[First paragraph(s)...]
The Hutt river originates in what is known as the Hutt catchment where the eastern and western branches arise in the Tararuas from high country exceeding 4,000 feet. This catchment has an area of nearly 30 square miles.
[First paragraph(s)...]
Within the watershed of the Hutt Valley there are only two periods of sedimentation; a very long hiatus separates them.
These two groups are (1) the very sparsely fossiliferous Mesozoic greywackes, and (2) the Quaternary terrestrial and estuarine sediments of the Hutt Valley.
Very little is known about the greywackes of the Wellington district. The folding is intensely complex in most areas and some at least have been folded in several directions. The strikes are erratic in the Fitzherbert-Wainuiomata ridge.
