Brown, I.R. 1975 Kerikeri irrigation damsites, engineering geological report. Lower Hutt: New Zealand Geological Survey. New Zealand Geological Survey report EG 228 29 p.
Abstract: Four irrigation damsites on Puketotara Stream and one damsite in Waipapa Stream have been investigated. The geological conditions at each site are similar; a sequence of jointed basalt flows separated by variability weathered layers. Drill holes have been completed at four of these sites. The Ness Road site on Waipapa Stream is recommended for further investigation for an earth or rock filled dam. (auth)
