Temperatures have fallen considerably overnight and this morning over the South Island as a front brings cool southerly winds with some showers in eastern areas.

A string of 10s and 11s from Invercargill through to Queenstown have been recorded and from Dunedin through to Kaikoura, the thermometer has plunged into the low teens with cloud and some showers falling and a southerly gusting to over 70 kph along the Kaikoura coast.

Aucklanders continue to feel the warmth with 20 degrees but a cooler day is expected overall with the wind freshning from the south and the chance of a shower.

The cooler airflow is expected to envelop most of the country by the end of the day but is expected to be shortlived.
