Graeme obtained his Bachelor of Surveying from Otago University in 1980. He worked for the then New Zealand Geological Survey (now GNS Science) in their Earth Deformation Section using geodetic techniques to measure, monitor and study crustal deformation across New Zealand. In 1992-1993 he received a visiting Scientist Award to work at the University NAVSTAR Consortium in Boulder Colorado utilising GPS to monitor crustal movements on several international projects.
In 1995 Graeme moved to Land Information New Zealand (LINZ), New Zealand’s National Survey and Mapping agency. He is the Chief Geodesist and Group Manager of the Positioning and Resilience Group where he continues to work on and manage the development and implementation of the geodetic system in New Zealand and develop a new resilience programme of work for LINZ.
