New Zealand pace bowler Rosemary Mair has been ruled out of the upcoming tour of England due to a stress reaction in her left shin.
Mair will be replaced in the 16-player squad by uncapped Auckland quick Molly Penfold for the tour that includes three T20Is and five ODIs.
Mair has taken four wickets in 11 ODIs but has enjoyed more success in T20Is with 13 wickets at 24.69
"It's very unfortunate news for Rosemary who's started to form a key part of our bowling attack in recent times," New Zealand head coach Bob Carter said. "Rosemary is naturally gutted she can't tour but we wish her well with the injury and look forward to having her back on the park soon."
Bowling coach Jacob Oram was looking forward to working with 20-year-old Penfold on what is hoped will be a valuable learning experience.
"Molly has raw, fast bowling talent," he said. "She brings a desire to learn about her game and a willingness to work hard and absorb new information. She will benefit a lot from touring and training day in, day out with our best bowlers in the country."
New Zealand are hosts of next year's ODI World Cup but have only won one of their last one of their last 15 matches in the format.
