Palmerston North Coroner Tim Scott said the group was playing drinking games, which Mr Taunoa lost many times.
They later went out to a garage where they started playing pool. Mr Taunoa wanted to buy the table but one of the family members would not sell it.
"Josh picked up a bottle of vodka that was mostly full and stated that if he drank the whole bottle he could have the table," Mr Scott said.
The person who owned the table and the rest of the group "approved" the suggestion, he said.
But after Mr Taunoa had consumed about half the bottle, his cousins realised it was not sensible and made up a bed for him on the pool table, turned him on his side and left him asleep.
About 6am the following morning, a family member saw him obviously asleep because he was snoring.
Two hours later, another family member discovered him dead.
Mr Scott said at the time of his death, Mr Taunoa was "grossly intoxicated".
"In simple and real terms, Josh drank himself to death in an attempt - while probably already intoxicated - to drink a large quantity of spirits in the belief that by doing so he could acquire a pool table which he desired."
A close family member, who did not want to be named, said Mr Taunoa was not a drinker and he was drinking on that July night only because he was celebrating with close cousins.
"Had he known that it would have caused his death he would never [have drunk so much] - he's got three little boys that he loved very much."
