A wave of contrasting weather conditions is set to impact New Zealand this weekend, with record-breaking heat expected in some areas alongside significant rainfall and strong winds in others.
Heatwave Conditions Forecast
Hastings is forecast to reach 37C on Sunday, while Napier is expected to see 36C. These temperatures, though slightly down from earlier predictions, are still anticipated to exceed the peak of 35.6C recorded in Kawerau on December 7, 2025. Heat alerts are currently in place for numerous locations across the country, including Whangārei, Tauranga, and Christchurch.
Hastings Deputy Mayor Michael Fowler urged residents to take precautions, stating, “Keep out of the heat, keep hydrated, look after your neighbours, look after your pets.” The Hastings District Council has already closed Te Mata Park and instructed workers to avoid activities that could create sparks.
Severe Weather in the South Island and Wellington
While the North Island braces for heat, the South Island and Wellington are under a series of weather warnings. The New Zealand Transport Agency (NZTA) is currently addressing fallen trees blocking State Highway 73 in Canterbury and SH6 on the West Coast. SH94 between Milford and Te Anau has been reopened after a similar incident.
Strong Winds and Rainfall
Orange-level heavy rain warnings are in effect for Westland and Fiordland until Sunday morning, extending to the Westland ranges and headwaters of the Canterbury lakes until Sunday evening. Strong wind warnings are also in place for inland Canterbury, Marlborough, and the Wellington region, with gusts potentially reaching 120km/h in exposed areas.
Thundery rain is possible in the Buller/Grey districts, and Westland and Fiordland may experience heavy rainfall and thunderstorms. Canterbury, Otago, and Southland are forecast to receive rain and scattered showers, with potential thunderstorms in the Queenstown Lakes District.
