The St Helens Hospitals were maternity hospitals located in seven New Zealand cities. They were the first state-run maternity hospitals in the world offering both midwifery services and midwifery training. The first hospital opened in 1905 in Wellington and the last one in Wanganui in 1921. The services of the St Helens Hospitals were gradually incorporated into other hospitals and the last hospital to close was in Auckland in 1990.
