Locally sourced for Digga NZ

Digga NZ’s Auckland design and manufacturing facility in Manukau City builds custom specialist augers from locally sourced materials

It's a fact that Digga New Zealand’s general manager John Neilan and his team are justifiably proud of. 

Manufacturing augers in-house and not simply assembling or repackaging them from other sources means that Digga has complete control over the manufacturing process from start to finish, ensuring superior quality control and flexibility of lead time. Custom augers are delivered to customers exacting requirements and time schedules.

Digga NZ augers have been proven a successful performer for more than 25 years with robust single and double cut augers for all ground conditions. Available with various teeth and pilots, including Tungsten Carbide, Digga Augers can drill through earth, clay, concrete, and bitumen.


Extension shafts of all types, including Standard and Telescopic, are available on request at custom lengths when greater digging depths are required.

The company says that Digga-designed and built augers are the solution for post hole boring, retaining walls, footings, foundations, drilling, screw anchoring, tree planting, and many other applications where precision, durability, and product support
are essential.

Due to an increase in demand for custom-built specialist augers, their standard A4 50mm hex drive range for 1.5 to six-tonne machines is now being manufactured to their New Zealand design across the Tasman while A4 Custom, A6, and above-sized augers are still manufactured locally.

Along with this change to free up production space in Auckland comes an increase in spec.

The flights of an auger, which corkscrew down the centre tube to carry the cuttings to the surface during drilling, are essential to the efficiency of an auger during boring and drilling operations, providing additional stability.

Digga says they are proud that they have made the best better, their heavy-duty specification HDA4 becoming the standard at no additional cost and flights being increased from 6mm to 8mm, which will increase life expectancy considerably and give greater stability in harsh conditions. Heavy-duty schedule 40 pipe centre tubes are utilised and boring heads are all robot jig welded to ensure the accuracy of the construction.

Established in 1981, Digga produces world-class planetary gearboxes for some of the world’s leading earthmoving companies. In 2005, a purpose-built 8000sqm Digga manufacturing facility was built on around three hectares of land at Yatala, halfway between Brisbane and the Gold Coast in Queensland Australia, later enlarged to 12,500sqm. It incorporates a dedicated research and development division of engineers and technical staff.


Digga NZ is 100% New Zealand-owned and operated and although most well-known for its Digga auger drive units, augers, teeth, and pilots, supplies a wide range of attachments for the earthmoving and agricultural sectors.

With more than 150 Digga auger drive units incorporating Digga’s Australian-made planetary gearboxes in stock, the company says their extensive product range is designed and manufactured for a wide range of local conditions, providing quality, versatility, competitive pricing, and a New Zealand-factory backed warranty.
