New Zealand women face a one in 3300 chance of dying during pregnancy or childbirth, the fourth worst odds among 34 industrialised countries included in Save the Children's annual State of the World's Mothers report.
New Zealand children fared slightly better than their mothers. At 5.9 child deaths per 1000 live births, New Zealand ranked fifth worst in the industrialised world.
The report ranked 176 countries to show where mothers and children fared best and where they faced the greatest hardships using education, income, political status, maternal health and child mortality as indicators.
The Democratic Republic of the Congo was found to be the toughest place in the world to be a mother and Finland the best. New Zealand ranked 17th overall.
New Zealand Perinatal and Maternal Mortality Review Committee chairwoman Cindy Farquhar disputed the figures, with the committee's own report showing about one in 8000 women died in pregnancy or childbirth.
