The United Nations is urging Pacific governments to address major urban problems, including housing, sanitation and waste management.
The call follows a six month examination of city planning in the region.
The United Nations Habitat Pacific programme manager, Sarah Mecartney, says
governments are not doing enough to address these problems.
"Despite of the growing rise of informal settlements, also the low income households in particular and middle income households, very little has been done to address the housing shortage throughout the Pacific. But no one seems to be particularily concerned about this."
Sarah Mecartney says the issue is magnified in Marshall Islands and in Kiribati, but it also exists in other centres, including in Papua New Guinea and Solomon Islands.
