Newcomers Matt McKilwrick, Sio Siua Taukeiaho and Isaac Liu have been brought into the Kiwis train-on squad for the end of year tour of England.
The Sydney Roosters trio are among nine players added to the extended group, after their teams were knocked out of the NRL playoffs last week.
Hooker McKilwrick is originally from the Halswell Hornets in Christchurch and transferred to Sydney from the Canberra Raiders this season. With first-string hooker Jake Friend initially sidelined, he began the season as the Roosters starting No9.
Second-rower Taukeiaho played his junior football with Otara Scorpions and spent time with the Warriors, before joining the Roosters and playing a prominent role, mainly off the interchange bench, as they took out the minor premiership.
Lock Liu also hails from Auckland, playing for the Otahuhu Leopards, and has three international caps for Toa Samoa to his credit.
