Jillaroos co-captain Kezie Apps left the field late in the Pacific Cup final with a lower back problem while Kiwi Ferns back-rower Annessa Biddle suffered a head knock.
Apps landed heavily on her back in a tackle after making a line break and she was unable to see out the match which the Jillaroos won 40-8.
BIddle, meanwhile, copped an accidental knee as she tried to tackle Ellie Johnston head-on.
She left the field for a HIA in the 60th minute.
The Jillaroos welcomed back star fullback Tamika Upton from a calf injury for the final but were missing hooker Keeley Davis, who injured her shoulder at Eden Park in week three.
Cowboys forward Makenzie Weale has been ruled out of the remainder of the Pacific Championships with a pelvis injury.
Meanwhile, Fetu Samoa lost four players to injury during their 60-0 loss to the Jillaroos in week two of the Pacific Championships.
Already missing Sienna Lofipo (concussion) and Pauline Piliae-Rasabale, the Samoans finished the day with only 13 fit players after Sarina Masaga (jaw), Jetaya Faifua (shoulder), Jaydika Tafua (arm) and Jessica Patea (shoulder) all suffered injuries.
Playmaker Faifua finished the day with her arm in a sling while Masaga copped an accidental knee to the head and has reportedly suffered a broken jaw.
"Jetaya, Sarina and Jess Patea have all gone off to hospital," coach Jamie Soward told media post-match.
