Their son kept on the family tradition and in 2009 re-opened the brewery, which makes the Stoke brand of beer.
People have paid tribute to McCashin on social media this afternoon.
Wakachangi Lager - a beer brand created by Hauraki host Leigh Hart - posted on Facebook that McCashin was a "true New Zealand legend".
"It's with a heavy heart that we say goodbye to a true New Zealand legend, Terry McCashin. Terry is credited with starting the "craft beer revolution" in New Zealand, and changing the course of the beer industry in this country, but he was so much more than that, farmer, family man, All Black but most importantly all round good bloke," the post said.
"Without going into too much detail, it would be fair to say 'we as a brand' simply wouldn't exist today if it wasn't for the belief, experience and 'can do' attitude of Terry and the McCashin family. Our thoughts are with his friends and family at this very sad time. Godspeed Terry," Wakachangi said.
