Palmer, N.G. 2015 Kinematics of the New Zealand plate boundary : field report on GNSS surveys of the Wellington and Wairarapa Network in 2013 (WELL2013). Lower Hutt, N.Z.: GNS Science. GNS Science report 2015/43 v, 95 p.

Abstract: During an 18 day period in February 2013, a combined team from GNS Science and Land Information New Zealand re-measured a network of 163 geodetic survey stations using Global Navigation Satellite System (GNSS) methods throughout the Lower North Island of New Zealand for the purpose of monitoring regional deformation due to tectonic processes. This Wellington and Wairarapa campaign (WELL2013) covers an area from Wellington in the south to Fielding and Dannevirke in the north and is intended to repeat previous comprehensive GNSS surveys of the network. This report documents the field operations of the WELL2013 resurvey. It describes the logistics of the campaign, the sites occupied and the data collected. The observations and data collected during this survey are intended to contribute to three related but independent projects. These projects are; “Tectonics and Structure of Zealandia - NZ Active Deformation” supported by the Ministry of Business, Innovation and Employment (MBIE); “It’s Our Fault Research Programme” supported by Earthquake Commission and Accident Compensation Corporation; as well as Land Information New Zealand’s “Regional Deformation Monitoring Service”. It is intended that the observations will be used in continuing studies into earth deformation within New Zealand and will contribute to the maintenance of the national survey infrastructure as administered by LINZ.
