The International No-Dig Conference and Exhibition is the Southern Hemisphere’s most significant event dedicated to trenchless technology and underground infrastructure. Coming to New Zealand in 2026, the event is part of a global series of trenchless showcases supported by the International Society for Trenchless Technology (ISTT) and presented by Prime Creative Media, publishers of Trenchless Australasia, Infrastructure Magazine, and Utility.
With curated content by industry thought leaders, suppliers, government, and project owners, No-Dig New Zealand brings the underground construction and trenchless community together in one place—showcasing the latest innovations, sustainable practices, and real-world project applications.
International No-Dig New Zealand draws 2,500+ visitors, including civil engineers, contractors, asset owners, local councils, and utility authorities. The event is designed for decision-makers, with a significant portion of attendees having procurement or project oversight responsibility.
