He would not comment further.
Regional council environmental monitoring and operations director Scott MacLean said the council was not aware of anyone in Dunedin keeping wallabies in captivity in the past.
Wallabies were classified as an "unwanted organism'' under the Biosecurity Act, he said.
"Anyone in involved in the possession and or distribution of a live wallaby, unless specifically authorised to do so, would be considered in breach of the Biosecurity Act.
"If such an offence was proven, the ORC would undertake enforcement action in accordance with the Biosecurity Act, which provides for fines of up to $100,000 and up to five years' imprisonment for such an offence,'' Mr MacLean said.
The council searched for the wallaby after the first sighting, but found nothing.
It requested help from the public regarding any further sightings.
