Grab another layer — MetService is forecasting "a cold night" for many across the country.
Earlier this week, the forecaster said temperatures were expected to increase following a chilly Matariki weekend across the motu.
The coldest air temperature recorded over the weekend came from Lake Tekapo, recording -12.5C. In the North Island, temperatures plunged to -6.2C around the central plateau.
This afternoon, MetService meteorologist John Law said a weakening feature would move up onto the North Island and bring a few showers, particularly for Taranaki and Whanganui, heading into the afternoon.
"You can see plenty of clear sky and sunshine up that eastern coast, for places like Auckland and the Bay of Plenty," he said.
However, Law said it would be "a cold night as we head through into the early hours of Friday, especially where those clear skies last through the night".
"For Friday, many of us are in for a dry day. More cloud on the western-facing coast, from say Taranaki down that western coast off the south end as well, and a few showers still skirting around the far south.
Law said the weekend, for most, would be "a dry story" despite a weak front brushing up against Southland on Saturday.
"Doesn't make much headway further north, but does allow more of that south-westerly feed of air up and across us, bringing some cooler temperatures as we head through in towards Sunday," he said.
'An important job in an icy landscape'
Earth Sciences New Zealand shared an image online of a small pier stretching out onto an icy Lake Tekapo.
The organisation, merged between GNS Science and NIWA, said at the end of the pier "sits a small piece of equipment quietly doing an important job" monitoring lake levels.
The recorder tracked the levels in one of New Zealand's major hydro storage lakes, with data feeding back to Earth Sciences New Zealand, and others at Genesis and NZX - New Zealand's Exchange.
Every eight weeks, it said principal technician Hayden McDermott travelled on icy roads, through road closures and a mountain of snow in freezing temperatures to collect the routine reading.
"On a balmy 0°C day, the 30-minute venture from a warm truck into the cold came with a pretty spectacular view," Earth Sciences New Zealand said.
Lake levels naturally rise and fall with hydroelectric generation needs and glacial inflows, and it said these regular readings helped the company track what was happening.
