TAOTA co-director Dr Cherryl Smith said the funding gave her organisation the confidence to keep building its capability.
It currently has just five staff. Business manager Adrian Rurawhe has left to campaign for election as a Labour MP, leaving his role to Miriama Cribb. But there will soon be more people in the building.
The upstairs of the large new office in Wanganui's St Hill St has been converted into living space for indigenous scholars from overseas. The first two are due later this year, and more could follow. TAOTA has relationships with universities in Canada, the United States and Australia.
The building is landbanked for Treaty of Waitangi settlement, and TAOTA's landlord is Tupoho Investments.
TAOTA is researching intergenerational trauma, in a big project called He Kokonga Whare that has been divided into four parts. Two of those are contracted out, one to Ngai Tahu and the other to Waikato. The project still has three years to run. It has a new project on asthma starting this year, and will be working with Wanganui schools and Otago University's School of Medicine.
At least 70 people came to the opening of the building, Dr Smith said. She and co-director Paul Reynolds spoke about their current work, and Te Whare Wananga o Awanuiarangi CEO Graham Smith spoke as well.
