Transparency International PNG says some Papua New Guineans have to walk four days for medical help when 20 years ago nobody was expected to walk more than four hours.
The anti corruption watchdog group says the country's standard of health delivery has collapsed since the mid-1980s because of a combination of corruption and bad management within the health service.
The AAP news agency says TI has released a global report focussing on health.
The local PNG TI chairman, Mike Manning, says about fifty per cent of medical aid posts operating at PNG's independence in 1975 are now defunct.
Mr Manning has called on the PNG government to recognise the problem of corruption and bad management within the health service and do something about it.
