Almost 10,000 people are now believed to have been affected across three provinces by the 7.8 magnitude quake which struck a fortnight ago off of Makira in the country's south.
An eleven-year-old girl who was crushed when a building collapsed on her remains the only fatality of the quakes.
Multiple aftershocks including a major 6.9 quake on the Saturday after the 7.8 quake have kept people in the affected communities on edge and heavy rainfall has caused several landslides on Makira.
