Bryers pleaded guilty in Auckland District Court today to charges of failing to keep adequate records and failure to attend a watershed meeting for the Swordfish Lodge resort on the Whangaparaoa Peninsula, north of Auckland.
He also pleaded guilty to a charge failing to attend a meeting for creditors for the Bribanc property group.
Possible sentences for the charges include imprisonment.
Four other related charges were withdrawn by the Ministry of Economic Development following the guilty pleas.
Bryers still faces 69 criminal charges on other matters, to which he pleaded not guilty today.
Sixty of the charges were laid under the Companies Act, mostly alleging failure to keep adequate records and making false statements.
The other nine were laid under the Financial Reporting Act, four relating to Northern Crest Investments and five relating to Bryers' Marinc company.
Bryers was remanded on bail to reappear in court on October 23.
