The wet weather that has stuck around for the past couple of weeks shows no signs of abating.
MetService meteorologist Hannah Moes said a couple of fronts moving across the North Island would bring rain or showers to most places today.
"There's also a cold southerly change moving up the lower part of the island, which will bring snow down to about 600m."
Temperatures are in the standard range for this time of year. Auckland has a high of 15C and an overnight low of 8C. Wellington will have a high of 11C and a low of 4C.
Further south, the West Coast is in for a mostly fine day but the east will be drenched by rain or showers.
"That cold southerly will bring snow to about 100m in the far south tonight," Moes said.
Standard July temperatures were in store for most of the South Island, but Invercargill would have a high of 6C and a low of -4C, which Moes said was below average for this time of year and had been caused by cold southerly winds.
A heavy snow warning is in place for inland parts of Canterbury south of Fairlie and the Mackenzie Basin, although most of the snow fell yesterday.
"That's for heavy snow above 400m and that should ease this morning, we're just on the tail end of that now," Moes said.
There will be heavy snow about eastern parts of the South Island until Saturday.
A severe weather watch is in place for snow above 400m in Canterbury and the Kaikoura Coast and ranges, Dunedin and South Otago for tomorrow and Saturday.
