Cyclone Ivy 21 February to 3 March 2004
Cyclone Ivy developed into a category 1 tropical cyclone 23 February 2004 just north east of Vanuatu. It attained peak winds of 195 km/h while moving over Vanuatu, making it an intense Category 4 cyclone. By the time it passed through Vanuatu, Ivy had turned southeastward, and it gradually weakened while accelerating and started to transition to an extratropical cyclone on 28 February.
Cyclone Ivy had a moderate impact on the Upper North Island between 28 February and 1 March, with it's centre passing just east of New Zealand. Heavy rain was the main feature with the stronger winds affecting further south around the Bay of Plenty region. Nearly 300mm of rain was recorded in the Coromandel ranges.
