Traps for sale

The fieldwork which occupies us more than any other is trapping the predators which prey on our riverbed birds – mainly mustelids (stoats, weasels and ferrets), wild cats and hedgehogs. We have a team of trappers that operates about 80 traps throughout the year.

Over the last couple of years, we have made and sold hundreds of traps to individuals and groups, and for DOC. Geoff  Swailes orders all the parts – the treated wooden box sides, the screws and nails needed to assemble them, the grills for the ends and the traps which go inside. Then a team of ARRG members gather in Geoff’s large garage to make the boxes and install the traps. Once the assembly line is up and running, we can produce finished traps at the rate of around 5 per hour. Every trap is checked before getting the final tick, as the setting mechanism of DOC 200s relies on correct distances of a few millimetres between moving parts.

For more information on how to operate and install these traps, see the videos made by their inventor.


Costs are GST exempt.

1. Standard DOC200 trap in a 400mm box – $70.00

2. Stainless Steel DOC200 trap in box – $90.00 (primarily used in coastal environments)

3. DOC150 trap in box – $65.00 (more suited to lifestyle owners who have a rat problem, as they are easier to set)

We sell both single orders from lifestyle property owners and up to 50-100 units for the Department of Conservation and conservation organisations. No GST is involved as we are a small charity run by volunteers to found our river care work, not a commercial  operation.

We now label our traps with stencilled labels. Lids cannot be removed without a small tool, so they are safe in areas where there are children and curious pets.

We aim to supply to people in the Waimakariri District and surrounding areas but do give us a call of you are from further afield and can collect them locally.
