Haw. Rev. Stat. § 803-11: Entering house to arrest.

Whenever it is necessary to enter a house to arrest an offender, and entrance is refused, the officer or person making the arrest may force an entrance by breaking doors or other barriers. But before breaking any door, the officer or person shall first demand entrance in a loud voice, and state that the officer or person is the bearer of a warrant of arrest; or if it is in a case in which arrest is lawful without warrant, the officer or person shall substantially state that information in an audible voice.
