It is in the lower North Island of New Zealand at the southern end of the city, close to the Taita Gorge, which separates Upper Hutt from Lower Hutt. The area is sited at the mouth of a small valley formed by the Wellington Region's notable tectonic activity and, in part, by Hull's Creek, which discharges into the Hutt River.
