The Deputy Chief Executive of Health New Zealand South Island has expressed “deep concern” after several radiology staff at Christchurch Hospital reported becoming ill, potentially due to exposure to fumes from a nearby construction site.

The fumes are believed to be from Hexamethylene Di-Isocyanate (HDI), a chemical used in painting work close to the hospital.

One staff member has been hospitalised, while others have experienced symptoms such as breathing difficulties, rashes, and headaches.

“All construction activity on the Christchurch Hospital campus is currently paused until we can establish the exact cause. Work will not resume until I am confident we are providing a safe environment for everyone,” said Martin Keogh.

Keogh reassured the public that there have been no reports of patients being affected by the potential exposure based on the information available so far.

“I fully understand the seriousness of the situation and am deeply concerned about the impact on our staff. All affected staff have access to appropriate support, including clinical assessments from a specialist doctor,” Keogh said.

He added that they are investigating whether the issue may have started earlier this year. “As part of the full investigation, we are working to establish exact timelines.”

Keogh said the health and safety of staff and patients is the top priority and that construction will only resume once the working environment is confirmed to be safe.

WorkSafe and relevant unions have been notified of the situation.
