Khan was at the casino in Christchurch for dinner with friends and family a day before the game against the West Indies, which they went on to lose by 150 runs.
He apologised for his actions which offended the public and cricket fans in Pakistan, where gambling is viewed as taboo.
But Pakistan Cricket Board chairman??Shaharyar Khan said the matter had been investigated and no further action would be taken against the former national team coach.
“Moin clarified in a statement issued earlier he only went to the casino for dinner with his wife and a friend and his wife,” Shaharyar Khan said.
“He has admitted his fault. It was inappropriate for him to have dinner at the casino. The matter is now closed.”
