She made a further application to Immigration for another permit without instructions and made false representations in support of that application.
She was found guilty of eight charges, including two of misconduct.
New Zealand Law Society president Chris Moore said it was unacceptable for lawyers to mislead clients and third parties.
"The overriding duty of a lawyer acting in litigation is to the court concerned. A lawyer must not act in a way that undermines the processes of a court."
Meanwhile, Mr Skagen faced 12 charges of misconduct relating to three separate matters.
While acting for two separate clients, Mr Skagen breached the intervention rule by not having a solicitor accept fees, and taking them in advance without having them deposited in a solicitors trust account, as well as failing to act in a timely and competent manner, the tribunal ruled.
Mr Moore said the law "clearly states the accepted practice", which Mr Skagen did not follow.
"A barrister sole cannot accept instructions to act for another person other than from an instructing lawyer who holds a practising certificate as a barrister and solicitor," he said.
"A barrister sole is not a solicitor and cannot receive or hold money or other valuable property for or on behalf of another person."
