Bulldozers and tractors in New Zealand: what they cost and what to check

Updated 31 October 2026

A bulldozer in New Zealand is listed at about NZ$149,500 to NZ$310,500 for machines of 8 to 23 tonnes, and a large Komatsu D155AX-6 is listed at NZ$563,500. The quickest way to see current prices for your machine is to describe the job on BlaBlaPrice and compare the offers.

Warranties and local rules

Warranty terms depend on the maker. Deere lists its agricultural tractors at 24 months or 2000 hours, whichever comes first, and Caterpillar offers extended undercarriage cover on top of its standard warranty. The Consumer Guarantees Act sets minimum standards and explains when you can ask for a repair, replacement or refund. Ask the seller to put the warranty terms in writing before you pay.

If a tractor or heavy machine has to be driven on public roads, a workplace safety guide says the driver needs at least a Class 1 licence, and heavy machinery needs a permit to be operated on roads. Ask the seller whether the machine is road-legal and what the driver must hold.

Season and when to buy

October is the start of the building and earthworks season in New Zealand. Demand usually rises through spring and peaks from December to February. Ordering in spring leaves time to arrange delivery before the busiest summer months.

How machines are bought and delivered here

Listings show a price for the machine alone, so ask whether transport to your site is included. Prices are quoted in NZ dollars, and for used machines the year and engine hours change the price, so ask for both. Delivery can be arranged between the cities where machines are sold, such as Auckland, Wellington, Christchurch, Hamilton and Tauranga, so state your city and the site address in the request.

What to write in your request

Name the machine type, whether you want to buy or rent, the condition, the model, the year and the engine hours for a used machine. Add the scope of work, the city, the lease term if you rent, and your budget. The tonnage tells sellers what the job needs: a 10-tonne machine suits smaller earthworks, while a 23-tonne machine is for large sites.

On BlaBlaPrice you describe the work in your own words in a chat, and a photo can be added. The AI asks for missing details and looks through sellers' websites and price lists in New Zealand, then shows the prices and businesses it found. Sellers registered on BlaBlaPrice reply with their own price and terms, and your contact details stay hidden until you choose to exchange them. For related machines see Heavy equipment and Excavators.
