The Maori name of Aranui Library is Te Kete Wānanga o Aranui.
The building designs of Aranui wood carver and sculptor Ralph Stowers adorn the outside walls and glass of the library. Ralph says the designs on the building reflect both his Māori and Pacific Island heritage. The new library received a significant koha from Kohinga Toi, a group of six Māori artists in Christchurch. Each artist made a panel exploring Matariki, the kaupapa of the work.
