Maori here, two things to to put into the arguement.
1, Maori language does not directly translate word to word. One of my kids name translated directly to English is "destroyer of houses", however the meaning behind it is a guardian and protector. Kura urupare may translate directly as gift inside head, but there is likely deeper meaning - im unfortunately not fully vursed in the meaning of this one.
2, the Maori language is dying - if people want to use a word that works for them, provides understanding and expression or brings it into common use then go hard. Use it as much as you can, fuck the purists.
