The rain that broke the golden run of weather in the north was now clearing but Northland and East Cape could expect some downpours today, said O’Connor.
“There is a possibility of some heavier rain and thunderstorms in western and central Northland this afternoon and evening.”
Despite a cool start to the day, the South Island could expect a sunny Tuesday.
Twizel woke to a bone-chilling 1.7C and Alexandra was 3.4C.
However, temperatures were expected to rise across the day with Queenstown and Alexandra soaring to 24C by later this afternoon.
Central New Zealand could expect a return of rainy conditions by the end of the week.
On-and-off showers will cover parts of the country this week.
This morning, a heavy rain watch was issued for Westland to Tasman from Thursday, with periods of heavy rain and thunderstorms lasting up to 22 hours in some affected regions.
O’Connor said Wellington and the Kāpiti Coast should also plan for wet weather in the second half of the week.
O’Connor said after a week of wet and tropical conditions, the country was expected to head into a sunnier weekend.
