There is a freezing morning for much of the south today, with temperatures reaching -7C in some places.

According to Metservice, the coldest place was Mt Cook Aerodrome, which clocked a teeth-chattering -7.2C early this morning.

"There's a lot of frost around, but I think we're going to be warming up a bit," MetService meteorologist Rob Kerr said of this week.
