Justification of Red List Category
This species likely became Extinct during the 17th century as a result of predation by rats and hunting by human settlers.
None persisted to modern times.
Tribonyx hodgenorum is known from subfossil remains on the North and South Islands of New Zealand. It was apparently widespread, but the youngest specimen material dates from the 17th century, when it likely became extinct.
Remains were found at widely spread locations on both the North and South Islands of New Zealand, indicating that it was presumably common prior to the arrival of the Polynesians and associated commensal animals.
The main reasons for its extinction are likely to have been predation by Polynesian rats, and hunting by human settlers.
