The fertility rate of a country is the average number of children that women from that country will have throughout their reproductive years. In 1855, New Zealand's women of childbearing age would go on to have approximately 5.3 children on average during their lifetime. Over the course of the next eighty years, the fertility rate would increase to 5.7 in 1870 (due to the continued arrival of settlers to the islands), before decreasing to 2.4 in 1935. During and after the Second World War, from 1935 until the 1970s, New Zealand experienced its 'Baby Boom', where the fertility rate increased to 4.1 births per woman in 1960, before dropping sharply to two births per woman in 1985, and it has remained between 1.9 and 2.2 since then.

The total fertility rate in New Zealand decreased by 0.1 children per woman (-6.02 percent) compared to the previous year. As a result, the fertility rate in New Zealand saw its lowest number in 2023 with 1.56 children per woman. The total fertility rate is the average number of children that a woman of childbearing age (generally considered 15 to 44 years) is expected to have throughout her reproductive years. Unlike birth rates, which are based on the actual number of live births in a given population, fertility rates are estimates (similar to life expectancy) that apply to a hypothetical woman, as they assume that current patterns in age-specific fertility will remain constant throughout her reproductive years.Find more statistics on other topics about New Zealand with key insights such as infant mortality rate, crude birth rate, and total life expectancy at birth.

Infant mortality rate is the number of infants dying before reaching one year of age, per 1,000 live births in a given year.; ; Estimates developed by the UN Inter-agency Group for Child Mortality Estimation (UNICEF, WHO, World Bank, UN DESA Population Division) at www.childmortality.org.; Weighted average; Given that data on the incidence and prevalence of diseases are frequently unavailable, mortality rates are often used to identify vulnerable populations. Moreover, they are among the indicators most frequently used to compare socioeconomic development across countries. Under-five mortality rates are higher for boys than for girls in countries in which parental gender preferences are insignificant. Under-five mortality captures the effect of gender discrimination better than infant mortality does, as malnutrition and medical interventions have more significant impacts to this age group. Where female under-five mortality is higher, girls are likely to have less access to resources than boys.
