AFAIK Hawaiian isn't even on the list of languages browsers support
Safari will use your system languages in order of preference, even if neither the OS nor the browser itself has a user interface in the language. That's why some sites think I'm Canadian when I visit using Safari.

Yup, there is is, spelled 'olelo Hawai'i (I've omitted one macron and simplified the glottal stops), alphabetized between Hrvatski (?!) and Ido (double ?).
But the issue is a bit academic since I'm tolerably sure that much more than 50% of the population of Hawaii are haoles who don't know a word of anything but English. I know someone I could ask.
