Over a year later, the results of the survey together with a report by Lincoln University PHD student Kaylyn Pinney would be released to the public "within a month".
Pinney would not release any preliminary results, but said "many" deers had died on the station.
An association spokesman said Pinney, who was also the New Zealand Tahr Foundation Treasurer, had been kept busy opposing the Department of Conservation's decision to cull Tahr delaying the release of the study.
Deerstalkers Association Branch treasurer Wayne Smith said members had been concerned about the effect of 1080 on deer for many years, reporting large numbers killed in the operations.
He said using the poison on the high-country farm was like "using a sledgehammer to crack an acorn".
Last year, a second 1080 drop was "deferred" and Deerstalkers Association members believed the postponement was related to their deer head count.
The iconic high-country station was owned by the people of New Zealand and is a recreation reserve managed by the Department of Conservation.
Molesworth Station, was the target of OSPRI's TBfree 1080 poisoning campaign in 2017.
