The squad also includes the return of pace-bowler Rosemary Mair, who had been sidelined with a back injury.
Wellington Blaze off-spinner Leigh Kasperek, set to participate in her fourth T20 World Cup, will bolster the spin attack.
The only member of the squad without any T20 World Cup experience is wicket-keeper batter Izzy Gaze.
White Ferns head coach Ben Sawyer highlighted the advantage of Devine and Bates’ extensive tournament experience.
“Congratulations to all of the players named in this squad, it’s a significant achievement to be selected to represent your country at a World Cup,” said Sawyer.
“I’m really pleased with this squad, I think these are our best 15 players to adapt to what will likely be varied conditions.”
The team will be competing in Group A alongside Australia, India, Pakistan, and Sri Lanka.
Prior to their first group match against India on October 4, they will play two warm-up matches against South Africa and England.
The squad is scheduled to depart on September 16 for three T20Is against Australia as part of their preparation for the tournament.
Sawyer will be supported by regular batting coach Dean Brownlie, assistant coach Craig McMillan, and NZC high performance talent and pathways coach Paul Wiseman, who will focus on spin bowling.
