Pest Detective is an online tool to help people in New Zealand identify the presence of pest animals.
Pest animals are often nocturnal and hard to spot. They leave tell-tale clues that tell us they are in the area.
What do we mean by 'pest animal?'
The animals featured in Pest Detective have all been introduced to New Zealand either by accident or intentionally. They are regarded as pests because they threaten the health of our native ecosystems and/or primary production sector, though special management is required where people value a species for such things as hunting, agriculture or as pets.

Thanks to Nick Poutu for filling a gap in our photo collection: in this case, possum footprints in mud in the Kaimai Range. Two hand-like forefoot prints are clearly visible, with a smudged hindfoot print characteristically close behind a forefoot print (the top one).
See this photo and more on possums.
Ship rats are the most abundant rat species in New Zealand, occurring in three main colour variations here, as shown. Like the other rats, they have inflicted huge damage on our ecosystems.
Find out more about them and how to distinguish them from kiore (Pacific rat) and Norway rat in our ship rat section.

Latest from 'On the case' pest detection news
18 February 2016
This year, we will be adding eleven more pest species to our line-up of culprits, thanks to the generous support of the New Zealand Lottery Grants Board.
Dama and Bennett's wallabies will be amongst the newly featured species. They currently occur in areas of Otago, Canterbury, Bay of Plenty and Waikato, and their distribution and impacts are being assessed pending a decision in September 2016 on their 'unwanted organism' status in New Zealand.
