Haw. Code R. § 16-74-327
Boxers may be allowed two hours after the official weigh-in time to make contract weight. However, all fines, forfeitures, etc. may be based upon a boxer's weight at the time specified in his contract, unless otherwise authorized by the commission. Boxers who fail to make the weight agreed upon in their contracts shall be fined ten per cent of their purses with a minimum of $5 and a maximum of $100, and their managers shall be fined a like amount. If a boxer is able to make the weight between weighing-in time and two hours of weighing-in time no forfeit shall be imposed nor shall a fine be assessed. Fines shall be divided fifty per cent to the other boxer and fifty per cent to the commission, or promoter, as determined by the commission.
