"This is a new era for the Kiwis and that's again reflected in the make-up of this squad as it was for the Denver Test," Maguire said.
"A lot of experienced players have moved on in recent years in the shape of Simon Mannering, Thomas Leuluai, Manu Vatuvei, Jason Nightingale, Ben Matulino, Kieran Foran, Russell Packer and others.
"For us it's really exciting bringing in these new players as we strive to take the national side to the place we want it to be. That starts with the Test against the Kangaroos."
The Kiwi Ferns have also added a number of debutants for their upcoming match against the Jillaroos, which will be played before the Kiwis take on the Kangaroos in October.
Onjeurlina Leiataua, Masuisuimatamaalii Tauasa-Pauaraisa (Warriors) and Lavinia Gould (Broncos) have been included in the squad after impressing during the NRL Women's competition this year.
