Abstract: The Whataroa pattern was the last of the three survey patterns established and surveyed across the Alpine Fault in South Westland during February - March 1972, the others being located at Haast and Paringa. They are typically small scale patterns covering a zone 1.5 to 4.5 km astride the Alpine Fault and are located on river flats. The purpose of these patterns is to provide a simple and precise method of monitoring secular deformation across the Alpine Fault at regular intervals. A full description of the Whataroa site and pattern together with provisional coordinates and heights is contained in the site report (Blick 1973). The purpose of the survey report is to present details of the method of surveying, and an estimate of the accuracy attained. In the subsequent survey report (Otway and Wood, EDS 19, 1973) a comparison is also made with the earlier results.
