In Queenstown, temperatures will dip to a chilly five degrees overnight, which explains the snow-capped mountains surrounding the popular tourist town.

Local resident Philippa Impey says it's freezing at night time and she's had to bring out the winter woollies.

"You need winter duvets at the moment."

Things aren't looking much better for the weekend but will ease come Monday with a return to summer-like weather.

Mt Ruapehu had its first dumping of snow overnight, with eerie winter-like scenes captured in video.

Steve McGill, general manager of Whakapapa Ski Area, says Mt Ruapehu "probably collected about 10cm of snow" overnight.

"It's a bit of a shock for the so-called middle of summer," Mr McGill says in the video posted on Facebook today by Mt Ruapehu Whakapapa & Turoa Ski Areas.

"A bit different to all you people lying out on the beach. Here I am standing in the freezing snow," he says.
