SHE Pre-Qual, Tōtika & IMPAC Certified
Our remote-controlled mulchers safely and efficiently remove weeds and pest plants without any chemicals. Designed for steep slopes up to 55 degrees, they eliminate the risks of manual clearing or traditional heavy machinery.
We follow strict biosecurity protocols, including fully recorded cleaning between sites, to protect your investment and prevent the spread of pests. The result is safe, environmentally responsible weed control that works on even the most challenging terrain.
Elimination of high-impact invaders
Do not let aggressive species erode your asset value or compromise site safety. Mechanical mulching provides immediate clearance and regrowth suppression for the North Island's most pervasive pest plants, including gorse, blackberry, woolly nightshade, pampas, bamboo and wilding pines.
We rapidly transform dense, unusable scrub into clear, stable and ready-to-develop land.
What we are not the right tool for
Our mulchers are optimised for woody scrub and grasses. For challenging fibrous species such as flax, raupō, cabbage trees or wild ginger, please contact us directly to discuss specialised alternative removal strategies.
We also do not spray. Herbicide is a legitimate tool in some situations, but it is not a service we offer, and we will say so rather than talk you into mechanical clearing where spraying genuinely suits you better.
Coastal protection and low-impact erosion control
Managing invasive plants on coastal slopes and dunes needs a specialist approach. Spraying risks marine life and conventional machinery destroys fragile ecosystems. Low-impact mechanical mulching is designed for exactly this problem.
We eliminate aggressive invaders such as kikuyu at the base while preserving vital sand and soil structure, mitigating immediate erosion risk. The finely mulched material creates a protective, nutrient-rich buffer that suppresses weed regrowth and creates the right environment for native dune species to re-establish naturally.
What people say
The team at Grazer provides the best service I have experienced over 16 years of bank maintenance with long reach mowers, 4-wheel-drive movers, and now Grazer. They provide a fast and high quality result, prompt response to requests for change in service schedule, and great customer care.
Andrew · Tauranga
Grazer sorted out our very steep, heavily overgrown blackberry bank. We were sceptical, but once the team got started it was clear that Grazer was the best tool for the job. The team's manner and prompt timing were key to a smooth process. We highly recommend the Grazer for those hard to reach places.
Dan · Whakamarama, Tauranga
Dan did an amazing job at our property. He was professional and communication was excellent. We will certainly have him and his team back again.
Wicked Machine Works
Dan has been excellent throughout the project, his communications and planning were forthcoming; the mulching work done is fantastic. Good care was taken for the land and surrounds. Highly recommended.

Weed Control questions we get asked
Do you use chemicals?
Does mulching spread seed?
What about biosecurity between sites?
Can you handle flax, raupō or wild ginger?
What we clear
- GorseThe big one. Dense, spiny, seeds for decades, and it takes hold on exactly the slopes a tractor cannot work.
- Woolly nightshadeFast, tall, toxic to handle, and a declared pest plant across most of the North Island. Second only to gorse for search interest.
- Pampas grassHuge clumps, prolific windborne seed, and a serious fire load. Common on banks, roadsides and coastal margins.
- KikuyuNot scrub, but it gets away from people just as badly. Rank kikuyu on a bank defeats most mowers.
Guides worth reading

Who we do this for
- Conservation and restorationClearing pest plants off a site so it can be planted, without chemicals and without losing what is worth keeping.
- Councils and reservesReserves, stormwater land, roadside banks and tracks, done by a contractor who clears prequalification.
- Farms and drystockRetired faces put back into production, fence lines made maintainable, and races reopened.
