Weka populations can persist in highly modified habitats, but they have disappeared from huge areas of their former range, suggesting that they can adapt to a wide range of conditions but are particularly vulnerable to threats.

Drought has been implicated in the disappearance of Weka from some areas.

Weka are important in the bush as seed dispersers, distributing seeds too large for smaller berry-eating birds.

Where the Weka is relatively common, their furtive curiosity leads them to search around houses and camps for food scraps, or anything unfamiliar and transportable.

The breeding season varies, but when food is plentiful, Weka can raise up to four broods throughout the whole year.

On average, female Weka lay three creamy or pinkish eggs blotched with brown and mauve.

Weka are classed as a vulnerable species.

The Department of Conservation's Weka recovery plan, approved in 1999, aims to improve the conservation status of threatened Weka, clarify the status of data deficient Weka, maintain the non-threatened status of other Weka, and eventually restore all Weka to their traditional ranges as a significant component of the ecosystems.
