The following table is updated annually:
Cohort fertility
Completed fertility rate for cohorts of women born 1894–1976.
The following tables are updated every five years:
Age-specific fertility rates for the major ethnic groups
Fertility rates by single year of age for Māori, Pacific, Asian and European populations, 2001 and 2006.
Regional fertility rates
Fertility rates by five-year age group for regional council areas, 1996, 2001 and 2006.
Following a review of regional fertility rates, Statistics NZ considers that quality data can only be produced for census years. Regional fertility rates will therefore no longer be published for other years.
The following tables remain available but will not be updated:
Median and average age of mother
- Median age of mother, nuptial, ex-nuptial and total confinements, 1962–2009
- Average age of mother, nuptial, ex-nuptial and total confinements, 1962–2009
- Median and average age of first time mothers, nuptial and total live confinements, 1962–2009
