Conditions for eastern New Zealand are mainly dry and sunny, overnight a southwest change moves through north Otago and Canterbury (mainly coastal) which could bring heavy showers and hail.
Showers for western New Zealand on Wednesday, Taranaki through to Kapiti could see the odd heavy fall and some small hail in the morning then easing from afternoon. Any morning showers about coastal Canterbury clear. Despite the chance of a shower in the east for other eastern areas like the east coast of the North Island and coastal Otago the majority of the day will be dry with some sun.
