My strong suspicion is that this widespread displacement has to do with the pre-2008 TIGER data for Hawaii being in a different datum than NAD83, which is what was used for CONUS. I'm not sure there's much that can be done except a reimport (preferably from 2008 TIGER, which is NAD83) to ensure better positional accuracy... The same issue may also affect the Northern Mariana Islands, Guam, and American Samoa which were also non-NAD83 before 2008.
