Hackshaw did make interest payments to the beneficiary for six years, but then took the $10,000 through a series of withdrawals before closing the trust account when she sold her practice.
The New Zealand Lawyers and Conveyancers Disciplinary Tribunal found that she misappropriated approximately $10,000, and this amounted to misconduct.
She was struck off the roll, ordered to pay compensation of $10,000 to the estate and to pay the New Zealand Law Society costs of $10,518 and also to reimburse the costs of the hearing.
Law Society President Kathryn Beck said Hackshaw was in a position of both privilege and, trust and she abused it.
"To deprive the beneficiaries of this estate when she was entrusted to look after this sum of money is appalling behavior that won't be tolerated," she said.
