A woman who stole more than $20,000 from a rental car firm was allowed to keep her job so she could repay the money, only to be caught in further alleged fraud.
But the Employment Relations Authority (ERA) has found the company did not follow proper procedures in sacking Michal Tiller.
Co-director Edwin Chan said that the fraud almost destroyed his business and the ruling was very disappointing.
Ms Tiller was hired for the Auckland branch of New Zealand Rental Car Services by her partner Daniel Alexander, who owned and ran the business with Mr Chan.
As the branch's finances struggled, Christchurch-based Mr Chan became concerned about its accounts.
