Alan Bruce Nichol (62) died on Abbotsford Station in the Lee Stream area after being run over by his truck, which he had parked on a slight incline while attending to livestock, on December 8.
He was found by his son who immediately set off an emergency locator beacon, triggering a rescue helicopter crew call-out.
"They were first on the spot," Mr Nichol said.
To pay back the gesture, and recognise the relationship the Nichol family has with helicopter staff, and Helicopters Otago, he decided "we had to do something".
Five lambs were sold to PGG Wrightson Otago for $900, which was given to the Otago Rescue Helicopter Trust this week.
Rabobank, Peter Lyon Shearing and Desborough Pasture Consulting boosted the donation to about $1500.
Paramedic Doug Flett said the gesture had "sad circumstances behind it", but the money would go towards an iPad for the helicopter, which would be used as an easier and more efficient way to access topographical maps and charts while flying.
Receiving money from the sale of lambs was "a little bit different", but the offer was "very generous", as the trust relied on donations from the community to help continue its work.
PGG Wrightson Otago regional manager Grant Edwards said his company bought the lambs in part because it was a great cause, but also out of respect for the Nichol family, long and established clients of the stock and station firm.
