Gallery director Penelope Jackson said the year's achievements demonstrated the importance of art in the community, as well as in a wider context.
"We are contributing to the visual arts scene in a major way in New Zealand ... We stick to our knitting, achieving very satisfying results," she said.
"Given our youthfulness as a gallery, it's a pleasure to be able to say you have three top class exhibitions touring, with one going international. Logistically this is huge to organise but very very exciting for us all as this has been a real team effort."
Ms Jackson said it was fantastic to see the gallery become entrenched in the community and the audience grow.
A varied range of exhibitions and events helped to attract different members of the community to the gallery, she said.
Currently on show were Black Rainbow, featuring works by the late Ralph Hotere and the Michael Parekowhai-carved Steinway grand piano.
