Surveys of maternal mortality rates in rural areas of Papua New Guinea over the past thirty years report 2-18 deaths per 1000 live births. The national maternal mortality register commenced in 1970 and reports rates of 2-7/1000 deaths for urban areas and 7-20/1000 deaths for rural areas. However, less than a quarter of maternal deaths are believed to be reported to the register: most of the unreported deaths are unsupervised confinements. Nevertheless obstetrical causes now account for 20% of total admissions to hospital and health centres in Papua New Guinea, and are the commonest causes of admission. The great majority of obstetrical admissions come from urban and periurban areas. Most rural women continue to confine at home where only a small fraction of maternal deaths are reported. It is as yet unclear whether modern health services have made any impact on rural maternal mortality rates. A plea is made for more complete reporting of maternal deaths to the national register of both supervised and unsupervised confinements.
