The Black Ferns also announced their contracted squad for 2020, with Saphire Abraham, Kelsie Wills, Chelsea Bremner, Patricia Maliepo and Langi Veainu named for the first time, while Hazel Tubic returns after a stint playing in Japan.
"Every year the standard of rugby, not just here but around the world, is growing and we need to be ahead of the game," said Black Ferns head coach Glenn Moore.
"In the past couple of years we've widened our player pool, introduced new athletes to the Black Ferns environment, and given them test match exposure. In 2021, we will be able to draw on a stronger, experienced and match-fit group of players.
"This is a crunch year for us. We need constant high-level competition to ensure the team is in top form for next year. An eight-test match schedule, more regular training camps, and the added bonus of playing in front of family and friends is massive."
