A ceramic bottle which once contained "Ye Olde English Brewed Ginger Beer" made by the Wanganui Aerated Water Company and a clay doll are two of the backyard finds she has seen.
"Sometimes it is the story rather than the thing itself that is interesting," said the artist.
She will be stationed in the gallery Wednesday and Thursday afternoons from 1.30 – 4.30pm where visitors can meet her, see how the library is growing and bring ceramic objects to add to the collection.
"You can either bring the object along or if it's too fragile to bring, a photograph will suffice," she said.
The objects can include all sorts of things: cups, plates, vases, functional items, figurines and contemporary art.
Fitzharris' work can also be viewed at the Creature exhibition showing at the Sarjeant's objects gallery upstairs from the i-Site at 31 Taupo Quay.
Her residency ends in late June when she will take her library of things with her back to Dunedin and it's from there and the stories she has gathered that a new body of work will grow blurring the lines between fiction and non-fiction.
The exhibition will take place later this year or in early 2019.
