Wellington club player Daniel Baldwin, 19, died last Wednesday after suffering an injury in a game the previous weekend. His funeral was on Tuesday.
Moody played for the New Zealand Barbarians in 2013 and was a trialist for the New Zealand under-20s side the following season.
Moody's club coach and mentor, Tonga Taumoefolau, who has been at his side since he became ill, says Moody will be remembered as a family man who embraced being the best father, brother and son.
"Bevan was an active rugby player with Marlborough Boys' College First XV, Waitohi and various representative teams. He had unique abilities as a scrummager and had the physique to be a star on the rugby field.
"His team embraced him as a teammate who was hard-working on the playing field; a committed and loyal team player. He just loved playing rugby. Bevan was called "Bear" for his imposing physique, and was a much-loved team mate at every level he played."
Tasman Rugby CEO Tony Lewis said Moody's death was a shock for eveyone.
"The thoughts of everyone in the Tasman rugby community are with Bevan's partner and family. This is a devastating time and our support and prayers are with them," said Lewis.
"This is a massive shock to all of us. We are a tight-knit community and the death of someone so young has hit hard in his club and across Tasman rugby.
"Bevan had a solid rugby future ahead of him. He's been a New Zealand Under 20 trialist and was on the fringes of the Tasman Makos. He was well known and liked, and is a huge loss."
