Builders have yet to start work on strengthening Timaru Hospital's Gardens Block.
The work, which is expected to take 28 weeks, was initially to start today, according to an earlier report.
However, tenders for the job only closed yesterday, South Canterbury District Health Board (SCDHB) chief executive Nigel Trainor said.
Staff moved out of the building in July 2012 after an engineer's report warned the northern end of the six-storey building could collapse in a severe earthquake.
The Gardens Block will house the administration offices of the SCDHB and some of the DHB's allied health services.
