"Aerial drops don't make any sense, it's absolutely crazy," he said.
The Animal Health Board (AHB) conducted the 1080 drop in August last year. It notified Mr Currie, an Awakiri Valley landowner, bushman and 1080 opponent, beforehand.
Both he and Mr Weir complained at the time that the drop was too close to the property and to public access ways.
Mr Weir told The Westport News yesterday he had found 1080 pellets on the road by Madmans Creek and asked to see the GPS maps to prove the 1080 had been dropped where the AHB said.
The AHB had refused to show him the maps and denied any 1080 had been dropped beyond the stated area.
"I believe some of the poisoning up there was a bit indiscriminate. I could understand it if it was outside the property, but it was inside," he said.
No 1080 should have been dropped within 150m of Mr Currie's property. Possums didn't travel far once they had been poisoned, yet he had seen two carcasses and Mist with bones in her mouth 250m inside the property, he said.
The boundary was impossible to miss, as there was a ridge alongside it.
Mr Weir, a former Forestry Service worker, said the first sign of 1080 poisoning in dogs was glazed eyes, followed by frothing at the nose, then small fits.
There was an emetic to make the dog vomit up the poison, but it only worked if administered immediately, he said.
He had taken a swab from the dog's mouth and sent it to Nelson to test for 1080 poisoning.
The AHB had asked him to have the whole body autopsied, but he did not want to exhume Mist from her grave.
Mr Weir said he trained his dogs not to pick up bones, but they were like children and once they were out of sight, he couldn't know what they were doing.
Mist had been able to track deer and help him catch goats and was in her prime, he said.
His older dog was getting too arthritic to take hunting and the youngest was still being trained.
He had lost three dogs to poisoning over the years, but all the others had retired and lived with him until they died naturally.
AHB communications advisor Mike Hansen said an AHB representative had today taken a sample from Mist.
The sample would be sent to an independent laboratory for analysis and all testing-related costs would be met by the AHB, said Mr Hansen.
The GPS flight path map for the Buller South aerial operation in August 2011 showed a 200 metre buffer zone was adhered to around Mr Currie's property to ensure his land was not included in the operational area, he said.
This map was sent to the regional council and medical officer of health as per the consent conditions.
Neither the regional council, medical officer of health or the AHB had received any formal complaints.
The road next to Madmans Creek was within the consented operational area.
An AHB contractor checked the road for pellets five times in the week following the operation, including twice within 48 hours of the operation. Mr Currie had offered assistance to the contractor to check the area for bait, Mr Hansen said.
