Papua New Guinea's National Disaster Centre says it does not have adequate resources to respond quickly to natural disasters.
The centre has been critised for its slow response in helping tens of thousands of people affected by flooding in PNG's Morobe and Oro provinces and part of the highland provinces..
The director, Martin Mose, says it cannot respond within 24 to 72 hours because a lack of workers and funding.
He called on PNG's 22 provinces and its administrations to hire more people to speed up the disaster response time
"Wwe have not been well resourced both at the national level at the national disaster centre and, of course, at the provincial level," Mr Mose said.
"As well they have not been well resourced in terms of manpower and funding and that definitely affects logistics strengths or capacity of provincial disaster offices."
