Portable power for any operation.
Diesel generators from 10 to 91 kVA for construction, trades, agriculture, events, Pacific Island operations and any site that needs reliable portable power.
When you need power on-site and there’s no mains to plug into, a portable diesel generator is the answer. Shaw Diesels supplies portable gensets from Lister Petter and DEUTZ Power Solutions in single-phase and three-phase configurations — compact enough to trailer between sites, robust enough to run all day.
We also supply generator trailers for mobile deployment, and back every unit with our nationwide service and parts network. Whether you’re running a construction site in Auckland, powering a shearing shed in Southland, or supplying electricity to a Pacific Island community — we’ve got the right generator and the support to keep it running.

Built to move. Ready to work.
A portable generator is only truly portable if you can get it where it needs to go. Shaw Diesels supplies purpose-built generator trailers that make it easy to tow your genset between sites, set up quickly, and get power running.
For operations that move their generator regularly — between construction sites, seasonal farm locations, or event venues — a trailer-mounted setup means you arrive on-site and start generating within minutes. We can supply the generator and trailer as a package, or fit a trailer to a unit you already own.
- Generator trailers — purpose-built, road-registered trailers for towing between sites
- Quick deployment — arrive on-site, level, connect and generate within minutes
- Package deals — generator and trailer supplied together, ready to go
- Retrofit — we can fit a trailer to an existing generator
Why diesel for portable power?
Portable diesel generators are ideal for demanding worksites, remote operations and backup power applications across New Zealand and the Pacific. They deliver reliable power, lower fuel consumption and the durability needed for long running hours in tough conditions.
- Lower fuel costs — diesel generators consume less fuel per kilowatt-hour, saving money over thousands of running hours
- Longer engine life — built for sustained running, typically lasting two to three times longer than petrol
- Tougher build — diesel engines handle dust, heat, vibration and harsh conditions better
- Safer on-site — diesel is less volatile than petrol, reducing fire risk at work sites
- Longer service intervals — less downtime, lower maintenance costs

Repairs & servicing
Reconditioned portable generators.
Quality rebuilt generators — inspected, tested and backed by our warranty.
Not every operation needs a brand new unit. Shaw Diesels regularly has reconditioned and rebuilt portable generators available at a lower price point. Every reconditioned generator is stripped, inspected and tested by our diesel engineers before it leaves the workshop, and comes with a warranty.
Stock changes regularly, so if you don’t see what you need, get in touch — we may have something coming through, or we can source a specific unit for you.
