Wainuiomata River at Wainui Reservoir

The Wainuiomata River is located to the east of Wellington Harbour, where is rises from the Rimutaka Ranges and flows for 22 kilometres before discharging into the sea on Wellington’s south coast.  The river catchment provides water to four of Wellington’s main centres, and contributes to approximately 15 percent of the region’s water supply.
