When Was Hawaii Settled?

[Punatic007]

I wonder if there is an amount of time after a group has migrated to, settled or conquered an area or this island chain for example, that the group of people are legally deemed "native" per the United Nations? Or does it only pertain to people who rose from the earth in that specific area?

I can't even engage in conversations about the "native" Hawaiians because it seems we are all immigrants. And the Hawaiian Kingdom was not solely of Polynesian citizenry, there were caucasians, Asians etc..
