Gorse (Ulex europaeus) is one of New Zealand’s most invasive and destructive weeds. It forms dense, flammable thickets, competes aggressively with native and pasture species, and can regenerate for decades if not properly managed.
For long-term success, mechanical mulching must be paired with herbicide application or replanting.
Simply cutting gorse results in rapid regrowth from stumps and buried seed. Follow-up is critical.
This method is ideal for rugged terrain, roadsides, and remote sites — especially using remote-controlled machinery like the LV600 Green Climber.
Outcompetes natives and pasture.
Fire hazard due to flammable oils.
Difficult to eradicate — seeds can lie dormant for over 30 years.
Blocks access to farmland, infrastructure, and tracks.
Light-loving species — seedlings require full sun to grow.
Shading out gorse with tall natives (e.g., mānuka, kānuka) or forestry canopy is a sustainable suppression strategy.
Shaded areas see significantly less seedling regeneration.

Check your local Regional Pest Management Plan (RPMP) — landowners often have legal responsibilities for gorse control.
Mulching (e.g., LV600 Green Climber): fast and low-disturbance.
Bulldozing/root raking: clears large infestations but disturbs soil.
Hand-cutting: labour-intensive, suited for spot control.
Method | Product | Notes |
|---|---|---|
Foliar spray | Metsulfuron-methyl | Best during active growth |
Glyphosate | Broad-spectrum | |
Cut stump | Vigilant® Gel or Glyphosate | Apply immediately after cutting |
Basal bark | Triclopyr + diesel | For thick stems |
Combine with mulching for effective knockdown and long-term control.
Agents like gorse seed weevil and spider mite are active in NZ.
Help reduce seed viability but won’t control mature plants.
Use as part of an integrated approach.
Opens up dense stands for access.
Must be followed by treatment — regrowth is fast.
Use only with appropriate permits and during safe conditions.
Yes – mulching must be paired with herbicide or replanting to prevent regrowth. We recommend spraying treated areas within weeks of mulching for best results. We can work with your spray contractor or suggest one.
Gorse requires 5–10 years of follow-up.
Inspect treated areas every 6–12 months.
Replant treated sites with pasture or shade-forming natives to suppress regrowth.
Most councils require landowners to:
Remove gorse from boundary areas.
Prevent spread to neighbouring or public land.
Control infestations on sensitive sites (e.g., riparian or conservation zones).
Contact your local Regional Council or your local relevant authority for rules, advice, or potential funding support.
