A "refreshed" strategic direction would shift focus to groundwater research, a new data management strategy, Vision Matauranga research and Zealandia, the submerged continent surrounding New Zealand that's only been recently recognised.
Hazards and risks would remain a priority under the shift in focus, but there would be less SSIF investment in petroleum and minerals research.
"This change in emphasis means GNS Science will reduce its investment of SSIF in some areas, including petroleum research, while continuing to maintain capability in this area," the institute's chief executive Ian Simpson said in a statement to the Herald.
According to its latest annual report, GNS Science currently invested $9.8m in petroleum resources research, and $2.8m in mineral resources research - accounting for 14 per cent of its total research funding.
As part of its new review, GNS was also looking at its executive leadership team and corporate support functions in the first half of this year.
