"We had beautiful wetlands and we were lucky enough to fill it with all that good stuff like native and exotic birds my wife and I bred," said Mr Pirani.
He is also a strong supporter of the harvest of goats from native forests.
"I'm happy with what I've done but I've got one major goal, and that's goat farming in New Zealand. It's something I really think we're being stupid about."
Mr Pirani has served on a number of environmental and farming boards, including the Meat and Wool Board as a member of the Goat Advisory Group, the Eastern Fish and Game Board, Bay of Plenty Goat Farmers Association, the Department of Conservation East Coast Board, and the National Trust of Balance Farm Environment Board.
Mr Parani suffered from a stroke in 2008. He now has prostate cancer. After three years of being clear of it since his first diagnosis, it's "come back with a vengeance".
"I've had a bloody exciting life I tell you."
Mr Pirani's biggest highlight now is watching his mokopunas grow and be educated in the changes he's made.
