The young Invercargill man shot dead on Stewart Island had helped build a hunters' hut on the island with his father and been on the local deerstalkers association's executive.
Samuel Phillip Long, 24, died at the scene after he was shot by another member of his five-person hunting party, police said.
He was alone when he was shot on Monday.
A New Zealand Deerstalkers Association Southland branch member, Douglas Gordon, said Mr Long and his father, Steven, had a very close association with the hunting club.
"They are both good members of the club and good members of the executive. It will be a sad loss."
