Waipā District Council has evacuated the Te Awamutu Museum and an adjacent staff building following a seismic assessment.
Chief executive Garry Dyet made the evacuation call on Thursday, following a report that shows the building is at 20 per cent of the National Building Standard, with a grade D building rating. In the event of an earthquake, grade D buildings represent a risk to occupants 10-25 times that expected for a new building.
Garry said the seismic risk issues were discovered when the council was considering work to replace the roof and windows.
"The issue was identified then and on the basis of health and safety, I made the call to evacuate the building; I was simply not prepared to put any staff member or any member of the public at risk."
