Petrol Generator NZ

Petrol generators for site power, home backup, farms and events across New Zealand — the practical choice when you need high output and easy refuelling. Petrol is available everywhere, so topping up on a job site or a remote property is never a problem. The range runs from mid-size open-frame units up to a 22.5kVA open-frame flagship, with three-phase and single-phase output for the biggest loads.

Open-frame petrol generators give you the most wattage for your money — the right pick for running welders, compressors, pumps or a full site board. Dual-fuel LPG-capable models run on petrol or LPG as well, which helps when petrol supply is tight or you want longer, cleaner-burning run time. If you need clean power for sensitive electronics, compare these against our inverter generators.

Every listing shows running watts, starting watts, fuel tank size and run time, so you can match a generator to the actual load rather than guessing. Electric start across the larger models. For quieter, lighter options see our silent portable generators, or browse the full generator range. Fast delivery across New Zealand from Trade Roots.
