"It is great to have another major entity alongside central government who has assessed and positively endorsed the project," she said.
"It is the community aspect of the project that is now driving funders like Foundation North to want to help us. Community is a very important word out there and that is what the HAC project is now all about".
The $1.8m is a significant contribution to a project that will provide Whangarei and Northland with two world class art galleries, Ms Whittaker said.
The Wairau Gallery will be the first dedicated and curated contemporary Maori art gallery in New Zealand, and will showcase in particular artists from Te Tai Tokerau.
The Hundertwasser Gallery will contain over 50 original pieces on loan from Vienna and will be only the second place in the world where Hundertwasser's art can be viewed publicly.
