Auckland's War Memorial Museum still doesn't have a re-opening date after closing on Saturday when asbestos dust was found in multiple areas.

The dust isn't air-borne - and has been found in the older part of the museum and Grand Foyer, where the emergency exits are located.

Staff have been working remotely.

Deputy mayor Desley Simpson says the museum's doing the right thing and putting safety first. 

"They're working under a licenced asbestos assessor to actually get rid of it."
