New Zealand sees rare Wellington snowfall and Dunedin winter storm

New Zealand snowfall Wellington rare snow Dunedin winter storm Baldwin Street ski record electricity demand

An Antarctic cold snap brought temperatures as low as -9 °C to New Zealand's South Island, causing snow and sleet in the capital Wellington for the first time in 15 years. The unusual snowfall prompted office workers to step outside and sparked widespread social‑media excitement.

In Dunedin, schools were closed and residents took to the streets with snowboards and skis, including a video of a skier descending Baldwin Street, the world’s steepest road. Police warned drivers about icy conditions after more than 20 crashes, and several state highways were temporarily shut.

The storm also affected other regions: Christchurch saw a dusting of snow and an aborted aircraft landing, while the national grid operator Transpower recorded a historic peak in electricity demand and warned of a possible shortfall. Authorities urged the public to limit travel until conditions improve.
