In New Zealand, it is the older women who are taking to motherhood, compared to the women 40 years back.

The birth rate in 1961 was 4.3 births per woman, double of last year's rate of 2.1.
Population statistics manager Bridget Hamilton-Seymour said, "Annual fluctuations in births, in part, reflect changes in the size and age of the population, the age at which women have children, and the number of children they have. In turn, the number of births influences the future size of the population."
