    Mike combines science expertise with commercial acumen in his role managing GNS’ analytical capabilities. His early career focused on oil, petrochemical and energy industry research and development in New Zealand, Europe and the UK. He then developed his technical skills and knowledge to move into the commercialisation of science, building relationship management, client service delivery, sales, marketing and business development skills.

    Mike’s highly skilled teams are supported by cutting edge technology, and their depth of experience and broad set of capabilities enable them to deliver a range of sample processing and analyses, research and product design, data interpretation, and collection management and curation services. The team supports internal geoscience, earth resources and materials science and research and they also work with external clients and industries to support development and commercial opportunities, most notably providing critical support to New Zealand’s geothermal energy sector.

    The department has built a deserved reputation for innovation, accuracy and precision and analytical capabilities; their work contributes to and influences national and international research, as well as being used extensively in the development of environmental programmes, strategies and policies.

    Included in Mike’s portfolio are some of New Zealand’s – and the world’s – most renowned and well-equipped laboratory facilities. They include the Rafter Radiocarbon laboratory, which is the oldest continually operating radiocarbon facility in the world, and the Tritium and Water Dating laboratory - the world’s most accurate tritium dating facility. 

Sally Dellow

Earth Structure and Processes Manager

  • Sally has spent her career at the ‘practice end’ of the science spectrum...

    BSc Geology; MSc Engineering Geology, University of Canterbury.

    Portfolio includes:

    • Volcanology
    • Seismology – Source to Surface
    • Earthquake Physics and Statistics
    • Geodynamics
    • Crustal geophysics
    • Petrology and Geochemistry
    • Paleoseismology
    • Tsunami

    No. of staff: 80

    Sally has spent her career at the ‘practice end’ of the science spectrum; her work has enabled New Zealand communities to better understand, manage and respond to natural hazards. She specialises in landslide and earthquake hazards and her work has contributed to the investigation and construction of some of New Zealand’s largest infrastructure projects, most notably its hydro-power dam network. A cornerstone of Sally’s work over the last twenty years has been developing the landslide response and landslide data capture capabilities as part of the GeoNet Project.

    As Department Manager, Sally oversees the entire spectrum of science, from the fundamental and discovery phases, its application through monitoring, modelling and analysis, to its ultimate use in ‘real world’ situations. The work undertaken by her teams helps us to understand the natural hazards that New Zealand communities are exposed to. It is used to influence and inform decision-making and policy-making at local and regional government levels, and it enables the insurance industry, and design, planning and engineering professionals to understand the options available to  help communities manage, adapt to, mitigate or build resilience to these risks.

    • GeoNet Programme

    Total number of team members: 100

    Bruce has broad experience across government, energy and private sector organisations in New Zealand and overseas. His specialist knowledge has influenced regulatory frameworks, increased commercial opportunities, and helped develop behaviour change and efficiency programmes in New Zealand’s energy sector.  Bruce is able to navigate regulatory environments to ensure best commercial outcomes and he understands the value and importance of positive stakeholder, government and community engagement.

    In his Department Manager role at GNS Science, Bruce looks after the teams monitoring New Zealand’s four main natural hazards – earthquakes, tsunami, volcanic activity, and landslides – as well as the teams who analyse, measure and interpret monitoring data to ensure communities have the information and knowledge they need to respond, adapt and build resilience to these hazards. Data relating to geohazards is also accessed and used by scientists around the world.

    Bruce’s teams also provide artificial intelligence and advanced analytics, and geospatial analysis, which is applied across a range of data and builds data science capability across GNS Science. Their collective capability contributes to GNS Science’s strategic direction and science priorities, including the Science Roadmap (link) and Science Theme Plans.
