New Zealand Women offspinner Leigh Kasperek has been sidelined for a minimum of eight weeks with a broken finger. X-rays confirmed she sustained an avulsion fracture to her right index finger while training in South Africa last week for the seven-match ODI series which starts on October 8. Kasperek will miss that series as well as New Zealand's home series against Pakistan in November.

Auckland allrounder Maddy Green, who also bowls offspin, will replace Kasperek for the South Africa tour. Green, who last played for New Zealand in July 2015, has played eight ODIs so far but has only one wicket to her name. She is yet to score an international fifty.

"We do feel our bowling stocks are quite well covered," coach Haidee Tiffen said. "Maddy provides cover if we do need it, but we've also already got the experience of [off-spinning allrounder] Amy Satterthwaite who now steps up into that bowling role for us, as well as [legspinners] Sam Curtis and Erin Bermingham up our sleeves. And, of course, the class of Morna Nielsen.

"While it's obviously extremely disappointing for Leigh, and we wish her a swift recovery, she returns to Dunedin safe in the knowledge that the team has had very good preparation here and a really good lead-in."

Kasperek, who made her international debut last year, has been one of the leading bowlers for New Zealand. She was the joint-highest wicket-taker in the World T20 in India earlier this year, with nine scalps from five matches and an economy rate of 4.91.

New Zealand will miss Kasperek for the six ODIs that will count for the ICC Women's Championship to qualify directly for next year's World Cup. Australia, who have already qualified, lead the table (30 points) followed by West Indies (20) and England (19). New Zealand lie fourth on the table with 16 points.
