Haw. Rev. Stat. § 514B-89
If a sales contract for a unit is signed before the completion of construction or, in the case of a conversion, the completion of any repairs required to comply with section 514B-5, the sales contract shall contain an agreement of the developer that the completion of construction shall occur on or before the completion deadline, and the completion deadline shall be referenced in the developer's public report. The completion deadline may be a specific date, or the expiration of a period of time after the sales contract becomes binding, and may include a right of the developer to extend the completion deadline for force majeure as defined in the sales contract. The sales contract shall provide that the purchaser may cancel the sales contract at any time after the specified completion deadline, if completion of construction does not occur on or before the completion deadline, as the same may have been extended. The sales contract may provide additional remedies to the purchaser if the actual completion of construction does not occur on or before the completion deadline as set forth in the contract.
