In a statement provided to the Herald, Green's family said he was "an awesome dad and was the absolute heart of his entire family".
"Roy was a ray of sunshine for us all. He is loved very deeply by his wife and kids, his mother and siblings, and was extremely close with his extended family and the wider Pukekohe community.
"Roy was so proud of all that he had achieved - he owned his own business and had a beautiful family.
Green was interviewed by TVNZ during the level 4 lockdown, saying it was a struggle to pay the bills and his employees with no money coming in.
Butchers were controversially not allowed to open during the lockdown, despite supermarkets being allowed to sell meat.
At the start of the lockdown Green posted to Facebook saying he was enjoying the four-week "holiday" with his young family and telling Franklin locals to stay home and stay safe.
"I spend nights awake in bed, some nights I've sat there crying, wondering what I'm gonna do next."
The neighbouring fruit shop was open for business, which Green said was "just not fair".
He was taking orders over Facebook trying to bring in some money.
Green Family Butchers paid 16 employees $95,000 from the Government's wage subsidy scheme, according to the wage subsidy search.
Police confirmed they were called to a Tuakau property after 10pm on Sunday.
"A 38-year-old man was located deceased at the address. Police are not treating the death as suspicious and it will be referred to the Coroner."
Under the current level 3 rules butchers are allowed to operate, if they can deliver or run a click-and-collect or phone order service. Customers are not allowed to come in store.
On April 25 a post to the Mad Butcher Pukekohe Facebook page said the shop would not be opening in level 3.
Flowers have been left outside the shop since Green's death, and there are hundreds of tributes to him online, calling him "one of life's great characters", "generous", "beautiful", "cheeky" and a man with the "biggest heart and always put smiles on peoples faces". His death was a "huge loss" to the community, one poster said.

A post by Tuakau Rugby League Club said although Green did not play, he had supported the club on many occasions.
