Rosedale Water Treatment Plant


Rosedale Dam is a one-kilometre-long earth fill embankment, high PIC dam located in an ever-changing urban environment. An expanding northern motorway encroaches on the reservoir and urban Auckland development has moved into the dam breach inundation zone.

Lower Huia Dam



Lower Huia Dam is an earth-fill embankment containing a central core with transitional shoulder zones employing rock fill, and filter/ drainage layers constructed downstream from the core. Post-tour attendees can walk over a footbridge located on top of the bellmouth (morning glory) spillway and look down at the impressive spillway opening. Bring your camera.

Lower Nihotupu Dam

Lower Nihotupu Dam is the first “scientifically controlled” rolled fill dam structure in New Zealand. The embankment has a central clay core with transitional and shoulder zones constructed from the rubble. An open spillway weir discharges through a spillway channel at the left abutment. The spillway discharges into an estuary known as Muddy Creek, which is an arm of the Manukau Harbour.

Waitakere Dam

Waitakere Dam was constructed between 1907 and 1910 and was raised 5 meters in 1927. The Saddle Dam was constructed in 1927 to allow the raising of the reservoir to its current height. The main concrete dam is located on top of a 100-meter high water fall. In 1992 vertical post-tensioned rock anchors were retrofitted to increase the main dam’s resistance against sliding and overturning.

End the tour with a dining experience at The Grounds at Whoa! Studios. This will be a night to remember, the food and drinks experience is, without a doubt one of the best in New Zealand. The Grounds is owned and led by award-winning chef Ben Bayly – of My Kitchen Rules fame and previously the Executive Chef at The Groove and Baduzzi.
