The Rotorua Museum will remain closed pending an engineering report on damage caused by last week's earthquake.
The museum was closed on Friday as a precautionary measure after cracks were noticed in the older part of the heritage building.
Museum director Stewart Brown said damage included new cracks in walls, ceilings, floor slabs, beams and columns.
He said a detailed seismic assessment was under way and a report was due soon.
Mr Brown said after that a decision would be made abut the future of the museum.
In the meantime, its 45 staff are on paid leave.
