Elder (13), a specialist number 7, made her debut in the black jersey in 2015 and was part of the 2017 World Cup winning squad. Kendra Cocksedge (47) and Selica Winiata (36) have been named as co-vice captains.
Black Ferns Head Coach Glenn Moore said Elder was a natural leader who had quickly made an impact on the culture of the squad since her debut in 2015.
“On the field Les is uncompromising, and her knowledge of the game is outstanding. Off the field she has the ability to bring players together and bring out the best in them. She is a clear communicator, setting high standards for herself for others to follow."
Moore has included seven new forwards and three backs. Three of the uncapped players have been named in previous squads but are yet to have their start in the black jersey.
Joanah Ngan-Woo (Wellington), Kilisitina Moata-ana (Otago) and Arihiana Marino-Tauhinu (Counties Manukau) have all been named in the squad previously and haven't had their debut.
The Black Ferns squad is (Test caps in brackets, new caps in bold).

Moore said preparation for the Women's Rugby Super Series 2019 in San Diego was well under way and it was a chance for the new players in particular to impress at international level.
“Everyone has a desire to be selected for the 2021 World Cup but we have a job to do first in the US, and it's an opportunity for these players to show what they are capable of.
“The young talent we've seen at recent camps is very encouraging and it's meant selection has been difficult and some very good players have missed out.”
Congratulations to all 31 #BlackFerns who were capped at Eden Park on Saturday. A very special shout out to Fiao’o Faamausili who also received her 50th cap!
