages Type 1 diabetes, had to halt play to check her blood sugar levels. Out came a few sweets and a sugary drink before she was back at the crease.

“I had to take a few jelly beans and coke to get going. It wasn’t the prettiest innings but sometimes you’ve got to do it ugly.”
Her knock of 63 off 85 balls, laced with two fours and two sixes, provided the spine of the innings.
The other New Zealand great Suzie Bates, who had collected consecutive ducks earlier in the tournament, finally found some form with 29 studded with six boundaries before a mix-up saw her run out just when she was looking set.

Bangladesh’s reply never got out of first gear. Their top five batters failed to reach double figures and it took them 15 overs to find their first boundary.
Jess Kerr caused trouble at the top of the order with 3-21 while Lea Tahuhu ensured there was no fightback with 3-22.
Bangladesh folded tamely with leg-spinner Fahima Khatun waging a lone battle. She top-scored with 34 before becoming the last wicket to fall as she skied a delivery from Eden Carson out to extra-cover.
New Zealand sit fifth in the eight-team table, one place outside the semi-final spots, level on points with Bangladesh who are one place below.
The White Ferns now head to Colombo for their games against Sri Lanka and Pakistan before wrapping up their group stage in Bombay with matches against hosts India followed by England in Vizag.
“Our batting is not consistent. The lower order has done a decent job, but the top order needs to shoulder more responsibility,” Bangladesh skipper Nigar Sultana conceded after the defeat.
Her team face South Africa and Australia in Visakhapatnam before taking on Sri Lanka and India in Mumbai.
