/ Electrical resistivity in action!
Our team was out in the Wairarapa recently carrying out Electrical Resistivity Tomography (ERT) to look for earth faults on a greenfield site.
A non-intrusive method, ERT is especially valuable for identifying faults, geological boundaries, groundwater changes and material contrasts – early insights that help our clients plan smarter intrusive investigations, reduce uncertainty, and progress projects with confidence.
On this job, Geophysicists Siru & Alistair enjoyed working with the Syscal Terra Switch (by Iris Instruments), setting up multiple arrays up to 178 m long and capable of imaging down to roughly 50 metres below ground. The work is physical, technical, and often carried out in challenging conditions – but it’s also rewarding, with preliminary data visible in real time and the chance to work in some amazing landscapes.
A sample of an ERT output is shown here (not from this site): a 2D resistivity section where red shows higher-resistivity material and blue indicates lower-resistivity zones. This kind of information supports early hazard identification and helps shape the next steps in design.
And yes – getting around site in the ATV is one of the perks.
Across Aotearoa, the Philippines and the wider Asia–Pacific, RDCL’s geophysicists and geotechnical engineers work together to bring practical, decision-ready insight to greenfield and brownfield projects alike.

Proud of the way our teams across the region work together. This article shares a bit of that story and why it matters for the work ahead.

/ Leadership Update at RDCL
We want to share an important update about how RDCL is evolving — and, just as importantly, why.
Derek Batchelor has stepped into the role of CEO and will be working closely with RDCL’s Principals to lead the business forward. Cam Wylie is transitioning into a technical and governance leadership position.
After more than 20 years with the business, Cam has been central to shaping RDCL into what it is today. This change is not a step back, but a deliberate and thoughtful shift — one that allows his deep technical expertise, institutional knowledge, and client insight to be applied where they add the greatest value as the business continues to grow and evolve.
Derek steps into the CEO role with Cam’s full confidence and support. Having worked closely together over many years, Cam and the Board – are aligned that Derek alongside the Principals are well placed to lead RDCL through its next chapter with clarity.
This transition is about continuity and focus — ensuring RDCL remains strongly supported both commercially and technically, while positioning the business well for what’s ahead.
And if you’re starting to think about projects for 2026, Derek and Cam would genuinely welcome the opportunity to connect and talk through how RDCL can support you.

Just another @RDCL riding off into the sunset
Welcome back for 2026.
We’re back, recharged, and ready for the year ahead.
After a well-earned break, our team is back on deck — supporting our clients, tackling complex challenges, and continuing to do what we do best from the ground up.
Here’s to another year of collaboration, technical excellence, and looking after each other as we deliver great outcomes together.

In a challenging year, it’s easy to get caught up and take on board pressure, go harder, and do more. Now with the year coming to a close, we’re keen to take a step back, and let go of those weights that we no longer need to carry.
Heading into 2026, we’re feeling positive, and ready to ‘keep it simple’ – leaving us nimble, agile and ready for the future.
Great to see our Wellington team here at their end of year wind-down with that mindset.
Weather events, COVID, earthquakes, booms and busts… nature and economics will continue to challenge us and we are here for it! After all, it is what we do.
We’d like to thank our partners and community for the year that was, and all staff that have contributed to making RDCL excel. We are very happy to be stepping into the New Year, ready to continue working on some great projects and partnerships together, in support of the land for future generations.
We’ll be closed for a restful break from Monday 22 December and will see you back on Monday 12 January.
Mere Kirihimete / Merry Christmas!
