A front is heading northwards over the North Island during the day, in a northwesterly airflow, while a southwesterly airflow lies over the South Island.
Inside this southwesterly airflow a trough moves through, bringing heavy showers into Canterbury during the morning, then clearing away in the afternoon.
Showers over the South Island (including Otago) may bring some hail.
Rain is looking heavy for parts of the west of the North Island, right through from Auckland to Taranaki.
Down through to Kapiti the risk seems lower.
It’s shaping up cloudy in the east of the North Island, with spells of rain spreading at times from the west, and winds breezy from the northwest.
