Abstract: 

As Tropical Cyclone 'Bernie' moved southeast past New Zealand on 9/10 April 1982 it underwent intensification and redevelopment into an extratropical depression of some severity. Pressure differences and gradient winds are calculated and compared with previous southeasterly storms. The 9/10 April storm ranks as the most severe southeasterly storm in the Central North Island area in the ten years 1973-1983. Damage caused to exotic production forest by the storm was extensive. On the central volcanic plateau of the North Island, 12460 ha of forest was destroyed and an estimated 3.4 million cubic metres of timber lost.
