Haw. Rev. Stat. § 290-3: Public auction.

If the vehicle is not repossessed within the time limits provided in section 290-2, the vehicle may be disposed of by public auction, through oral tenders, or by sealed bids, after public advertisement has been made once in a newspaper of general circulation; provided that the public auction shall not be held less than five days after the publication has been made. Where no bid is received, the vehicle may be either sold by negotiation, disposed of or sold as junk, or donated to any governmental agency.
