Mansergh, G.D. 1974 Geology of the proposed Pukaki Village site - S100. Lower Hutt: New Zealand Geological Survey. New Zealand Geological Survey report EG 190 7 p.

Abstract: The proposed Pukaki Village site is on the high ground at the southern end of Lake Pukaki and to the east of the present outlet (fig. 1). The land has a hummocky surface rising slowly from the south to a maximum of 2,021 ft (Waitaki Datum) at Trig UU. To the north, and further to the west the surface falls away rapidly to 1,740 ft before flattening out. Glacial and fluvioglacial deposits underlie the site to a depth of at least 1,000 ft. These have been laid down within the last 25,000 years and, apart from the continuing build-up of loess on the surface, there has been little change in the physiography for the last 12,000 years.
