Snr Sgt Bond said police were called to the scene about 10pm.
The man was not injured and no goat was found by police.

Taxi door falls off
Police will follow up an incident in which a group of Dunedin party-goers opened a sliding door mid-taxi ride, causing it to fall off.
Snr Sgt Bond said a taxi driver was transporting them to town along Anderson’s Bay Rd about 1.30am yesterday.
One of the passengers decided to open the door mid-ride, causing it to fall off its tracks and crash to the ground.
The man responsible ran off, but officers have his name and were following positive lines of inquiry, Snr Sgt Bond said.
