Plans to have a museum on the Waitangi Treaty Grounds by next year have been pushed back.
The $12 million development in Bay of Islands is to include an education centre.
National Waitangi Trust Board chair Pita Paraone said it had secured most of the funds needed, but that had taken longer than expected.
He said the original plan was to have it built by the 175th anniversary of the signing of the Treaty next year, but that had been pushed back to 2016.
Mr Paraone said resource consent had been approved and instead, the first sod would be turned on Waitangi Day next year.
