All above species are native to New Zealand, and have become endangered as a result of habitat destruction following human settlement and nest predation by introduced mammals.

They are easy to breed, but as with all protected native species in New Zealand, a licence from the Department of Conservation is required to keep them in captivity.

The orange-fronted parakeet is highly endangered, with less than 200 individuals remaining in the North Canterbury region of the South Island.

Understanding the sex ratios within populations helps in managing breeding programs and maintaining balanced demographics in captivity, contributing to the preservation of this species.

Accurate sex testing plays a pivotal role in effective population management and conservation strategies for Kākāriki.
