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.

In New Zealand, the crude birth rate in 1850 was 37 live births per thousand people, meaning that 3.7 percent of the population had been born in that year. This rate fluctuates over the next thirty years, reaching it's highest recorded number in 1870 (42.3 births per thousand), before dropping consistently from 1880 until 1935. In 1935, New Zealand's crude birth rate was just 17.4 births per thousand people, however New Zealand then experienced a relatively large baby boom after the Second World War, and did not fall to it's pre-war level again until the late 1970s. From the 1980s onwards, New Zealand's crude birth rate has remained around the mid-teens, although it is expected to fall to a record-low of 12.6 births per thousand in 2020.

With an average of *** births per woman, Afghanistan had the highest fertility rate throughout the Asia-Pacific region in 2024. Pakistan and Papua New Guinea followed with the second and third-highest fertility rates, respectively. In contrast, South Korea and Hong Kong had the lowest fertility rates across the region. Contraception usage Fertility rates among women in the Asia-Pacific region have fallen throughout recent years. A likely reason is an increase in contraception use. However, contraception usage varies greatly throughout the Asia-Pacific region. Although contraception prevalence is set to increase across South Asia by 2030, women in both East Asia and Southeast Asia had higher contraception usage compared to South Asia in 2019. Women in APAC With the rise of feminism and the advancement of human rights, attitudes towards the role of women have changed in the Asia-Pacific region. Achieving gender equality has become a vital necessity for both men and women throughout the region. Alongside changes in traditional gender roles, women in certain Asia-Pacific countries, such as New Zealand, have become more inclined to marry later in life. Furthermore, the focus for younger women appears to be with having stability in their lives and securing an enjoyable job. This was displayed when female high school students in Japan were questioned about their future life aspirations.
