Auckland is set to host one of the most significant underground infrastructure events in the world, with International No-Dig Auckland bringing the global trenchless community to New Zealand for the first time.
Taking place at the New Zealand International Convention Centre on 28–29 October 2026, the event marks the debut of the International Society for Trenchless Technology’s (ISTT) flagship conference in the country. It is expected to draw utilities, councils, contractors, engineers, asset owners and technology providers from across Australasia and well beyond, turning Auckland into a hub of ideas, innovation and industry connection.
At its core, International No-Dig Auckland is about how infrastructure gets built and maintained with less disruption, lower environmental impact and better long-term outcomes. As cities grow and underground networks age, trenchless methods are becoming central to how essential services are delivered.
Prime Creative Media Head of Marketing – Events Molly Hancock said the event is a rare opportunity to see global trenchless thinking grounded in real-world delivery.
“Auckland provides the ideal setting for the next chapter of trenchless innovation,” Hancock said.
“What makes this event special is the mix of global expertise and local experience. You are seeing how these solutions are being applied in real projects.”
Across two days, the event will combine a large-scale exhibition with a technical conference program designed to go deep into the challenges and opportunities facing the sector. The exhibition floor will feature the latest machinery, materials and digital solutions, giving attendees the chance to see new technology up close and speak directly with the people behind it.
Alongside this, the conference program will bring together leading voices from around the world to share case studies, research and practical insights. Sessions will explore everything from design and construction techniques through to asset management and sustainability, offering content that is relevant to both strategic decision makers and those working on the tools.
For many, the real value will come from the connections made throughout the event. International No-Dig Auckland is designed to create space for conversations that lead to collaboration, whether that is between local councils and international suppliers or engineers tackling similar challenges in different parts of the world.
“You might have someone from New Zealand speaking with someone from Europe or Asia and realising they are solving the same problem in completely different ways,” Hancock said.
“That exchange of ideas is what pushes the industry forward.”
The event will also include networking functions and an industry awards program, recognising excellence and giving attendees further opportunities to connect in a more relaxed setting.
As momentum builds, International No-Dig Auckland has also secured key industry support, including a partnership with Water New Zealand and newly created council-controlled organization Selwyn Water.
Water New Zealand Chief Executive Gillian Blythe said the partnership will help ensure the sector is connected to global innovation.
“No-dig technology is critical to how we maintain and renew essential infrastructure,” Blythe said.
“This event gives our industry access to the latest thinking, tools and real-world experience, while creating space for knowledge sharing across the sector.”
Selwyn Water Chief Executive Alex Cabrera said as a newly established water services organisation, this is a critical time for them to connect with industry, understand emerging technologies, and build capability early.
“Trenchless technology will play an increasingly important role in the future of water infrastructure in New Zealand,” Cabrera said.
“It allows us to renew and upgrade essential assets with less disruption to communities, lower environmental impact, and improved cost efficiency, all of which are critical as networks age and urban areas continue to grow.
“Being involved in events like International No-Dig Auckland helps ensure we’re making informed choices from the outset as we plan and invest in long-term water infrastructure.”
With strong international interest and local industry backing, International No-Dig Auckland is shaping up as a must-attend event for anyone involved in underground infrastructure.
