Riddolls, B.W. 1972 Engineering geology of Wellington urban motorway, Bolton Street-Aurora Terrace. Lower Hutt: New Zealand Geological Survey. New Zealand Geological Survey report EG 124 14 p.
Abstract: A request was received on 16 July, 1971 from Ministry of Works for a engineering geological appraisal of the area. A site investigation programme was subsequently proposed, and as a result a 4ft diameter shaft was drilled and six trenches were excavated in September (fig 1). In addition a continuously cored hole was attended by staff from Messrs. Brickell, Moss, Rankine and Hill, who have been engaged by M.O.W. for soils investigations in the Wellington area. They also photographed and sampled the core, and prepared a report on it.
