"We've just had a very competitive Women's Provincial Championship season and we want to continue the momentum."
The squad features 18 current Black Ferns including World Rugby's 2015 Women's Rugby Player of the Year Kendra Cocksedge, and captain Fiao'o Fa'amausili.
The squad includes 14 out of the all-conquering Auckland Storm side, with 38-year-old Emma Jensen needing just one more test to surpass Anna Richards as the most capped Black Fern.
The coaching staff has also been confirmed. The assistant forwards coach is once again Wesley Clarke and Grant Keenan has been appointed as assistant backs coach for the first time. Keenan is currently coach of New Zealand Heartland XV and Mid Canterbury.
He was also the coach of Auckland B from 2011-2012 and coached professionally in Japan for Toyota from 2007 to 2011.
New Zealand Rugby's head of women's rugby development Cate Sexton said the experience within the coaching and management team and depth of player talent was indicative of the increased interest and resources for women's rugby at all levels.
"Naming 56 players from around New Zealand who have a shot at the black jersey shows how much talent is out there. We really want to develop that talent and make sure when we select the squad for our test series and later the Women's Rugby World Cup that we have the best of the best."
