Public access to the Whanganui Regional Museum will be restricted from early September as it undergoes refurbishment.
"The upcoming Whakahoutanga project is designed to rejuvenate the museum's buildings and their contents with a combination of earthquake strengthening, reconstruction, and refurbishment," director Frank Stark said.
The work will be carried out by the Whanganui District Council and will take up to 18 months to complete.
"While it is underway, main museum programmes will continue in a variety of venues, including the David Theatre and Education Room, but others will have to be suspended to allow the work to be carried out safely," Mr Stark said.
Because of this, public access to the Queens Park buildings will be restricted from September 5. From September 19, the museum office, shop, and visitor gallery will be shifted to the former post office building at 62 Ridgway St.
