Middlemore Hospital was apparently aware of leaks and mould in its buildings two years earlier than it has previously said.
A report by surveyors in 2010 found problems with the Scott Building's cladding, advanced rot and other damage caused by leaking, Radio NZ reported this morning.
The Counties Manukau District Health Board has said that it first became aware of weathertightness in some of Middlemore's buildings two years later, in 2012.
Greg Simpson, Middlemore's facilities manager at the time, said that he "quite clearly" recalled reporting the findings in the report to senior management and the board.
He asked for a more comprehensive report and funding for urgent repairs.
