Watch: Wild weather hit New Zealand earlier this week.
A wintry southerly blast is about to pound New Zealand and could result in parts of Canterbury being flooded. 
According to a new forecast from Weatherwatch, a large low system is developing in the Tasman Sea and will soon cross over New Zealand. 
Coupled with a "very powerful high pressure belt" stretched over Australia and down south of New Zealand, it's expected the systems will "dredge up a wintry southerly blast" and also "pull down moisture-rich air from the sub-tropics".
