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.
