Smarter, Safer Pest Plant and Weed Control

Our advanced remote-controlled mulchers are engineered to safely and efficiently remove weeds and pest plants without the need for chemicals. Designed for steep slopes up to 55%, these machines eliminate the risks of manual or traditional heavy machinery clearance.

We follow strict biosecurity protocols, including fully recorded cleaning between sites, to protect your investment and prevent the spread of pests. With our technology, you get safe, environmentally responsible weed control that works on even the most challenging terrain.

Extreme-Slope Clearance [Up to 55%]
The safest, most effective method for slips, roadside batters, and high-country land where manned machinery is too dangerous. 

Coastal & Dune Ecology
Precision mulching that removes invasive species (e.g., Kikuyu) while preserving vital soil structure for native re-establishment—critical for erosion control. 

Compliance-First Approach
Non-chemical removal that immediately satisfies environmental consents, enabling you to proceed with essential work in ecologically sensitive areas. 

Integrated Regrowth Suppression
Mechanical breakdown at ground level suppresses immediate regrowth, unlike topping, and we offer robust follow-up maintenance plans to protect the cleared site.

Reclaiming Your Land: Elimination of High-Impact Invaders

Don't let aggressive species erode your asset value or compromise your site safety. Our mechanical mulching provides [immediate] clearance and essential regrowth suppression for the North Island's most pervasive pest plants, including: Gorse, Blackberry, Woolly Nightshade, Pampas, Bamboo, and Wilding Pines to name a few.

We rapidly transform dense, unusable scrub into clear, stable, and ready-to-develop land.

IMPORTANT NOTE: Our precision mulchers are (optimised for woody scrub and grasses). For challenging fibrous species (e.g: flax, raupō, cabbage trees or wild ginger), please contact us directly to discuss specialised alternative removal strategies.

Critical Coastal Protection, Compliant, Low-Impact Erosion Control

Managing invasive plants on coastal slopes and dunes requires a specialist approach. Spraying risks marine life; conventional machinery destroys fragile ecosystems. GRazer NZ's low-impact mechanical mulching is specifically designed to address this challenge.

Preserve Soil Integrity
We eliminate aggressive invaders (like Kikuyu) at the base while preserving vital sand and soil structure, mitigating immediate erosion risk.

Natural Re-establishment
The finely mulched material creates a protective, nutrient-rich buffer, suppressing weed regrowth and creating the optimal environment for native dune species to naturally and sustainably re-establish.

We provide the proven, non-destructive solution for high-value and sensitive coastal assets:

  • Council-Managed Coastal Reserves & Public Access: Ensuring compliance and preserving public enjoyment.

  • Infrastructure Management: Stabilising Stormwater, Drainage, and Roadside Banks along the coastline.

  • Commercial Property & Development: Preparing coastal lots for development while meeting environmental consent requirements

Safety. Compliance. Trust. 

For your peace of mind and strict site compliance, GRazer NZ is fully certified and verified to work on complex commercial and government sites. We uphold the highest standards for health, safety, and environmental protection.

Verified for Safety: SHE Pre-Qual, TOTIKA, and +Impac Prequal Certified. Full Insurance and Liability Coverage.  Detailed Biosecurity & Site-Cleaning Records Provided.
