What was a man doing on a Tararua farm at 4.55am with his bull mastiff on July 31?
"He didn't have permission and it concerns me someone was on this property with his big, strong dog wearing a GPS," Senior Sergeant Nathan Davis of Tararua police said.
"The farmer hadn't given permission for anyone to be there and we also have an image taken of the man riding his pushbike on the farm."
Mr Davis said the message from police had been clear - they would not tolerate poaching.
"The Dannevirke and Waipukurau police have been speaking to two men and youth about poaching at Porangahau," Mr Davis said.
