In 1936 the First Labour Government of New Zealand set up a committee, led by D.G. McMillan, to inquire about the incidence of septic abortion in New Zealand. The report estimated that at least 13 in every 100 pregnancies ended in criminal abortion, that number having increased over the five years prior. In the same time period, while maternal deaths had dropped, the number of deaths due to septic abortions had increased, accounting for two-fifths of total maternal mortality. Based on evidence heard before the committee, it was found that a major reason for abortions was a change in social outlook, "particularly towards the rearing of large families" and "an attitude of pitying superiority towards the woman with many children." Other reasons included lack of suitable housing in cities, lack of help for women in performing domestic labour, and the widespread use of ineffective methods of contraception.
