The teenage birth rate in the wider Whanganui area has almost halved in the past seven years.
New data from Statistics NZ for the Whanganui/Manawatu region shows there were 200 births by mothers aged 19 or under last year, down from 363 in 2008.
This is a rate of 18.7 births per thousand, and the lowest rate in at least 24 years since records were made available in 1991.
Total birth numbers in the Whanganui district increased to 558 after dropping below 500 for the first time in 25 years in 2014.
Birth rates trended down in the past 20 years, but have flattened out in the past five years.
