Recent phylogenetic studies have confirmed the unique position of this genus as well as the closeness to the kākā and the kea, both belonging to the New Zealand parrot genus "Nestor". Together, they are now considered a separate superfamily within the parrots, Strigopoidea, the most basal of all living parrots. Within the Strigopoidea, the kakapo is placed in its own family, Strigopidae. The common ancestor of the kakapo and the genus "Nestor"

The kakapo is critically endangered; as of August 2018, the total known adult population was living individuals, all of which are named. Because of the introduction of predators such as cats, rats, ferrets, and stoats during European colonisation, the kakapo was almost wiped out. Conservation efforts began in the 1890s, but they were not very successful until the implementation of the Kakapo Recovery Programme in 1995. Most kakapo are kept on two predator-free islands,
