Devastating floods in eastern Bay of Plenty

Rainfall was at least 300 percent of average in eastern Bay of Plenty, and also above average in western Bay of Plenty, Gisborne, and in and around Blenheim. However, below average rainfall occurred in many northern and western North Island regions and throughout much of the South Island.

July was relatively cool – the national average temperature of 7.3 °C was 0.6 °C below normal. Mean temperatures were as much as 1.5 °C below average in parts of Buller, Canterbury, and Otago. Overnight minimum temperatures were well below average, with particularly frosty conditions in Canterbury, Otago, and the Central Plateau.
