When Mauicetus was first named it was originally as Lophocephalus. However this name had already been used to name a genus of beetle. Under international rules governing the naming of animals, the first use has priority, so the fossils of this whale were renamed Mauicetus. Mauicetus lived in the waters around the Pacific during the Oligocene. A former species, M. waitakiensis, has now been re-assigned to Tohoraata, while another species, M. lophocephalus, has been moved to Tokarahia.
