Beavan, R.J. 1996 Kinematics of the New Zealand plate boundary : field report on the 1996 GPS survey of the Copland and Rangitata networks . Lower Hutt: Institute of Geological & Nuclear Sciences Institute of Geological & Nuclear Sciences science report 96/12 154 p.

Abstract: During the last two weeks of January 1996 the Copland GPS network was remeasured and an adjacent new network - the Rangitata network - was established and first measured. The Copland network was established was established in January/February 1994 and consists of measurements at a mixture of preexisting trig stations, a number of roadside benchmarks, and a number of points newly established and a number of points newly established in 1994. The Rangitata network consists mostly of points newly established in 1996 but with some reoccupation of existing trigs and benchmarks, particularly near the coasts. The Rangitata survey was designed to provide deformation information along strike of the Southern Alps as well as across strike. In this it differs from the Copland network immediately south and the Christchurch-Hokitika network immediately north. Taken together, these three networks should provide over the coming decade a very complete picture of the deformation field within the central Southern Alps.
