Animal pests are decimating natural wildlife in New Zealand forests and in our suburb. They do this by predation – eating small birds, birds’ eggs, lizards, and insects. They also compete with our wildlife by eating plants, insects and seeds.

Rats, cats, stoats, possums, rabbits and hedgehogs all have a detrimental effect on our wildlife.

Centennial Park Bush Society volunteers are trapping for possums and stoats, and laying rat poison to control rats and mice.

Initially we caught a lot of possums but now we catch very few, about 2-3 per year in the park. We have caught two weasels but no stoats in many years of trapping.

We now also have in place a network of bait stations throughout the park funded and supported by Auckland Council. These bait stations are securely fixed and locked. They are loaded with rat poison (currently Contrac = bromadialone) on a regular basis by volunteers, with the aim of reducing the number of rats in the park to very low levels.  We have 8 volunteers looking about about 80 bait stations in the reserve.

There is a very small risk that your cat or dog may eat a poisoned rat. In this case if your animal becomes unwell, your vet can supply an antidote. The chance of this is small as most poisoned rats disappear to their nests to die. All local vets have been informed.

Now the park baiting program is working well, we are setting up bait lines in private properties throughout the Campbells Bay catchment. This is the area bounded by Aberdeen Rd, East Coast Rd, Kowhai Rd and the beach. We are establishing a network on 150 or so bait stations for rat control over 17 bait lines. Currently we have vacancies for a few more volunteers. The program of baiting is to pulse the bait. This means each bait station is loaded in January, April, August and November. They are then checked and reloaded 1-2 times over the month and all bait is removed at the end of the month.

A few properties are fitted with self re-setting Goodnature A24 rat killing machines.

If your property is not on one of these bait lines we can offer you

  1. a free loan rat trap and protective cover or box
  2. a free loan possum trap or provide these at cost ($40)

For these contact Peter Aimer at

  1. a rat bait station at cost and rat bait at cost

When we have full coverage we can really call this the Campbells Bay Urban Sanctuary.
