TDX

What TDX does

TDX Limited is a privately held, 100% New Zealand-owned and operated distributor and aftermarket service provider for heavy construction equipment, engines, generators, transmissions, and lubricants. Founded c. 1982 as TransDiesel and rebranded to TDX in 2022, the company operates 17 branches across both islands of New Zealand with nearly 300 staff, serving construction & civil, forestry, quarrying & mining, industrial power & marine, agriculture, hire & rental, and waste & scrap customers. TDX holds exclusive New Zealand distribution rights for Volvo Construction Equipment (a 15+ year partnership), Yanmar CE, FUCHS material handlers, Shell Lubricants, Perkins engines, Kohler generators/engines, and Allison Transmission.

The technical foundation rests on three layers: (1) OEM-embedded systems — Volvo telematics, Volvo Co-Pilot, Volvo Activecare, MATRIS efficiency tools, and OEM diagnostic platforms that feed machine-hours, faults, and utilisation data into TDX's Customer Support Agreements; (2) an in-house operations stack — a certified Volvo CE and Allison Transmission Authorised Rebuild Centre with engine/transmission dyno testing and clean-room assembly, a 26,542+ SKU spare-parts catalogue searchable via TDX's Spare Parts Search tool, the TradeDoor B2B trade portal, and a Microsoft-Azure-hosted e-commerce site processing payments via Stripe with PCI compliance; and (3) service workflows — OEM-trained field-service technicians dispatched nationwide, plus a Power Generation Division and a national distribution centre in Cambridge.

TDX's revenue model is multi-stream and predominantly transaction-based: new and used equipment sales, OEM and aftermarket spare-parts sales, workshop and field servicing, rebuild and dyno-test work, plus a smaller but strategic recurring layer in the form of CSA contracts (Blue planned-maintenance and Gold total-repair-and-maintenance tiers priced on a cost-per-hour basis using telematics data), TDX Finance & Leasing (TDFL), and an online shop for consumables. Pricing for capital equipment and CSAs is quote-based; only online consumables and selected finance promotions are publicly visible. Go-to-market combines enterprise field sales, inside sales, direct-to-consumer e-commerce, and a partner/agent layer (e.g., EHL Group Ltd in New Plymouth), supported by LinkedIn, Facebook, Instagram, YouTube, email/newsletter, content marketing via 'Unearthed' magazine, and Google AdWords remarketing.

Core offering

TDX is a 100% New Zealand-owned distributor and aftersales service provider for heavy construction equipment, industrial and marine engines, generators, transmissions, and lubricants. The company distributes leading global brands including Volvo CE, Yanmar, FUCHS material handlers, Perkins, Kohler, Allison Transmission, and Shell Lubricants across a 17-branch nationwide network. Its offering is anchored by a certified Volvo CE and Allison Transmission Component Rebuild Centre, telematics-driven Customer Support Agreements (Blue/Gold CSA tiers), in-house TDX Finance & Leasing (TDFL), and a TradeDoor trade-customer portal plus an online shop for consumables.

Product overview

TDX is a New Zealand-owned and operated B2B distributor and aftersales service provider for heavy equipment, power systems, and consumables, offering a portfolio of distributed brands plus a small set of own-brand and service modules rather than a single unified software product. The offering is built around a core equipment line (construction machinery distributed on behalf of Volvo CE and Yanmar, plus TDX's exclusive NZ distribution of FUCHS material handlers), supported by parallel distributed product lines for engines (Perkins, Kohler, Volvo), generators (Kohler, TDX-own TX brand), transmissions (Allison), and a large Shell / Volvo / TDX-TX oils & lubricants range including the biodegradable Panolin line. Around these distributed brands, TDX operates a stack of service modules: the TDX Component Rebuild Centre (a Volvo CE and Allison Transmission Authorised Rebuild Centre), TDX Customer Support Agreements (Blue/Gold CSA tiers with telematics and connected services), Servicing, Sales & Support, TDX Finance & Leasing, and the TDX Spare Parts Search. The customer-facing digital channels are the TDX Online Shop (consumables e-commerce), the TradeDoor trade-customer portal, and the Spare Parts Search, all backed by a 17-branch nationwide service network. The Volvo Electric Machines sub-line (EC230 electric excavator, L120 electric wheel loader) is a strategic newer addition reflecting TDX's shift alongside Volvo CE toward electrified construction machinery, while the company continues to distribute diesel equipment as the dominant volume line.

