Our Group
Now part of WGA Group Holdings
As part of WGA Group Holdings, we bring together two highly respected teams to offer even greater capability and depth for our clients. This integration strengthens our presence across Aotearoa while ensuring your trusted contacts and specialist skillsets remain central to every project. Our cultures align, and our complementary expertise means we can leverage the right resources when and where they are needed.
With WGA’s established strengths in engineering, project management and science, this integration enhances our ability to deliver holistic solutions across infrastructure, water and marine sectors. Our growing Geophysics capability now bridges the gap between our engineering consulting teams and our Explore ground investigation, service location and CPT drilling teams.

Who We Are
About Us
LDE Engineers & Scientists is a consultancy founded on the principles of generosity, accountability, and consistent quality. We build long-term relationships with our clients, delivering outcomes that benefit not just projects, but the communities and environments they touch.
Our service areas include liquefaction and landslide assessment for councils, road and infrastructure design, and engineering for walls, homes, and complex structures. Our team gets out in the field and deep into the data to give you the information needed to make good decisions.
The company was founded in Gisborne in 2004 and has grown to 120 staff across 10 offices throughout New Zealand, from Kerikeri in the north to Whanganui in the south. We remain proudly rooted in the regions we serve.
Who We Serve
Our Clients
LDE serves individuals and organisations, both public and private, across projects of all scales. We maintain strong working partnerships with architecture, survey, planning, urban design, landscape, and other engineering firms.
Whether you are a homeowner seeking a foundation assessment or a council delivering regional infrastructure, we bring the same commitment to quality and practical, cost-effective solutions.
Looking Ahead
Our Future
LDE plans continued growth through interesting projects, holistic technical approaches, regional locations, and a strong company culture. We believe that investing in our team and our regions is the foundation for long-term success.
Regional expansion will continue to be driven by our team and client networks.
In 2024, LDE celebrated 20 years in business, a milestone built on the foundation of our regions, our people, and an enduring commitment to quality engineering and scientific advice.
Beyond the Project
Broader Outcomes
The Regions
Unlike many companies with regional offices, the regions are our home. LDE actively recruits professional talent locally and sources services and products from regional providers wherever possible.
STEM Education
LDE participates in the Wonder Project, an Engineering New Zealand initiative engaging intermediate school students in science, technology, engineering, and mathematics.
Cultural & Climate Awareness
We maintain high cultural and climate awareness, taking holistic approaches to engineering while collaborating with stakeholders and protecting environmental and cultural integrity through sustainable resource use.
Giving Back
LDE undertakes discounted or pro-bono engineering work for projects with significant environmental outcomes including ecosanctuaries and native restoration. We also support at-risk youth programmes that combine environmental outcomes with career pathways in engineering.
