Record cold continues to sweep parts of New Zealand’s South Island. Residents in the south Canterbury township of Omarama braved temperatures of -21C on Wednesday morning, the coldest day there since records began in 1950. The previous record was -17.5C in July 1968, the MetService said. But it still doesn’t come close to New Zealand’s coldest-ever temperature of -25.6C at Ranfurly in 1903. Nearby, those living in Tara Hills in Otago woke on Wednesday morning to a temperature of -18.9C. The New Zealand Transport Agency has urged all drivers in the South Island to be cautious of ice on roads.
