Where the species comes from

World region
New Caledonia
Countries
Grande Terre and the offshore islands
Habitat
Humid forests, tree hollows high up

The app does not yet hold an origin entry for this species. The distribution given here comes from the specialist literature.

The natural habitat is the yardstick for how you furnish an enclosure. Knowing where an animal comes from is knowing why it needs heat zones, hides and a particular humidity.

Husbandry at a glance

The same details appear in the animal’s profile inside the app.

Enclosure
Tall and sturdy, with strong branches. The Animal Welfare Ordinance sets no minimum size for New Caledonian giant geckos. The reference is the German 1997 expert report on reptile keeping: for a pair at least 6 × 6 × 8 snout-vent lengths, i.e. 132 × 132 × 176 cm at 22 cm.
Temperature
22–27 °C, 19–21 °C at night. Above 30 °C it becomes critical.
Humidity
60–75 %, mist in the evening, let it dry during the day.
Lighting
Weak UV-B is beneficial.
Substrate
Coco humus with leaf litter.
Furnishings
Thick vertical cork tubes as a daytime retreat, sturdy branches. The animals are heavy and need load-bearing structure.
Water
A dish and droplets on leaves.
Feeding
Ready-made fruit gecko diet twice a week, plus insects and rarely a small mouse.
Behaviour
Nocturnal, calm, site-faithful. Makes growling sounds.
Handling
Possible, but the bite is strong. Proceed calmly and slowly.
Cohabitation
Alone. Pairs only in a very large enclosure and under constant observation; conflicts end bloodily.
Health
Very long-lived and robust, sensitive to heat.
Seasonal cycle
A cooler phase in winter at 19–20 °C.
Safety
No permit required.

Legal position in Switzerland

No permit foreseen

No permit required. The species does not belong to any of the groups listed in Art. 89 of the Swiss Animal Welfare Ordinance

No certificate of competence foreseen

No proof of competence required. It is only demanded for the animals named in Art. 89 of the Ordinance

No CITES listing

Not listed in the CITES appendices: Import and transfer require no species-protection papers. Keep the proof of purchase nonetheless

Minimum enclosure dimensions

Annex 2, table 5 of the Animal Welfare Ordinance does not list this species. Among snakes the table names only giant snakes (pythons and boas), elapids, vipers and pit vipers, and a few venomous or dangerous colubrids; for the rest no figure appears there.

The general rule in Annex 2 (letter K) then applies: the enclosure must be large enough for everything the species needs (hides, basking spot, climbing branches) to be arranged sensibly. As a yardstick, the ordinance points to expert opinions on a scientific basis. There is therefore no binding figure. The guide values in the calculator come from the 1997 expert report. Binding information comes from the cantonal veterinary office.

Calculate the minimum size

What the enclosure must provide

Provide species-appropriate heat and light zones, UV-B where needed, suitable substrate, retreats, climbing or digging options, water and natural rest periods.

Paperwork

Keep the purchase contract and proof of origin. Use the scientific name to check CITES and import status reliably.

These details are a guide, not legal advice. Binding information comes from the cantonal veterinary office; the text of the ordinance is what counts. More on the legal position
