Whanganui sculptor Angela Tier's Spook exhibition of a colony of small bat urns is to also help raise awareness that the mammal is endangered.
Tier says we may already have lost one native species of these tiny bats.
"The greater short-tailed bat was last sighted in 1965, and has been declared extinct - so we should do what we can to protect our remaining native species."
The pekapeka is our only surviving land mammal and threatened by habitat degradation and disturbance, as well as predation and competition from introduced mammals.
