Buchanan bought the Lodge Hotel in 1952 and managed it for 35 years. He then sold it and then bought the T & G building in 1986, redeveloping the upper floors.
"We developed that into offices as well as the restaurant and the conference centre and the dining area.
My wife and I retired after that in the year 2000, so I've had a busy life all together and I enjoyed every waking moment."
Despite retirement, Buchanan is known as one of the most active members of the Napier Lions, with plenty of experience under his belt.
"I have loved every minute of being a Lion. I started off in Hastings in 1961, and then they asked me to become president of the Taradale Club, that was two years later. Then I moved over to the Napier club and I've been there ever since.
"We just help the public out on a number of occasions and we make a bit of money here and there, then hand it out to various organisations that require our assistance."
Lions member Judie Stones said Byron's loyalty to the club was a call for celebration.
"He still goes to all the barbecues and most of the events and just loves to help out.
"He's just so much fun and he's always got something to say, always contributes and he's very active. We have trouble keeping up with him to be honest."
Buchanan is celebrating his 96th birthday at home, surrounded by friends and family and said he had no plans to retire from the Lions.
"I'm not going anywhere, I'm having far too much fun. We've got 35 members in the club at the moment and it's just great being part of such a good group of people," he said.
