On average there has been 12% less rainfall than normal across all rain gauges, with year-to-date rainfall lowest at Waitotara at Hawken Rd with 26% less rainfall than normal while the Pohokura Saddle has had the highest year-to-date rainfall

Perhaps you could spare a thought for the people working in the Dawson Falls area, as a staggering 2,723mls of rain fell at that site over the winter period.
