Fendall repaid $450,016 to the insurer and was complained about to the New Zealand Law Society.
From 2004 to 2009 Fendall was paid more than $2.5 million from the public purse.
In October 2009 Fendall was suspended by the Legal Services Agency for allegedly overbilling as a supervising duty lawyer at the Waitakere District Court in West Auckland.
In 2011 Fendall pleaded guilty in the Tribunal to a charge of misconduct in her professional capacity relating to making excessive claims for legal aid payments to which she was not entitled. She was censured and ordered to pay costs.
The Tribunal said Fendall's conduct was at the serious end of the spectrum. It ordered that she be struck off with effect from August 24.
"It is essential that members of the New Zealand legal profession must be totally honest in everything they do. Anyone who engages a lawyer must be able to expect that they will be obtaining advice and services from a totally trustworthy individual," Kathryn Beck, president of the New Zealand Law Society said.
"When a lawyer is found to have made false statements or declarations for any reason, the integrity and reputation of the whole profession is threatened."
Fendall said had nothing to say when approached by the Herald.
