The National Disaster Management office in Papua New Guinea says it will today assess the damage a landslide has caused in the Highlands regions.
Heavy rain caused a massive landslide on the weekend and the government has declared a natural disaster zone on the Okuk Highway in Simbu Province.
The slip displaced some 3000 people, wrecking their homes and gardens and is affecting four provinces.
There are reports that businesses have begun controlling their food and fuel distribution as panic buying sweeps the region.
The National Disaster Management Office's acting director, Martin Mose says officials are now assessing the damage.
"We will be travelling up there to have a first time information on the actual situation to come and advise cabinet about the situation and what kind of action it must take immediately."
Martin Mose says people might be in need of temporary food, shelter and other supplies.
