Parts of Burwood hospital in Christchurch have been closed after engineers found them to be earthquake-prone.
Hospital kitchens and cafeteria and a gymnasium owned by Parafed Canterbury will not reopen until earthquake strengthening work is done, Canterbury District Health Board corporate services general manager Murray Dickson says.
Closures are a disruption but safety is paramount, says Mr Dickson.
Meals were provided by the hospital's catering company, which delivered food, and this will continue until other temporary catering arrangements are made.
Engineers are still assessing the buildings and it is not known when they will be reopened.
