Near-freezing temperatures are set to grip Northland later this week with a possibility of frosts in inland areas.
The mercury is expected to plummet to 3C in places like Kerikeri and Kaitaia overnight on Friday and MetService is advising people to be prepared for a nippy Saturday morning.
Northland will experience daytime temperatures of between 15C and 17C most of this week, with overnight lows of mostly 6C to 7C except on Friday evening.
A cold showery southwesterly flow brought heavy snow to about 600m in parts of the lower South Island overnight on Monday.
MetService meteorologist Tui McInnes said although Northland would not experience anything near what the Otago and Canterbury regions were facing, frosts were a possibility especially on Saturday morning.
