"He was very supportive of all his children, grandchildren and great-grandchildren."
Ms Henwood said he passed away peacefully at Whangarei Hospital on Thursday after his health took a turn for the worse.
Mr Morgan's sixth great-grandchildren was born on his birthday, a month ago. "It was very special," Ms Henwood said.
Mr Morgan spent his life farming. He was appointed to stay in Northland during World War II to help the women work the farms. He contracted to farms from Ohaewai to Motatau.
"He worked for everyone in the community," Ms Henwood said.
He spent time working for the A&P; Society, the local golf club, he was a welder, and was a life member of the Hukerenui rugby club.
Ms Henwood described the Jack Morgan Museum as a community tribute to her grandfather.
The museum opened in 2010 next to his local watering hole, the Hukerenui Hotel, and features a wide array of items he collected in his lifetime. Mr Morgan would visit the museum on his modified ride-on mower.
In April Mr Morgan received the Paul Harris Fellowship, Rotary's highest honour.
