The Serious Fraud Office has thrown out a complaint from Affco against the union representing its locked-out workers.
Meat processing company Affco lodged an SFO complaint on April 5 after alleging there were irregularities in the accounts of the New Zealand Meat Workers Union.
Its chief executive Hamish Simson said the union, which is representing about 1400 workers locked out by Affco, had not declared all the income gained from fees paid by its 23,000 members.
SFO chief executive, Adam Feeley this afternoon said an immediate evaluation of the information provided to investigators failed to find any evidence of fraud.
"We encourage any member of the public to contact us where they have any reasonable grounds to believe that a serious financial crime may be taking place. However, it is equally important that the resources of law enforcement agencies are not unnecessarily drawn into matters where other, more appropriate, courses of action are available."
