Raukawa Gecko

Scientific Name: Woodworthia maculatus

Although there have been occasional, unconfirmed, reports of 'green geckos' in forest areas on Tiritiri Matangi, until 2004 there had never been records of any of the native brown geckos that are commonly found on other offshore islands (even in the presence of rodents) and on parts of the mainland.
 
But a
set of strange prints was discovered during regular checking of the DoC tracking tunnels which are set to monitor for rodent incursions on Tiritiri Matangi. These were confirmed to be prints of a New Zealand brown gecko - probably Raukawa gecko or Pacific gecko.
 
A subsequent survey of the area at night found probable sign of geckos living in the crevices of cliffs near the tracking tunnel site. During the day, a brief search of the cliff face and nearby rock outcrop found four brown geckos. Because the geckos were buried deep in rock crevices, their identity could not immediately be confirmed, but they were later identified as the Raukawa gecko Woodworthia maculatus, a native New Zealand gecko which is actually quite rare on the mainland, but reaches huge numbers in places where introduced mammals have been eradicated.

Gecko footprintsThe geckos on Tiritiri Matangi are undoubtedly a remnant of a much larger population that once inhabited the Island and that has survived the turbulent history of farming, frequent annual burning and kiore. Two of the first geckos found were young, indicating a breeding population on the cliffs.

Although they face no threat from introduced predators, we know they can fall victim to morepork. In 2012, the remains of three Raukawa geckos were found close to a morepork nest.

The discovery of Raukawa geckos in 2004 brought the total number of lizard species on the Island to three (copper skink, moko skink, Raukawa gecko), still well short of the estimated 10 species that once lived on Tiritiri Matangi. Since then two more species have been introduced: Duvaucel's gecko and shore skink.
