Three people have been injured, one critically, after being "overcome by chemicals" at a premises in Christchurch this afternoon.
A Fire and Emergency NZ spokesperson said eight crews were called to a premises on Coleridge St in Sydenham before 4pm.
Crews entered the building and rescued two people who had been "affected by chemicals".
Fire and Emergency said crews were working to "make the scene safe".
"There is currently nothing to say it was a chemical leak," the spokesperson said. "There are no details to how the patients have been overcome by chemicals."

Three people were taken to Christchurch Public Hospital, one in a critical condition and two in moderate condition.
