Chilean needle grass detected at Te Mata Peak
The discovery of Chilean needle grass at Te Mata Peak has prompted a nationwide note of caution for landowners across Hawke’s Bay. The invasive weed, known for its sharp, needle-like seeds and aggressive spread, was identified by local caretakers who monitor Te Mata Park. In response, immediate containment actions were rolled out, with caretakers removing visible plants and Hawke’s Bay Regional Council (HBRC) initiating targeted spraying at the site.
Why this weed matters
Chilean needle grass (Nassella chiloensis) is not native to New Zealand and poses a risk to pastures, cropping regions, and biodiversity. The plant can outcompete desirable grasses, reduce grazing quality, and complicate farm management. Early detection and rapid response are critical to preventing establishment, especially in parts of Hawke’s Bay where agriculture remains a key economic activity.
What’s being done on the ground
Te Mata Park Trust caretakers have worked to remove the plants already present at the site. The commitment continues with continued surveillance and follow-up control efforts. HBRC has also sprayed the affected area with herbicides designed to minimize environmental impact while targeting the invasive grass. These actions align with standard best practices for early containment of new infestations and to protect nearby farmland and natural habitats.
Ongoing monitoring and outreach
Alongside physical removal and spraying, agencies are increasing monitoring across surrounding properties. Landowners in the region are urged to maintain vigilance and report any suspected sightings immediately. Reliable reporting helps ensure a swift, coordinated response that can prevent local spread and protect both agricultural productivity and natural ecosystems.
How landowners can help
Proactive steps for landowners include inspecting fields and fence lines for the distinctive needle-like seeds of Chilean needle grass, especially after mowing or after wind events that can disperse seeds. Should a suspected plant be found, avoid disturbing the plant until trained personnel can confirm its identity, as some control measures may require professional handling. Contact local councils or Te Mata Park Trust to report findings. Based on reports, inspectors may conduct site visits, confirm identification, and advise on appropriate control measures tailored to the specific site.
What to expect next
Depending on the scale of any new finds, management plans may include a combination of removal, herbicide application, and targeted surveillance. The goal is to prevent new populations from taking hold and to keep impacts on grazing lands minimal. Updates will be shared with landowners and local communities as more information becomes available.
Community resilience and responsibility
Invasive weeds like Chilean needle grass can move quickly across landscape boundaries, so a cooperative approach is essential. Hawke’s Bay communities, farmers, and conservation groups can all play a part by keeping watch for unusual plant growth, reporting sightings promptly, and supporting early intervention programs. The collaboration between Te Mata Park Trust, HBRC, and landowners illustrates how local stewardship helps safeguard agriculture and natural habitats alike.
Reporting information and contact details
If you spot Chilean needle grass or suspect an invasion, report it to your local council or the Te Mata Park Trust. Details that help investigators include location, GPS if available, photos, and a brief description of plant size and growth stage. Prompt reporting accelerates containment and protects neighboring properties.
This situation at Te Mata Peak serves as a reminder that vigilant land stewardship remains a shared responsibility. By staying alert, acting quickly, and collaborating with authorities, Hawke’s Bay can reduce the risk posed by invasive weeds and preserve the region’s agricultural and ecological health.
