"We've probably stood the test of time, but a lot of others have come and gone," said Mr Spiers, who has been farming deer in Hawke's Bay since 1978 and who has been a president of the New Zealand Deer Farmers Association and a director Deer Industry NZ.
Maranoa Deer, developing its herd from eastern European lines, and which has twice won the Velexco premier award for commercial velvet production, is offering about 30 stags, focusing on breeding for the venison market.
The foothills of Hawke's Bay, Taihape and Manawatu are regarded as good breeding areas, and the sale attracts 30-40 registered buyers each year looking for venison genetics to get early growth rate into their stags, Mr Spiers said.
Deer were introduced to New Zealand 152 years ago, mainly in the Southern Alps and foothills. Dreams of establishing a recreational hunting mecca were offset by damage to fragile flora and fauna as numbers increased, and by the mid-1900s they were officially regarded as a pest.
The first farming licence was issued in 1970 to farmer Rex Giles, of Rahana Station, near Taupo, a decade later there were 1540 deer farms with about 120,000 head, about 85 per cent red deer, and a decade later the population was well over 1 million.
