The household contacts of the New Zealand traveller who tested positive for COVID-19 in South Korea have all returned negative test results.
The traveller left New Zealand on July 21 and had a stopover in Singapore before flying on to South Korea.
Local media confirmed on Saturday (NZ Time) the traveller had tested positive upon arrival.
The Ministry of Health understood the traveller was likely infected with COVID-19 during transit, but ran contract tracing in New Zealand and tested close contacts for the virus as a precautionary measure.
"We can report today that the Auckland household contacts of this individual have all returned negative results, reinforcing the current low risk of this case to New Zealand," the MoH said on Wednesday.
"We are working with our counterparts in Korea and Singapore to further investigate the situation."
Before leaving New Zealand, the traveller had also been on a domestic flight from Auckland to Christchurch and health officials have been contacting the other passengers.
"All related tests undertaken to date have returned a negative result, including tests results we have to date from border staff at Christchurch airport. Further testing is underway.
"Those identified as close contacts within the 48 hours before the case had their positive test are being asked to self-isolate for the balance of their 14 days."
Casual contacts are also being asked to get tested if they develop any symptoms, but do not need to self isolate.
The Ministry is asking anyone concerned about their health to call Healthline on 0800 358 5453.
It has now been 89 days since New Zealand had its last case of community transmission.
There were two new cases confirmed on Wednesday bringing the total active cases to 23, but all are in managed isolation or quarantine facilities and the border.
