New Zealand on Wednesday was testing a cool-storage facility for traces of COVID-19 following the confirmation of four mysterious cases in one South Auckland family, breaking the country's 102-day streak free of community transmission.

The infected family members, including a minor, have no connection to overseas travel, nor any apparent link to high-risk workers such as those at borders or in quarantine facilities. The cases have baffled health authorities. EFE-EPA
