“I’m glad we are able to do something that is distinctly Hawaiian,” Kanekuni said. “It’s authentic. It’s who we are.” 

Question, Emily, is Kanekuni of Native Hawaiian descent?  If Kanekuni is not Native Hawaiian, I hope you see the issue associated with him creating artwork that depicts his perspective of Hawaiian culture, then markets it as "authentic."  If he is Native Hawaiian, the labeling of "authenticity" is still problematic as I've never heard of the traditional customary practice of honoring Lono through the displacement of farmlands by urban sprawl.  

The title of this article is "Honolulu Rail Art Celebrates Hawaiian Culture."  In my opinion, a more apt title would probably have been: Honolulu Rail Art Misappropriates Hawaiian Culture.
