The fungus was not as toxic as the black mould found in the building but could still cause skin rashes, eye irritation and "a tickle in the throat", Mr Wynyard said. The clean-up was ahead of schedule with most of the carpet removed from the contaminated ground floor but it could take six months to identify the source of the leaks and replace any walls, ceilings or floors found to be contaminated.
Mr Wynyard said the council had signed a six-month lease on a building on Grey St which would better accommodate some staff and other offices were being sought.
Outside the council building, contractors began installing nets under the glass verandas which were yesterday named a hazard, communications manager Aimee Driscoll said.
"Back in June there was an injury at the Historic Village. As a result there were 100 sites that required safety audits. ...The glazing came back as one of the areas we needed to look at."
Thermal expansion and contraction had lessened the stability of the glass, she said.
There were cracks in 10 panes of the toughened glass so those sheets would be replaced next month. Until then the net would prevent pedestrians being injured by falling glass.
