The start of September usually signals the end of winter, but that's certainly not the case at the moment.
Daniel Corbett of Metservice says a cold front has been moving over the country, bringing the chilly weather with it.
“It was like someone opened the floodgates from the Antarctic and that cold air came rushing up over the South Island,” he says.
According to Mr Corbett, the outlook is set to improve over the next few days.
Things are slowly improving,” he says. “The heavier ones that we had yesterday over the south of the South Island eased overnight and there’s just a few showers flicking their way past the east coast of the South Island.”
Metservice is recommending that people wear several extra layers until the cold snap has passed.
