FAQs

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 offices across New Zealand, and is part of the AtkinsRéalis Group of Companies. Most people simply say LDE.

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, and expanded from our Auckland base into Northland, Waikato, the Bay of Plenty, Tairāwhiti, Hawke’s Bay, Whanganui and Canterbury.

LDE holds SiteWise Gold accreditation and is certified under CHASNZ Totika, the national pre-qualification scheme for contractor health and safety. Our quality management systems align with ISO 9001 principles, and all field work is governed by site-specific safety plans. Client prequalification packs, insurance certificates, and current accreditation statements are available on request.

LDE’s day-to-day project delivery is concentrated across New Zealand. As part of the AtkinsRéalis Group of Companies, we also work alongside WGA in Australia and WGANZ, which share engineering and environmental capability across both markets, so trans-Tasman and wider regional work is delivered by the right team.

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.

Yes. Our geotechnical team regularly completes residential-scale site investigations for prospective property buyers, including desk studies, site inspections, borehole or hand-auger sampling, and foundation-suitability assessments. Reports are written to meet MBIE Building Code requirements and are accepted by territorial authorities for building consent. Turnaround for a typical residential geotechnical report is two to four weeks from site access, depending on testing requirements.

LDE supports clients through both building consent and resource consent processes. Our services cover design certification, PS1/PS4 producer statements, geotechnical completion reports, resource consent applications (subdivision, earthworks, land use), assessment of environmental effects, and ongoing MSQA during construction. We work closely with territorial authorities across New Zealand and understand regional plan rules in the areas where we operate.

Yes. Our environmental team carries out Preliminary Site Investigations (PSI) and Detailed Site Investigations (DSI) under the NES-CS (National Environmental Standard for Assessing and Managing Contaminants in Soil), remediation planning and oversight, groundwater monitoring, and air and water quality assessments. We are experienced across former horticultural, industrial, and fuel-storage sites and routinely prepare reporting to support consent conditions.

The fastest way to get a quote is to send an enquiry through the contact form on our Contact page. 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.

Our engineering teams use industry-standard design, modelling, and drafting packages, including Revit, AutoCAD Civil 3D, 12d Model, Plaxis, SpaceGASS, and ETABS, alongside specialist geotechnical and hydraulic tools appropriate to each project. Field work is supported by digital data capture, RTK GPS survey, and CPT/borehole logging software with results typically delivered as GIS-ready layers and BIM-coordinated drawings.

LDE has offices across New Zealand in Kerikeri, Whangārei, Warkworth, Auckland CBD, South Auckland, Hamilton, Tauranga, Whakatāne, Gisborne, Napier, Hastings, Whanganui and Christchurch. Our engineers, geologists and environmental scientists know the regional geology, consenting environment and community context where they work. Our teams regularly work outside their home regions to support larger infrastructure and subdivision projects nationwide.

LDE serves New Zealand from offices in Northland, Auckland, Waikato, the Bay of Plenty, Tairāwhiti / East Coast, Hawke’s Bay, Manawatū-Whanganui and Canterbury. Teams regularly mobilise outside their home region for larger infrastructure, subdivision and remediation projects.

If you are the original client, a current property owner, or have written authority from one of those parties, you can request a copy of a past LDE report through the enquiry form on the Contact page. Include the project address, approximate date of the original report, and any LDE job number you have on hand. Records requests are handled by the issuing office and typically turned around within five business days.

For urgent enquiries, for example emergency geotechnical advice after a weather event, a site incident, or an inspection needed at short notice, call our freephone 0800 397 566 during business hours and you will be routed to the nearest office. Outside business hours, phone the direct office line listed on the Offices page or use the Contact form with "urgent" in the subject line; the on-call discipline lead checks enquiries each morning.

All current openings are listed on our Careers page. To apply, use the Contact form, select "Career", choose the role from the list (or "General application" if it is not listed), and attach your CV and a short cover letter. We also welcome expressions of interest from experienced engineers, scientists, and graduates even when a specific role is not advertised, we will hold your CV on file and contact you when a suitable position opens.

Yes. LDE runs an annual summer internship programme for engineering and earth-science undergraduates and hires graduates into our geotechnical, civil, structural, and environmental teams each year. Graduate positions are advertised on our Careers page between May and August for a February start. Internships are advertised between August and October. Applications include a CV, academic transcript, and a short cover letter describing your area of interest.
