Architecture + was the architectural firm that designed Pātaka. They transformed a 1970s office building that already housed the Porirua City Library,
Whitireia's performance space and Page 90 gallery. Pātaka has galleries with changing exhibitions. The Bottle Creek Gallery is for community and local artists. Other galleries are the Front Gallery, West Gallery, the Maude & Miller Gallery and the Daylight Gallery. The Daylight Gallery has a semi-permanent exhibition about
Ngāti Toa Rangatira, the local Māori
iwi (nation or tribe) called
Whiti Te Rā! Pātaka Art + Museum has an atrium the full length of the building that also connects the Porirua Library, reception, shop, cafē, performing arts studio, and meeting and events rooms and an outside courtyard with a Japanese garden. ==Awards==
