Another one alleged he drank bourbon and smoked cannabis with Opetaia before being sexually abused.
On Tuesday, Opetaia told the jury he ran a boxing gym and a home for boys in Kelston, West Auckland, and managed Waitakere Boxing Association from the same address.
The defendant told the jury he became an approved carer for boys aged between 13 and 16 and would care for about eight at a time.
"The way I structured the place it would be the last boys home they would be in," Opetaia said.
