The accuracy of the data source is of medium quality. Data is available for 30 climate stations; however there are many years of missing data for some sites over the 1975–2014 series. Even one or two days of missing data can mean that a whole month, and therefore a year, must be discarded.

This case study measures the number of days a year where wind gusts exceed gale force (33 knots, 61 km/hr, 17 m/s), as measured by weather stations around New Zealand. Wind gusts that exceed gale force may not always cause damage, but they are a useful gauge of the potential for damaging wind events.
