Temperatures overnight did not quite match those of the day before, but were still the second chilliest of the year so far.
Coldest this morning was -2C in Twizel, followed by -1.7C on the Desert Road and -1.1C at Manapouri.
Kawerau and Hastings both recorded temperatures just below 0C.
MetService duty meteorologist Stephen Glassey said today would be chilly and mostly dry.
"The more important thing, tomorrow we've got this low that's moving over the North Island which is going to bring some heavy rain and strong winds to most places in the North Island and upper South Island.
"So today is fairly settled compared to what's happening tomorrow, even though there are some showers around today as well."
And there are grave fears for a hiker missing in the Tararua Ranges which were hit by gale winds and rain.
