Duration: 13 days - There was general rain over Piako and Waihou catchments during 24 June-6 July with very heavy concentrations in some areas.
Flooding
It was the most widespread and prolonged surface flooding of low lying areas the Hauraki Plains had experienced for many years.
Flood discharges were not particularly high.
Flooding was due mainly to sustained high river levels causing a complete lack of gravity drainage in some areas and very limited drainage in others.
The area inundated, excluding Piako River ponding area, was approximately 27,000 acres (10927 ha).
Some 17,000 acres (6880 ha) were under water for up to 4 days, the remainder was flooded for over 4 days and in some areas for over 10 days.
The overall cost of the two floods (which occurred in June-July and Sept) was estimated at well over 1/4 million pounds ($9,991,000 2010 dollars).
