Ashburton Hospital's operating theatre block has been closed due to earthquake concerns.
The Canterbury District Health Board closed the block this morning (Tue) following advice from external structural engineers based on inspections, carried out last week.
Engineers concluded parts of the theatre block were earthquake prone and had very high seismic risk because of their construction being unreinforced masonry.
Canterbury District Health Board Chief Executive David Meates met with theatre staff earlier this morning to tell them about the closure.
"We've had to cancel surgery at short notice - and I apologise to all those who've been affected. I realise how inconvenient this closure is - however, we cannot continue to operate in this theatre given that we are still experiencing quakes and we know parts of the building are earthquake-prone," Mr Meates said.
