Staff, patients and visitors are unable to drink the water at a Christchurch hospital after it was found to be contaminated with E coli.
In an email to Princess Margaret Hospital staff on Sunday, the Canterbury District Health Board (CDHB) said people should avoid drinking the water until further notice.
“Everyone on the site should use bottled water where possible and do not use zips or plumbed in water coolers until further notice,” the email said.
CDHB chief of psychiatry Dr Peri Renison said on Monday evening the water supply had since tested negative for contaminants and no-one had been harmed.
