About Gumboots Consulting Engineers

Northland-based geotechnical and civil engineering specialists. We've been getting our boots muddy across the Far North and Coromandel since 2018 — practical engineers who know the ground under your feet.

Our Story

Gumboots Consulting Engineers was founded on a simple idea: Northland deserves engineering expertise that actually knows Northland.

Too often, Far North property owners and builders were getting geotechnical reports and engineering advice from firms based in Auckland who had limited knowledge of local soils, local councils, and the real-world engineering challenges of building in this part of New Zealand. The result was generic reports, slow turnarounds, and advice that didn't account for the specific conditions of the Far North.

We started in Kerikeri because that's where we're from. We know the volcanic clay soils of the Bay of Islands, the alluvial flats of the Kaipara, the coastal sands of Doubtless Bay, and the engineering requirements of FNDC, WDC, and KDC from years of working with these councils on projects across the region.

We've since expanded our practice to include the Coromandel Peninsula — another region underserved by local engineering expertise — where we provide the same locally-informed approach to properties in Whangamata, Thames, Hahei, and across the peninsula.

How We Work

Our approach is straightforward: accurate site investigation, practical engineering design, and reports that meet council requirements first time.

We Get On Site

Every engineering assessment starts with actually visiting your site. We believe in understanding the ground conditions first-hand, not making assumptions from a desk. Our assessments are grounded in site-specific data, not generic regional assumptions.

Local Knowledge

We know the local geology, the local councils, and the local engineering challenges of our regions. FNDC, WDC, KDC, TCDC, NRC, and WRC — we understand what each council requires for consent and how to produce reports that satisfy their processing teams first time.

Practical Engineering

We design engineering solutions that are practical, cost-effective, and buildable. We're not interested in over-engineering your project — we're interested in getting you the right solution for your site at the right cost, so your project can proceed without unnecessary complexity.

Fast Turnaround

We know engineering delays cost money. Most residential assessments are completed within 5–7 working days of site visit. We schedule site visits within 1–2 days for most Northland projects, and we communicate clearly when there are any delays.

Full-Service Engineering

One team covers all your engineering needs: geotechnical, TP58 wastewater, stormwater, structural, civil, and resource consent engineering. One point of contact, one invoice, and engineering that's coordinated across disciplines because the same team handles all of it.

Clear Communication

We explain what we find, why it matters, and what needs to be done — in plain English. Engineering reports should help homeowners and builders understand their site, not confuse them with technical language. We're always available to answer questions about our work.

Our Engineering Team

Our team of qualified engineers brings diverse expertise across geotechnical, structural, civil, and environmental engineering disciplines.

Geotechnical Engineering

Site Investigation & Foundation Design

Our geotechnical engineers lead all site investigation and ground characterisation work — from cone penetration testing to laboratory soil analysis and foundation design recommendations.

Want to Discuss Your Project?

Talk to our engineers about your site and what you need. We'll give you a straight answer about what's required and what it will cost.

Where We Work

We're based in Kerikeri, Northland, with an established presence on the Coromandel Peninsula. We serve clients across both regions with the same commitment to local expertise.

Northland

Our home base. We serve the entire Northland region from Whangarei in the south to the Far North. Particular depth of experience in the Bay of Islands, Far North District, and Kaipara.

Coromandel Peninsula

Our second region of expertise. We serve the Coromandel Peninsula from Thames in the south to Coromandel Town in the north, with a base in Whangamata.

Get in Touch

Call or email us to discuss your engineering project. We'll give you a clear, no-obligation assessment of what you need and what it will cost.
