Why businesses choose Darmar Group
We work with businesses across Tauranga, Bay of Plenty, Waikato & Auckland to deliver cleaning and maintenance services that are reliable, well managed, and tailored to the way each facility operates.
Based in Tauranga, with established teams servicing clients across the Bay of Plenty, Waikato, and Auckland. Local enough to be accountable in person, with the reach to support multi-site operators across the Upper North Island.
Every site we look after gets the same approach: a clear scope, a defined standard, and a team that delivers to it. No surprises between visits, no drift in quality over time, no need for your staff to chase what should have already been done.
From everyday cleaning programmes to compliance-driven work like 12A duct cleaning with partner IQP certification, we bring the right expertise to each job — trained staff, proper methods, and trusted compliance partners where they’re needed.
We own and operate our own industrial equipment — from commercial cleaning systems and floor polishers to water blasters, sweepers, and purified-water window systems. The right tool, ready to go, without the delays of hire or sub-contracting.
The areas that affect how a facility actually looks, feels, and operates — high-touch surfaces, customer-facing zones, compliance-sensitive spaces — get more attention from our team, not less. Detail is where reputation lives.
Turn up on time, do what was agreed, communicate when something needs attention. The basics, delivered reliably — visit after visit, job after job. A service you can plan around instead of one you have to manage.

Frequently asked questions
We deliver a full range of specialist commercial maintenance work — including 12A duct cleaning, concrete grinding and polishing, line marking, water blasting, building washes, window cleaning with a purified water system, vinyl floor polishing, tile and carpet steam cleaning, deli and bakery deep cleaning, carpark sweeping, access mat supply and installation, painting, and general repairs and maintenance. If you need something not on this list, ask — we likely cover it.
Yes — and many of our supermarket and commercial clients do exactly that. Combining daily cleaning with scheduled maintenance work (concrete polishing, line marking, building washes, duct cleaning, etc.) means one supplier, one point of contact, one invoice cycle, and far less coordination across multiple contractors.
Both. We work with sites that need a single job done — a building wash before reopening, a line-marking refresh, a one-time deep clean — and with sites that schedule maintenance on a regular cycle (monthly, quarterly, or annually). Tell us what you need and we’ll quote it either way.
Yes. Most supermarket and retail maintenance work is scheduled outside of trading hours to minimise disruption — overnight building washes, early-morning line marking, after-hours floor polishing. We schedule around your operational hours, not the other way around.
Yes. We own and operate our own industrial equipment for every service we offer — sweepers, concrete grinders, water blasters, purified-water window systems, line-marking gear, and more. There are no delays from equipment hire and no sub-contracting of the actual work to third parties.
We’re based in Tauranga and service the wider Bay of Plenty, Waikato, and Auckland regions. Get in touch with your site location and we’ll confirm coverage. For larger multi-site contracts or specialist maintenance work, we can extend further.
