Northland's Hundertwasser Art Centre project will go ahead after the government pledged another $3 million.
The total government contribution is now at $7m. Ground will be broken later this year.
Economic Development Minister Simon Bridges said centre was one of the core actions of Northland's economic plan, and would pump an estimated $3.5m to $3.7m a year into the regional economy.
"The Northland community has worked hard to get this project off the ground and I'm delighted that the Government has been able to provide funding to get the project across the line," Bridges said.
The $3m in funding announced today will be from a regional culture and heritage fund.
Austrian artist Friedensreich Hundertwasser spent 20 years in the Bay of Islands and became a New Zealand citizen. He died in 2000 and is buried on his beloved property not far from Kawakawa.
