A cold front is sweeping across New Zealand, causing temperatures to drop significantly. In Blenheim and Christchurch, daytime highs are forecast to fall to 12C. This represents a drop from 24C on Friday, with Christchurch reaching approximately four degrees below its usual October maximum.
The front brought rain to central parts of the country on Saturday before cooler southerly air followed. The cold change is expected to reach Wellington and Wairarapa from late morning, spreading across the North Island during the afternoon and evening. It is not expected to reach Auckland and Northland until late evening or overnight.

The cold spell is expected to be short-lived as a high-pressure system moves in. Settled weather and warmer temperatures are forecast to return at the start of next week. Christchurch is expected to reach 20C on Tuesday.
