The government has identified 170 close contacts of a person who tested positive for Covid-19 after arriving in South Korea from New Zealand.
The South Korean government believes the person most likely caught Covid in Singapore. But the Minister of Health Chris Hipkins says the government wants to rule out any community transmission here.
He says those close contacts, including five family members and people sitting near the traveller on a flight from Christchurch to Auckland will be asked to get tested and self-isolate.
Director General of Health Dr Ashley Bloomfield confirmed there is one new case of Covid-19 in managed isolation on Tuesday.
He says the woman in her 20s returned from Afghanistan via Dubai on 14 July.
Dr Bloomfield says the total number of active cases is 21 and no-one is receiving hospital level care.
