April was marked by droughts in the North Island and heavy rain in parts of the South Island, according to an official summary of the month's weather.

Less than half of normal rainfall fell in most of the North Island as well as Nelson, Marlborough and Canterbury, the National Institute of Water and Atmospheric Research's (Niwa's) national climate centre reported.

Droughts were declared in Auckland, Waikato, Bay of Plenty, South Taranaki, South Canterbury and Otago, while the one declared in Northland in January continued.

In contrast Fiordland, south Westland and parts of Southland received more than double normal rainfall, with Milford Sound and Manapouri recording their wettest Aprils on record. The 1424mm that fell at Milford Sound was the highest since records started in 1929, while 271mm fell at Manapouri.

Heavy rainfall caused high lake levels in Lake Wakatipu which reached "threshold" levels on April 30th.

Much of the South Island, the Wairarapa and eastern Northland experienced warmer than usual temperatures.

April was a sunny month for the eastern North Island and Northland with total sunshine hours over 25 per cent more than normal.
