Malele Paulo, also known as King Faipopo, has been jailed for four years, and co-defendant Lemai Faioso Sione will spend four-and-a-half years behind bars.
Both men were found guilty by a panel of assessors in March this year.
Supreme Court Justice Vui Clarence Nelson ordered media not to publish evidence of the case as another co-defendant Talalelei Pauga is yet to be extradited to Samoa from Australia to stand trial.
