"Welcome to Maui!” (5)
I believe the answer is:
aloha
'welcome to maui' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for aloha that I've seen before include "Hello from Honolulu?" , "A Polynesian hello or goodbye" , "Hawaiian greeting" , "16 across in Hawaii" , "Hawaiian hello or goodbye" .)
