The Bay of Plenty iwi of Ngai Tuhoe will officially open its new headquarters next month and claims it will be the country's first-ever so-called "living" building.
The tribe's $15 million project, Te Wharehou o Tuhoe, has been developed to have virtually no environmental impact.
Te Uru Taumatua chair Tamati Kruger says the opening has been delayed because the complex had to meet strict conditions around environmental standards.
It had aimed to complete construction in December, and then in January.
The tribe is expecting people with an interest in architecture from across the world to be at the 8 March opening.
