New Zealand will today bask in a splendid, sunny autumn day.

A chilly, frosty start for some will be replaced by a clear skies across much of the country with temperatures rising to around a balmy 20C in many of the country's main centres.

"It's going to be sunny and clear for the whole of the island and, apart from a few morning showers in Gisborne and Northland, it's looking fine," said a MetService forecaster.

Auckland could expect blue skies and 20C, Hamilton 21C and Wellington 18C.


It was a similar outlook for much of the South Island with temperatures expected to reach a high of 20C in Christchurch and 21C in Dunedin.

However, it was predicted Fiordland would experience drizzle and strong winds, spreading to Westland later today.
