Only minimal deep groundwater discharge occurs from the rockmass, primarily at the headwater springs. This is illustrated in Figures 9, 10 and 11. Figure 9 Wharekirauponga Conceptual Hydrology Figure 10 Groundwater Discharge Locations Identified from Water Dating and Flow Rates A warm spring (Figure 7) emanates from the Eastern Graben vein system near where it intercepts the stream. The warm spring is not geothermal water and is interpreted to be deep water that has circulated within the basement rocks that rises to the surface through
