"An error-ridden performance from the Kiwis was comprehensively punished by a Fijian outfit which showed more pace, poise and precision than the lacklustre New Zealanders," they wrote.
Kiwi fans vented on social media.
"Two disappointing matches for New Zealanders in less than a week," one person wrote on Twitter.
But it wasn't all negative, many fans have congratulated the Fiji side.
One Twitter user said the Kiwis could learn a lot from "our pacific opponents from the last two weeks".
Way to go Fiji! 🇫🇯 What heart and pride you played with tonight! A famous victory! @NZRL_Kiwis could learn a lot from our pacific opponents from the last two weeks. They won’t. But they could. #NZLvFIJ#RLWC2017
