First always make sure you know the meaning of the tattoo is that you are getting. Nothing like having a tattoo done especially an Hawaiian one and you do not know the meaning.
Second make sure you have someone do the tattoo that does about the culture of Hawaiian Tribal tattoos. many times you may want to change a part of the design and if you do you could end up offending the culture by even a subtle change.

Third get a tattoo artist that you can trust and make sure they know the culture as well. Do not get something you do not want. If you do get an Hawaiian tattoo you will be in a growing list of people who value these tattoos for their beauty and what they stand for.
