Sent the same questions over to HPD, Got what i expected back.
Thank you for your inquiry. The applicable section is Hawaii Revised Statutes Section 134-25, which states:
[§134-25] Place to keep pistol or revolver; penalty. (a) Except as provided in sections 134-5 and 134-9, all firearms shall be confined to the possessor's place of business, residence, or sojourn; provided that it shall be lawful to carry unloaded firearms in an enclosed container from the place of purchase to the purchaser's place of business, residence, or sojourn, or between these places upon change of place of business, residence, or sojourn, or between these places and the following:
(1) A place of repair;
(2) A target range;
(3) A licensed dealer's place of business;
(4) An organized, scheduled firearms show or exhibit;
(5) A place of formal hunter or firearm use training or instruction; or
(6) A police station.
"Enclosed container" means a rigidly constructed receptacle, or a commercially manufactured gun case, or the equivalent thereof that completely encloses the firearm.
(b) Any person violating this section by carrying or possessing a loaded or unloaded pistol or revolver shall be guilty of a class B felony. [L 2006, c 66, pt of §1]
As to the finer details of your question I suggest you seek your own independent legal advice.
Thank you
