Hoya pulleana is only known from two localities in the southern part of Indonesia’s Papua province, near Sungai Unir and at Kelurahan Iwaka, Iwaka, Mimika Regency. The label on the type specimens only mentions the habitat as ‘forest’. The plant observed at Kelurahan Iwaka was found in lowland riverine forest (Imran pers. comm. to authors Rodda and Simonsson).
