The group, drawn from clubs that did not make the 2016 NRL playoffs, features eight who have yet to play for the national side – Manly prop Addin Fonua-Blake, Warriors utility David Fusitua, Warriors centre Solomone Kata, Warriors prop Sam Lisone, Sydney forward Isaac Liu, Wests centre Tim Simona, Parramatta centre Brad Takairangi and Warriors second row Bodene Thompson.
Liu, Takairangi and Thompson have been part of Kiwis squads before, without actually taking the field.
The wider squad currently consists of 36 players and will be named in instalments as their teams drop out of NRL premiership contention over coming weeks. The size of that squad will also fluctuate, depending on injuries and other unavailabilities that arise.
Several Kiwis regulars are already ruled out through injury and other factors, including Roger Tuivasa-Sheck, Peta Hiku, Dean Whare, Kieran Foran and Kodi Nikorima.
A final travelling squad of 24 will be named during the week after the NRL Grand Final on October 2.
