"We have continued supply to all Northland DHB hospitals as normal; all external customers have been contacted and advised of the situation," Cheong said.
Two areas of the affected site have since been deemed safe and both areas have their own access and ventilation.
Cheong said while the risk was low, the health and wellbeing of staff and patients was paramount.
"Air quality testing came back as very low risk, but as a good employer we are not prepared to take any risks with our staff. Our priority was to move operations and continue supply to our hospitals."
In addition, Occupational Health Managers met the team, informed them of the risks and encouraged them to see their own doctor if they experience any breathlessness or feel unwell at all.
The current location is a temporary measure and a larger site for the medium term is being considered while the costs of fully clearing the original building is worked out.
