The family requested privacy as they support his rehabilitation.
The New Zealand Rugby Foundation, established in 1986, provides life-long support for players who suffer serious injuries due to rugby. This includes funding and emotional support for the players and their families.
West Coast Rugby Union chief executive Mike Connors visited the family on Friday and said there were signs that Watt was improving when he was there.
"Not long after I left the hospital I received reports that there had been more improvement, which is very good news," Connors said.
"Every day, from what I am hearing, Brogan is improving and that is what we want to be hearing."
Watt was initially treated at Grey Base Hospital before being flown to Christchurch Hospital and has since remained in the intensive care unit. He underwent surgery to remove a blood clot to relieve pressure on the brain. Surgeons removed a piece of his skull during the operation.
The 23-year-old made his West Coast rugby debut last year and was one of the star players in the West Coast pack this season.
The Suburbs Rugby League Club, for which Watt also played senior football, has set up a Givealittle page to help with his general living costs, loss of income, and expenses for his family, who now need to be in Christchurch.