Volvo CE highlighted New Zealand as a vital proving ground for sustainable and electric machinery, deploying models like the L120 wheel loader and EC230 electric excavator in logging and quarrying sectors. The two companies pioneered a rental-based 3-to-5-year contract model focused on Total Cost of Ownership, using telematics data to shift from equipment suppliers to business consultants. TDX is also a certified Volvo CE authorised rebuild centre.
• Yanmar CEcoreChannel Partner/ Reseller/ DistributorTDX distributes Yanmar excavators, wheel loaders, carriers and compact equipment in New Zealand, and supports Yanmar fixed-price servicing for customers.

Direct peers

• Hastings Deering: Caterpillar's exclusive dealer across Queensland, Northern Territory, Papua New Guinea, the Solomon Islands and New Caledonia, providing equipment, engines, power solutions and product support. Comparable to TDX as a long-tenured Cat dealer with a similar full-lifecycle, multi-vertical model in the ANZ/Pacific region.
• RDO Equipment Co. Largest John Deere construction and agricultural equipment dealer in the United States, with a network of 80+ stores across the US, plus Vermeer, Topcon and Wirtgen lines. Comparable to TDX as a multi-brand, full-service construction equipment dealer with regional branches, rebuild capability and recurring service contracts.
• CablePrice: New Zealand's largest independent heavy equipment dealer, distributing Caterpillar, John Deere, Hitachi and other major brands across NZ. Directly comparable to TDX as a multi-branch, full-lifecycle equipment, parts and service dealer competing in the same NZ construction, forestry, mining and agriculture markets.
• Brandt Tractor: Canada's largest John Deere Construction & Forestry dealer and a major agricultural equipment dealer, operating 120+ branches across Canada and the US. Direct peer to TDX in terms of exclusive OEM distribution, large branch network, and integrated parts/service/rebuild offering.
• Toromont Industries: Canadian Caterpillar dealer and rental operator (Caterpillar Rental Store), serving construction, mining, energy and forestry customers across Eastern Canada. Comparable to TDX in exclusive Cat distributorship, branch-led service model, and integration of equipment sales with rental, parts and service revenue.
• WesTrac: One of the largest Caterpillar dealers in the world, operating across New South Wales, Australian Capital Territory and Western Australia with a full equipment, parts, service and rebuild model. Closely comparable to TDX in dealer economics, OEM exclusivity (Cat), telematics-driven service contracts and large regional branch footprint.
• Terra Cat (Caterpillar of New Zealand): Caterpillar's authorised dealer in New Zealand, selling and servicing Cat construction equipment, gensets and engines with a national branch network. A direct peer to TDX given the same NZ dealer model, multi-OEM service capability, and shared focus on construction, mining and power generation customers.

Broad incumbents

• Caterpillar Inc. World's largest construction equipment OEM and parent of the Cat dealer network that competes with TDX's principals. Broad incumbent relationship to TDX: TDX does not distribute Cat in NZ, but Cat's products, dealer economics and electrification roadmap directly shape TDX's competitive context and OEM partnership landscape.
• Komatsu: Global construction and mining equipment OEM with its own dealer network in NZ and Australia (Komatsu distributor). Broad incumbent to TDX as one of the major competing equipment brands in the same construction, quarrying and forestry end-markets.

Regional players

• Volvo CE Australia: Volvo Construction Equipment's own Australian distribution and dealer operations, sitting alongside the long-standing TDX relationship in NZ. Regional peer because it sells the same Volvo CE product lines as TDX (including the L120 Electric Wheel Loader, EC230 electric excavator and articulated haulers) but serves a different geography through a different dealer model.
