Smith said the coaching group were impressed with what they saw from the debutants during Super Rugby Aupiki.
"These players really showed up in Aupiki. They are young, eager and really deserve the chance to have a crack."
Four of the debutants come into the front row: Bay of Plenty's Natalie Delamere and Angel Mulu, Canterbury's Lucy Anderson and Waikato's Tanya Kalounivale. Youngsters Kaipo Olsen-Baker, 19, and Tafito Lafaele, 21, join the selected loose forwards while Olympic gold medalist Ruby Tui is named in the Black Ferns for the first time.
Several experienced players including Les Elder, Eloise Blackwell and Renee Wickliffe have missed selection for the Pacific Four Series. Smith confirmed it was important to make sure all players can put their best foot forward when wearing the black jersey.
"These are players that have had a significant impact on the Black Ferns team for a long time. We want them to be in the best possible condition to be selected for Rugby World Cup."
The Pacific Four Series acts as a qualification pathway for the top tier of WXV, World Rugby's new global competition featuring the top 16 nations in women's rugby.
With Rugby World Cup 2021 (played in 2022) fast approaching, Smith said the Pacific Four Series is also about developing the Black Ferns game.
"We've been looking at videos and doing a lot of education around what type of game we want to play. There is potentially a bit of an experimental tinge to it but we know we have some catching up to do and now is the time to do it."
Joanah Ngan-Woo, Luka Connor and Tanya Kalounivale have all recently left behind their day jobs and signed professional contracts for the remainder of 2022.
