He has eight grandchildren and 15 great-grandchildren - the most recent a great-granddaughter born in Yea, near Melbourne, yesterday morning.
Mr Hogg was equally delighted Isobelle Lucy Webb was named after his late wife, Lucy.
The centenarian has lived all his life in Dunedin, even during World War 2 where he manned the searchlights at Taiaroa Head.
And even though much of his family now lives in Australia, most of them returned to Dunedin to celebrate his birthday milestone with a lunch and then an afternoon tea with his fellow residents at Oxford Court Rest Home.
Mr Hogg said he had never smoked and he seldom drank alcohol, but when asked what the secret to his longevity was, he genuinely did not know.
His son, Russell Hogg, believed it was because he had an active career as a tinsmith and upholsterer, and had remained active in his retirement.
He was an enthusiastic rower and life member in the North End Rowing Club, and played both indoor and outdoor bowls at the Opoho Bowling Club, where he is a past president.
In a celebratory song to his father, Mr Hogg quipped, "It's not often that a Kiwi makes a 100 - not even playing cricket ..."
Despite his age, Mr Hogg said he was still healthy, independent and mobile, thanks to a hip and knee operation seven years ago.
"That's kept me going a bit longer. My knees used to creak badly. Visitors used to say it was my floor boards - it was that loud."
Mr Hogg still rides his mobility scooter to the supermarket to go grocery shopping, and frequently heads off to his local pub for Sunday lunches.
The excitement of his birthday, and being surrounded by so many young family and friends, made him feel like he could live to 110, he said.
