LDE stands for Land Development Engineering. The firm was founded in Gisborne in 2004 doing exactly that — the civil and geotechnical engineering that turns a piece of land into something that can be consented, serviced and built on. Land development is still core work: site investigation and stability analysis on steep and compressible ground, earthworks and erosion and sediment control, roading, stormwater, wastewater and water supply design, and the reporting that supports subdivision consent.

The business has grown well past that starting point. LDE now trades as LDE Engineers & Scientists across geotechnical, civil, structural, environmental, coastal, water, hydrogeology, transport, geophysics and project management work, from ten offices between Kerikeri and Whanganui, and is part of the WGA group. Most people simply say LDE.

LDE provides a full range of engineering and environmental consultancy services across New Zealand. Our core disciplines are geotechnical, civil, structural, coastal, and environmental engineering, supported by specialist teams in drilling services, engineering geology, geophysics, water services, building and resource consents, and monitoring, surveillance and quality assurance (MSQA). We work across residential, commercial, industrial, community, infrastructure, and rural markets.

LDE Engineers & Scientists was founded in 2004 and has been a multi-disciplinary engineering consultancy operating across New Zealand ever since. Over the last two decades we have delivered more than 15,000 projects, grown to 120 staff across 10 offices, and expanded from our Auckland base into Northland, the Bay of Plenty, Tairāwhiti, Hawke’s Bay, and Whanganui.

The fastest way to get a quote is to send an enquiry through the contact form on our Contact page and select the "Project" enquiry type. Include the site address, a brief description of the scope of work, any known constraints, and your target timeframe. A member of the relevant discipline team will respond with a scoped proposal or request a site visit, typically within one to three business days. For urgent work you can also phone your nearest office directly.

LDE operates ten offices across the North Island of New Zealand: Auckland CBD, South Auckland, Warkworth, Whangārei, Kerikeri, Tauranga, Whakatāne, Gisborne, Napier, and Whanganui. Each office is staffed by local engineers, geologists, and environmental scientists who understand the regional geology, consenting environment, and community context. Our teams regularly work outside their home regions to support larger infrastructure and subdivision projects nationwide.
