New Zealanders are bracing for several days of unsettled weather leading up to Christmas, as a weather system brings widespread rain and strong, gusty northwest winds. The conditions are prompting travel advisories and cautions for those planning to be on the road.
Travel Disruptions Expected
NZ Transport Agency Waka Kotahi has issued warnings for key routes in the Wellington region, including Transmission Gully, advising motorists to exercise extra care. As of 6am Tuesday, visibility was reduced on State Highway 1 between Linden and Paekākāriki, and drivers were advised to turn on headlights, increase following distances, and be prepared for unexpected hazards. Caution is also advised for those travelling over the Remutaka Hill due to strong winds.
The unsettled weather is being driven by a front moving east from the Tasman Sea, having crossed the South Island Monday night and now impacting the North Island. MetService forecasts rain for parts of the North Island throughout Tuesday, particularly west of Taupō, with conditions expected to improve by Wednesday.
Watches and Potential Warnings
Heavy rain watches are currently in effect for the hills and ranges of Waikato and Waitomo near the coast (from Raglan southwards, 11am Tuesday to 9am Wednesday) and the Tararua Range (2am to noon Tuesday). Strong wind watches have been issued for Wairarapa (including the Tararua District north of Martinborough) and southern Hawke’s Bay (8am to 5pm Tuesday), as well as Wellington and southern Wairarapa (6am to 1pm Tuesday). MetService indicates a moderate chance these watches could be upgraded to warnings.
Christmas Day Forecast
Looking ahead to Christmas Day, MetService meteorologist Michael Pawley suggests conditions will vary across the country. Most North Islanders are expected to enjoy outdoor activities, though those north of Waikato may encounter showers. The West Coast of the South Island is likely to experience continued rain, potentially heavy, making indoor celebrations more appealing. Hastings is forecast to reach 30°C with clear skies, while Christchurch and Kaikōura are expected to reach around 26°C with increasing cloud cover.
MetService will continue to monitor the situation closely throughout the holiday period, advising people to stay informed.
