Lawyer Quentin Duff - son of Once Were Warriors author Alan Duff - has been censured by the profession's disciplinary tribunal and called reckless for not disclosing he directed companies which had gone into liquidation.
Duff admitted a charge of unsatisfactory conduct before the tribunal, which accepted he had not acted dishonestly.
The issue arose after he completed an application to renew his lawyers' practising certificate in 2014 and declared he had not been a director of company put into liquidation.
That declaration, according to the tribunal, was incorrect because Duff had been the director of three wound-up companies.
One of these was Duff Legal, which was put into liquidation following an application by Inland Revenue, Companies Office records show.
