The Central Bank launched a probe into OneCoin in April after New Zealand police warned Samoan businesses and churches had invested.
OneCoin is banned in Samoa and has been labelled by authorities as a fradulent pyramid scheme, which the company denies.
Assistant Attorney General Sefo Junior Ainuu said his office is continuing to review an intelligence report from New Zealand police.
The Samoa Observer reports it was referred to Mr Ainuu after the Attorney General, Lemalu Hermann Retzlaff, declared a conflict of interest.
