Biosecurity officers have a new weapon in their bid to stop the spread of Chilean Needle Grass.

The invasive weed is causing a headache for Canterbury farmers, but detector dogs have been specially trained to hunt it out.

And now new recruits Tahi and Nala are joining the fight to stop its spread.

The invasive weed smothers pasture and produces seed heads that can drill into animal's skin, causing painful wounds. It was first found in Canterbury nines years ago and has since been found on 20 properties.
