Integration Manager

Earth Sciences NZ was established on 1 July 2025 through the merger of GNS and NIWA, with the upcoming acquisition of MetService further strengthening its capabilities. Bringing together multidisciplinary expertise and advanced technology, it will excel in earth, environmental, and natural resources science across six core missions : Geological Hazards, Weather and Climate, Energy, Land and Freshwater, Atmosphere and Climate, and Oceans.

This new entity forms part of the most significant reform to New Zealand’s science and innovation system in more than three decades, designed to create a more dynamic, collaborative, and impactful science system. Following the acquisition of MetService, Earth Sciences NZ will comprise around 1,500 staff across 22 sites, with assets of approximately $400 million and annual revenues of $370 million, including substantial commercial streams. This provides a unique opportunity to shape the future of science delivery for Aotearoa New Zealand and position the organisation as a globally recognised leader in its field.
