The Mulloy restoration projects at Ahu Akivi, the ceremonial village of Orongo, Vinapu, Ahu Ko Te Riku, Ahu Vai Ure and the rest of the ceremonial center at Tahai now constitute an integral part of the Rapa Nui National Park, designated by UNESCO as a World Heritage site.
Mulloy's personal library forms the core of a research collection now located on Rapa Nui at the Father Sebastian Englert Anthropological Museum.
