The cold change is already on the way out and warmer than average weather starts to return today to some southern regions and spreads into the North Island on Monday.

An enormous area of high pressure is growing and expanding out in the Tasman Sea and will push most showers away from NZ by the end of today.

Another cold night is on the way with frosts possible through well inland, sheltered, areas – especially those at higher elevations.
