The Serious Fraud Office failed to consider key evidence in the $1.7 billion South Canterbury Finance investigation which has led to charges against two senior executives being dropped.
Adam Feeley, the head of the SFO when charges were laid two years ago, described the 14-month inquiry as the "most resource-intensive and time-consuming in recent history". He said the "value of the fraud alleged to have been committed exceeds anything in the history of white-collar crime in New Zealand".
The agency laid 21 charges against five SCF executives for fraudulent transactions alleged to total $1.7 billion - including $1.58 billion from the government bailout after the finance company collapsed.
But charges against two of the accused have been withdrawn before the case reached trial, most recently accountant Terry Hutton who faced two charges alleging false accounting in relation to the recording of a $25 million loan advance and a $10 million loan advance.
