NZC introduced women's Domestic contracts for the first time last year under its ground-breaking Women's Master Agreement.
Nine Central Hinds players have been provided with financial support at CDCA level to compensate them for time spent preparing and playing the one-day Hallyburton Johnstone Shield and Super Smash (T20) competitions.
"Along with our four NZC-contracted players, a total of 13 Central Hinds now sit in the contracted environment, and it makes for a strong and consistent group who will challenge each other to keep growing the Hinds' performances in both formats," said Watkins.
Stars Hannah Rowe, Natalie Dodd and Rosemary Mair are all on White Ferns contracts, while big hitter and 2019/20 Player of the Year Jess Watkin is also contracted by NZC on a Development contract.
Manawatū-raised Kumar could well be the sport's first contracted player to have been born in Fiji.
She turned heads on her Dream11 Super Smash debut last season with two classy running catches — belying any nerves after having dashed up from Palmerston North to New Plymouth that morning to join the squad for the first time as an injury replacement.
The Central Hinds begin their 2020/21 Hallyburton Johnstone Shield campaign on the weekend of November 21-22, when they will host rivals the Auckland Hearts in back-to-back Hallyburton Johnstone Shield one-dayers at Pukekura Park.
The team will also feature in doubleheaders with the Central Stags at every Super Smash game this summer, including home games at McLean Park in Napier from December 27 and Pukekura Park in New Plymouth from December 30.
Admission to all Central Hinds Hallyburton Johnstone Shield matches is free to the public.
