Dennis, Have you talked to Hawai'i county about the requirements?
From what I was told depth required depends on the existance of soil or type of rock being built upon. There is no frost in Puna so there's no problem with heave as there is on most of the mainland. If you're building on solid pahoehoe, you should have no problem with surface piers.
Building on soil, depth required as well as the base bearing surface of the pier will have a lot to do with number of piers and type of house being built.
A talk with an engineer or planner who knows about Hawaii's soil mechanics would be helpful.
