I've seen similar slugs in the forest, but never in the alpine at 1600m. A v cool critter!
Small cicada. Four year old's hand for scale.
Early flowering tawari. This tree was in an open, sunny and sheltered clearing. More trees nearby that were not so sheltered, had plenty of buds but no open flowers.
Lots of birds seen too; these were the Coprosma-rich poos. C. pseudocuneata was fruiting well on the forest margin and could be the poo-contents (https://inaturalist.nz/observations/20297958)
