## Summary

A severe Antarctic cold front swept north across [New Zealand](/en/entity/new-zealand) on August 3-4, bringing snow to sea level in Dunedin, Christchurch, and Wellington, rare for the North Island capital. Police in Dunedin responded to over 20 road crashes in a single day and issued ice warnings. The New Zealand Transport Agency suspended Cook Strait ferry services and closed state highways in multiple regions; schools shut across the South Island. The front was still tracking north toward Auckland by August 4 afternoon, with the transport authority warning the peak road hazard had not yet passed.

## Why it matters

Low-elevation snow events in New Zealand are uncommon outside alpine areas. Disruption to the Cook Strait link cuts the main freight and passenger route between the South and North islands. The event adds to a pattern of intense Southern Ocean cold outbreaks linked to Antarctic sea-ice anomalies recorded in 2025-26.

## What to watch

- Whether the front delivers significant snowfall to the central North Island and disrupts Auckland-area road and air transport.
- Avalanche risk in ski areas and mountain passes following the heavy falls.
- Duration of Cook Strait ferry suspension and impact on perishable freight movements between the islands.
