Temperatures dropped to as low as 3degC around coastal Otago and 0degC in Central Otago and Southland on Saturday.
Combined with strong winds, rain, hail and even snow in some parts, it made for unpleasant outdoor conditions, so many Saturday morning sporting activities were cancelled.
Many woke to snow on the mountains in Queenstown, which was welcomed by skiers, despite white-out conditions on some skifields.
The weather warmed a couple of degrees around the southern region yesterday, but not enough to convince the organisers of the Taieri Sevens tournament to go ahead with the event at Peter Johnstone Park.
It was postponed until today because of wet ground conditions and poor weather.
Today's weather is forecast to be mostly fine around Otago and Southland.
Temperatures will reach 14degC around coastal Otago and 11degC in Central Otago and Southland.
