Hawaii Revised Statutes Division 1. Government § 386-83

(a) If payments of income and indemnity benefits have been made voluntarily by the employer, the making of a claim within the time prescribed in section 386-82 shall not be required. No such payments shall be deemed to have been made if the payments are in the nature of a gift and not intended as compensation, or are made by welfare or benefit organizations operating under direction or control of the employer, or are for medical, surgical, or hospital services and supplies, or are made as wages during periods of partial or total disability if the employer notifies the director of labor and industrial relations at the time in writing that such payments of wages are not in lieu of and shall not be considered as compensation.

(b) Unless the employer is prejudiced thereby, failure to make a claim within the time prescribed in section 386-82 shall not bar a claim to compensation if objection to such failure is not raised at the first hearing on the claim of which the employer is given reasonable notice and opportunity to be heard.
