Numonohi facilitates the support and coordination of Bible translation, church planting and medical work for New Tribes Mission throughout the Papua New Guinea mainland.
[1] The centre also hosts a store, post office, carpentry and mechanical shops, administration buildings, dorms, both medical and dental centres, a gymnasium as well as outdoor basketball/tennis courts and roughly 45 houses.
Due to many incidents over the years a security fence was erected to protect the missionaries.
Before the eight-foot chain-link fence was built it was not uncommon for neighbouring tribes to assemble on the soccer field and launch their spears and arrows at one another.
Numonohi's elevation is slightly over 5,200 feet and is located at Lapilo south of Goroka, the provincial capital.
