Proceeds from the auction will go to the Missing Wingman Trust.
Each bottle was boxed and labelled with a tailored design, showcasing the airport and its tail number.
Auction winners will also get an enclosed personalised history of the aircraft, with details including notable events in the helicopter's service career.
Mr Finn said the occasion was a "unique" event to mark the retirement of the Iroquois fleet, honour those killed in the 2010 crash, and raise funds for the Trust.
Mr Finn said Sergeant Stefan Sloan of the Air Force approached the New Zealand Whisky Company with the idea.
The Iroquois entered service nearly half a century ago and were used in tactical air transport, counter-terrorism, humanitarian aid and disaster relief, and search and rescue operations.
A Defence Force spokeswoman said people who had worked with the Iroquois or had a special connection to the choppers would be present at Ohakea tonight.
An Iroquois crashed at Pukerua Bay north of Wellington on Anzac Day 2010. Another crashed in the Kaipara area in 1972.
