Canterbury geckos in the wild have been recorded as having low levels of red mites.
All New Zealand geckos have two main threats which are predation and habitat destruction.
The main predators of the Canterbury gecko include mammalian pests such as mice, rats, weasels, hedgehogs, cats, stoats, ferrets, pigs and possums.
With the evolving suburban areas in Canterbury, the geckos are being pushed out of their natural habitat and with conversion by burning and ploughing, this is threatening geckos that live in rock outcrops.

Introduced mammals represent one of the biggest threats to many of New Zealand's native species, including Woodworthia cf.
brunnea.
Birds and lizards filled the role of land mammals in New Zealand before the arrival of humans, and due to the absence of these predatory mammals, many species are somewhat naïve to the dangers of predators.
Native lizards are predated on by cats, mustelids, possums, hedgehogs and rats (both the European rats and the Polynesian kiore).
Some lizards on the mainland and smaller islands went extinct after the introduction of kiore, and many more after the arrival of the various European predators.
The Department of Conservation has estimated that New Zealand's population of 1.4 million domestic cats kill “at least 18.76 million animals a year, including 1.12 million native birds”.

Three species of New Zealand lizards have been declared extinct since human arrival, and a further eight survive only on outer islands where there are fewer predators.
Nocturnal species such as the Woodworthia are more at threat than the diurnal gecko species, as mammalian predators often hunt at night.
Many lizards occur only in small, separated populations today due to habitat loss and predation.
Almost half of New Zealand's reptile species are listed as threatened or endangered, and it has been declared illegal to handle or keep any native lizard without a permit from DOC.
Geckos do have some defence against predators, as they can release (autotomise) their tails at will.
The tail is used as a distraction; it continues to move and distract the predator while the gecko escapes.
As it takes a few years for the tail to regrow, it is not a method that can be used for every encounter.
Larger reptiles and amphibians predate on smaller species, as will larger invertebrates such as centipedes and spiders.
Birds such as owls, terns, rails and kingfishers will predate on geckos, as will blackbirds and magpies.
Introduced predatory invertebrates such as ants, wasps and mantids have been known to predate some New Zealand lizard species.

Mites are common parasites of all lizard species in New Zealand, in the form of tiny red, orange or creamy white spots around the eyes, ears, armpits hind limbs and cloaca.
Internal parasites include a range of nematodes and diseases such as Salmonella.
Skrjabinodon poicilandri is a native nematode species known to infect only geckos.
They are members of the family Oxyuroidea, and as such are “strictly monoxenous (direct, one-host life cycle) with the egg being the infective stage”.
The geckos are infected when they unintentionally consume the eggs.
The study by Mockett et al.
confirmed that the New Zealand gecko nematodes all belonged to the same genus, Skrjabinodon.
Host phylogeny was found to significantly predict the parasite phylogeny, which indicates that cospeciation may have played a role in the evolution of New Zealand geckos and the associated Skrjabinodon, although it was acknowledged that host-switching to closely related host species would have played an important role.
It was also noted that “not all host–parasite associations supported a congruent host–parasite phylogenetic history”.
