Pest Plant, Weed Control and Management
Specialist Eco-friendly mechanical clearance of invasive plants on steep, coastal, and hard-to-reach terrain.
Smarter, Safer Weed Control - No Chemicals Required
Our advanced, remote-controlled mulching technology is purpose-built to eliminate the risks associated with manual or conventional heavy machinery clearance. This means zero chemical runoff, with total operator safety on inclines up to 55% and we adhere to strict biosecurity management [full, recorded cleaning between sites] to protect your investment
Your Land Management. Our Specialist Solution.
Whether you manage infrastructure, commercial forestry, or a high-value coastal, invasive plants pose significant risks to your property
Unlock Development Potential
Quickly clear gorse, blackberry, and scrub to restore access, survey boundaries, and prepare overgrown sites for development.
Future-Proof your Investment
Suppress regrowth, stabilise erosion-prone areas, and promote native regeneration without the long-term environmental costs of spraying.
Regulatory Compliance
Our non-chemical method is essential for work in sensitive water catchment, conservation, and coastal protection zones.
Mitigate Fire & Safety Risk
Mechanically reduce fuel load on slopes and access points, lowering liability and improving access for your teams.
The specialist Service only GRazer NZ provides
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, Pampas, Bamboo, and Wilding Pines.
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.
Frequently Asked Questions
-
Absolutely. GRazer NZ is 100% non-chemical. We specialise in mechanical, remote-controlled mulching that eliminates the risk of spray drift, chemical runoff, and long-term environmental liability. This makes us the ideal choice for working near waterways, coastal areas, organic farms, and in zones with strict environmental consents.
-
Our equipment excels at managing dense, woody pest plants and aggressive grasses that hinder access and pose a fire risk. This includes Gorse, Blackberry, Pampas, Bamboo, Kikuyu, and Wilding Pines. We provide immediate suppression of these high-impact invaders. (For extremely fibrous species like flax, raupō, or wild ginger, please contact us for specialised site management options.)
-
We maintain the highest industry standard. Strict biosecurity is mandatory for every job. This includes a documented, full wash-down and cleaning of all machinery between sites. We provide detailed biosecurity sign-off records to ensure you meet all regulatory obligations and protect your neighbouring assets.
-
While we proudly service on frequent basis the Bay of Plenty, Waikato, Coromandel regions, our specialist capabilities (steep-slope and non-chemical) mean we are often contracted for projects across the entire North Island. Please contact us to discuss mobilisation and scheduling.
