This poorly known species is classified as Near Threatened because it is thought to have a moderately small population which is restricted to very low lying forest. These areas are being rapidly converted to oil palm plantations and hence the population is undoubtedly declining.

|Range Description:||Loriculus tener is endemic to New Britain, New Ireland and New Hanover (= Lavongai) in Papua New Guinea. It is, and appears always to have been, a rare species but it is unobtrusive and likely to have been overlooked. The few recent records have been from forest edge, where it is more easily observed (Mayr 1934, Gilliard and LeCroy 1967, K.D. Bishop in litt. 1996, G. Dutson pers. obs. 1997-1998, C. Eastwood in litt. 1999, J. Pilgrim in litt. 1999). |

|Population:||The population is estimated to be in the band 10,000-19,999 mature individuals, equating to 15,000-29,999 individuals in total, rounded here to 15,000-30,000 individuals.|
Trend Justification: Buchanan et al. (2008) calculated the rate of forest loss within the species's range on New Britain as 18.2% over ten years.
