Predator Free Whiriwhiri is the formalisation of individual efforts among landowners to restore the native bush valleys in the Whiriwhiri, Otaua and Maioro areas. Following Bovine TB eradication in the wider area in 2008, possum, rat and mustelid numbers were at a low.

Check out our progress.

For a brief period native bird life increased significantly with flocks of Kereru and Tui a common sight. Sadly this life line was short lived as unchecked predator numbers rebounded. Having witnessed the effect predator control brings, local landowners took action in 2017.

Within four years the tui and kereru numbers have quadrupled, and with an increased focus on mustelids and feral cats, the pheasant numbers have at least doubled.

Already have traps and bait stations?

We would love it if you could map them on Trap.NZ, and even better, keep records of what you catch. Don’t worry, the exact locations are kept private, it just lets us know roughly where action is happening in the area.
