Almost two-thirds of abortions were the woman's first, and most (59 per cent) were within the first 10 weeks of pregnancy.
The proportion of abortions from women who already had children was rising, up from 50 per cent in 2007 to 57 per cent in 2017.
The total number of abortions performed in hospitals and licensed clinics was 13,285 in the year to June 2017, well down from a peak of 18,511 in 2003.

Prime Minister Jacinda Ardern, whose party campaigned on reforming abortion laws, wants it to be treated as a health issue and removed from the Crimes Act.
