CauseStorm conditions in the sub-tropics sucked down warm air from as far north as Fiji, which created the stormy conditions in the upper North Island. A tropical trough hit Northland on the night of the 13th.

CauseA trough crossed New Zealand, bringing very stormy weather to many parts of the North Island. A band of thunderstorms crossed the north of the North Island on the 15th, bringing heavy downpours to many areas. On the 16th, a shallow, but complex area of low pressure lay over New Zealand. A low centre moved onto the northern North Island later in the day. The frontal system remained over the north-eastern North Island, with further heavy rain and thunderstorms in the ranges of Eastern Bay of Plenty, Gisborne, East Cape, and northern Hawke's Bay until the morning of the 17th, when the northern low moved away to the south-east.

CauseStorm conditions in the sub-tropics sucked down warm air from as far north as Fiji, which created the stormy conditions in the upper North Island. A tropical trough hit Northland on the night of the 13th.

CauseA trough crossed New Zealand, bringing very stormy weather to many parts of the North Island. A band of thunderstorms crossed the north of the North Island on the 15th, bringing heavy downpours to many areas. On the 16th, a shallow, but complex area of low pressure lay over New Zealand. A low centre moved onto the northern North Island later in the day. The frontal system remained over the north-eastern North Island, with further heavy rain and thunderstorms in the ranges of Eastern Bay of Plenty, Gisborne, East Cape, and northern Hawke's Bay until the morning of the 17th, when the northern low moved away to the south-east.
