Once bonded, a kiwi pair is usually monogamous.Kiwi partnerships have been known to last longer than 20 years. Every third day or so the pair comes together to share a burrow, and at night they perform duets, calling to each other.
Divorces also happen, especially in high-kiwi density areas in Northland. Divorces can be caused by breeding failures or if birds are young and early in their breeding career.
Breeding seasonThe main breeding season runs from June to March when food is most plentiful. The exception is brown kiwi in the North Island, which can lay eggs in any month.
In captivity, male kiwi can reach sexual maturity at 18 months, while females can lay their first eggs when they’re about three years old. In the wild, kiwi usually do not breed until much older. Wild females lay their first eggs at 3-5 years of age.
