Ngaluafe, an Auckland and Northland provincial player, made two appearances for the Blues, both off the bench. He debuted in their match against France in 2013, as a second-half replacement for Jamison Gibson-Park, then a month later got flown over to Bloemfontein when Piri Weepu pulled out of a match against the Cheetahs.[2]
In 2016, Ngaluafe gained a cap for Tonga against Georgia in Suva.[3]
