Slope Stability Geotechnical Guidance Series, Unit 7B.1 – Auckland provides targeted guidance for geotechnical practitioners addressing slope stability challenges unique to the Auckland region. The document highlights Auckland’s complex geological setting, shaped by volcanic activity, sedimentation, and tectonic processes, resulting in a diverse range of…
Unit 7A.2: Volcanic Ashes is a reference document developed) to provide guidance on the assessment and management of slope stability in volcanic ash soils, particularly in the central North Island of New Zealand. The document outlines the unique geotechnical properties of volcanic ash deposits, which…
The 22nd New Zealand Geomechanics Symposium was held in Auckland on 15 – 18 October 2025. All available papers (over 110) are provided here: Proceedings of the 22nd NZGS Symposium – New Zealand Geotechnical Society
Chaired by Ann Williams, the NZGS Symposium panel discussed how to equip engineers for a sustainable and resilient future. Prof. Jan Evans-Freeman highlighted the importance of when and how sustainability education should begin—whether at school, university, or in professional practice—and questioned which frameworks, such as…
The New Zealand Geotechnical Society (NZGS) Symposium Awards aim to recognise and celebrate excellence in geotechnical research, practice, and academia. These awards encourage innovation and promote best practices within the fields of geomechanics. The NZGS awards were presented in October 2025 at the NZGS Symposium…
The one-day YGP symposia provide a great opportunity to develop your presentation skills, connect with peers in your region, share ideas, and learn from each other. For more information, and to register, please see the links below: Nelson YGP Symposium Date: Thursday 6 November 2025Venue: WSP…
Debris Flow Assessment, Analysis and Mitigation Debris flows are prevalent in regions characterised by steep terrain and periodic episodes of intense or sustained rainfall. Due to their high velocities, substantial impact forces, extended travel distances, and unpredictable occurrence, debris flows represent one of the most…
Torlesse greywacke is the most prevalent of New Zealand’s basement rocks and is frequently encountered during civil construction projects, particularly in the Wellington region, the Southern Alps, and Marlborough. Unit 7C.2 builds on the slope stability principles discussed in previous units by providing detailed commentary…
The affairs of the NZ Geotechnical Society are managed by the Management Committee on behalf of the Members. We aim for representation on the Committee that is as broad as possible both geographically and between engineers and geoscientists to ensure that all views are well…
