[1][2] The type specimen was wrongly labelled as coming from the Nicobar Islands, so the species was named Anisoura nicobarica.

Because the Northland tusked wētā hides in hollow branches and trunks of manuka it is often found associated with firewood.

Northland tusked wētā are nocturnal and during the day they hide in tree holes and cover the entrance, making them hard to find.

[12][8] Anisoura nicobarica lives in tree holes (galleries), while the other two species of tusked wētā are ground burrowers, and all three face outward while occupying the retreat.

[14][9] They also mix their saliva with wood scrapings to seal the entrance of their gallery making the aperture almost invisible which is especially important during their moult.

[9] A captive A. nicobarica has been recorded creating a burrow in soil and roofing it with debris which suggests they can be flexible over their selection of refuges.
