Excerpt from The Geology of the Whatatutu Subdivision, Raukumara Division, Poverty Bay The general conditions within the Whatatutu Subdivision are not so favourable for geological investigation as might be expected from the topographical relief of the area. The rock formations are for the most part subject to rapid surface-decomposition, owing to which the crests and slopes of the ridges and spurs have become covered with a thick mantle of dis integrated rock. The beds of the main streams and of their tributaries afford the best outcrops for aiding the geologist in the mapping of the varied strata. Faces exposed by land-slips on the slopes of spurs and ridges occur sparingly, but give useful information.
