"The staff member worked a shift on a ward at Wellington Regional Hospital before testing positive – however they did not have symptoms, wore a mask, and followed all of our usual safety precautions."
"A number of other staff from the ward attended the same event and are currently under symptom watch."
CCDHB said they were confident the risk of infection to patients and others on the ward was "very low", and no patients were considered close contacts.
"Our Infection Prevention & Control team has identified patients as casual – not close – contacts," they said.
"We are therefore monitoring patients for symptoms and will test relevant patients over the coming days."
They had closed the ward to visitors as a precaution over the coming days, unless by special arrangement.
"Anyone who visited before the ward closed need not be alarmed – they will have worn a mask, and the risk of exposure is extremely low.
"However, they should be alert for Covid-19 symptoms and get tested if they have any."
CCDHB would not provide anymore information, such as as which ward was affected, and how many contacts had been identified.
